Title: Shinko 230 Tourmaster Tires...Thoughts? Post by chzeckmate on 11/09/15 at 02:07:41 I need a new set of tires and my situation demands something budget friendly. I'm looking at the Shinko 230 Tour Maaster set seen here http://www.bikebandit.com/tires-tubes/motorcycle-tires/shinko-230-tour-master-motorcycle-tire Thoughts? |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by Dave on 11/09/15 at 03:42:29 If you are going with the 100/90-19 front and 130/90-15 rear option, the Shinko 230 is a good choice for an affordable set of tires.......and you can also go to the 140/90-15 rear as well. The reviews on Bike Bandit seem to be really good for this tire (It is a shame however that the reviews are always made when the tire is new and folks don't have much experience with the durability of the tire). The tread pattern is a bit unconventional when compared to other modern tires. If you go to the 100/90-19 front and 140/90-15 rear, you might also consider the Shinko 712. It has a more conventional tread pattern - not sure if the center groove on the front tire would cause it to want to follow grooves in the pavement.....a lot of tire companies have a zig/zag pattern in the center groove to help stop the tire from following rain grooves (in the review for the 712's no one mentioned this as being a problem). All of my bikes sometimes try to follow the pavement grooves a tiny bit....regardless of the tire I have on the bike. For the price of these tires, and with free shipping, if you are mounting the tires yourself....they will get you a new set of tires at a really good price. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by WD on 11/09/15 at 09:24:17 Have the 230 on the back of the 1500 Drifter. Wears the same as the last Michelin Commander 2 we had on it. Drifter is 77hp and over 800 pounds. Have the 712 on the front of my 03 Savage. Has gone 2 summers and change while I've owned the bike. Pine (FSO) had it put on the bike in 2013 when he owned it. It does like to rut track, but with the good wear characteristics, fair trade off. I need to do my rear tire, today. Swapping the complete assembly off the 2003 for the complete assembly off the 1998. Going from a completely worn smooth and square Dunlop Qualifier (1994 or 2004 coded, Intruder 800 oem tire) to a Cheng Shin that was installed in 2000 and still has about 4 months worth of tread on it... After that, I'll swap on the tire (almost no miles Kenda 130/90-15) installed on Lisa's deceased 800 Intruder. I run them until they are slicks or the sidewall lets go. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by chzeckmate on 11/09/15 at 12:10:08 Dave, I'm definitely going to go with a 140/90. I do believe the zig zag pattern does help with tracking. The price is certainly a factor. I'm currently in need of a value option and the 230's price tag is about as high as I can go right now. There are other tires that are cheaper but, as you mentioned the reviews play a role in the choice. I too wish there were more reviews after some mileage and experience. WD, It's good to hear that the wear for the 230 is comparable to the commander. I'm really interested in how it does in the wet. The reason I'm not going with the 712 is I have a little experience with that tire. The wet performance of the 712 is lacking, IMO. I'm willing to spend a little more for the 230 for better wet performance, but I'm only going off of reviews and second hand information. I really worry about wet performance on the Savage. Once in a slide, the Savage is unforgiving. It's not like my Aprilia, where I can be in a full slide and the Battlax tires will grip at the last millisecond and the bike will right itself. I'm not expecting the 230 to make the Savage do that, but If I can avoid the slip to begin with, that would be ideal. The stock IRC tires wet performance is not good either. That's why I didn't go with that value option. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by Dave on 11/09/15 at 12:46:04 The tire manufacturers that make really good "wet weather" tires like to talk about their "silica tread compound" that makes the wet weather performance so good. The Shinko website doesn't mention Silica....but claims they are good in the wet or dry. http://www.shinkotireusa.com/tire/230-tour-master My only current experience with riding in heavy rain is on Sport Touring tires...Pirelli Sport Demons and Bridgestone Battlax BT45. I have on occasion ridden pretty aggressively through the rain to get somewhere warm and dry......and I am amazed how much traction they provide in the wet. However- I always slow down for wet leaves, manhole covers, railroad tracks....and especially wet crosswalk and turn arrow striping.....those painted surfaces are really slick when wet. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by xaman on 11/09/15 at 18:36:10 Hey Czech, I put knobbies on mine and have my old tires just sitting around. The front tire is removed, the rear is still mounted to the wheel (not on th bike.) You are welcome to the tires if it would help you. I live in Huntsville, so I'm guessing we could find a way to pass them off. I'm traveling tonight and will be home tomorrow evening. I could take a couple pics then for you to see the tread and such. Dunlops if I recall correctly. I bought the bike used and immediately starting changing things, so I didn't pay a ton of attention to what was on there... Totally understand if you'd rather go new, just thought it might help if the budget is tight. :) |

Wow, that's really generous of you to offer. I can't tell you how much it means to me. I actually went ahead and ordered the Shinko 230 set (100/90, 140/90) a couple of hours before you posted. I'm going to call the customer service tomorrow and ask them if they can cancel the order. If they will do that then I would love to take you up on your offer. That would give me the time I need to put more money together and buy a good quality set later when it's not such a hardship for me. One way or another we should definitely get together since we're in the same neck of the woods. Cheers! I really appreciate it! |

I tried to call customer service yesterday but was on hold for too long and had to get back to work. Was going to call today, but before I got a chance they had already arrived. I'm going to go ahead and mount them. The rear is definitely wider than the stock IRC 140/80, but I know others have mounted it without issue so I don't anticipate any problem. I'll post pics when it's done. http://i1297.photobucket.com/albums/ag28/justin_fisher2/tires.230.shinko_zpsohis0tiw.png (http://s1297.photobucket.com/user/justin_fisher2/media/tires.230.shinko_zpsohis0tiw.png.html) @xaman, I really appreciate you buddy. We definitely need to get together sometime since we're so close. I'm working every day now from early morning to late at night, but I expect that to change soon. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by xaman on 11/11/15 at 18:37:37 Those look great to me. I've had good luck with Shinkos, in fact that's what I'm running on my savage now (804/805) series. Hopefully we can connect for a ride before it gets too cold to be enjoyable. But I just took my savage to the doctor in OK for a few weeks visit. I'll have to ride my DR650 until the savage comes back. Good luck mounting those tires. Do you have a machine, or are you doing it the old fashioned way??? |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by Dave on 11/12/15 at 04:43:23 I am looking forward to your ride report and long term testing of these tires - so you can give us a report on the Shinko 712 vs. 230 performance. I am always a bit reluctant to order tires in the fall, as we get winter up in this area and it will be 5 months before I can use them again. Most likely the tires were made a few months ago....so the tires are a year old before I ever get to use them. What are the date codes on the sidewall? There will be a 4 digit code that is melted into the tire when it is made that shows the week and date the tire was made. Most likely the code on your tires will look something like "1315" - which would be the 13th week of 2015. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by Serowbot on 11/12/15 at 08:31:17 I'm just about ready to get new tires also... I'm a Shinko fan... and will have to choose between the 712's and the 230's... The 230's cost just a bit more, but are supposed to wear longer... Having 2 bikes has cut my yearly mileage down to 3 or 4 k on the Savage... ...with most trips over 100 miles round trip, being relegated to the Sportster... I will likely stick with the 712's... (unless the dealer gives me a sweet deal)... The 712's prettier... ;D ;D ;D... Pretty, pretty, pretty... that's what counts in a tire... ::)... No offense... those 230's are pretty too... 8-)... |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by chzeckmate on 11/12/15 at 16:46:10 Okay so, I got the Shinko 230 Tour Master tires mounted today. The date on them is 3615. I will give you my first impressions in two parts because I want to give my evaluation of the tires performance and I also want to give my impressions of going from a 140/80 rear to a 140/90. So, performance is very impressive for the price. Handling reminds me of the Pirelli MT75. I purposely took the bike to a number of different road substrates and textures. I immediately noticed that the tracking is true no matter how deep the rain grooves and tar snakes seem nonexistent. imperfections in the road can be felt but are muted. Stability is instantly noticeable at high speed. The flatter and wider contact patch delivers comfort and inspires confidence. In this sense, the 230 reminds me of the Metzeler Marathon ME880. Diving into a tight curve feels unusually comfortable for a cruiser on these tires. I found myself leaning over considerably further than I would have ever recommended to anyone else. I did in fact notice that in the twisties I was riding a lot more aggressively than I should have been on new tires. Overall, for performance/value, I can easily say that this set of tires is a win. I will of course reserve final judgement once these have some wear and I will revisit this to add more thoughts incrementally as mileage accumulates. At the moment I will say that I was literally stunned by the performance of these tires for the money. I would expect to pay more and would have without complaint. Now I want to touch on the change to the 140/90. With this new rear tire everything changes. Riding posture, final gearing, acceleration, top speed, lean angles, responsiveness, everything. I immediately felt like I was riding a different bike. Muscle memory developed on the previous 140/80 failed in every way and I instantly understood that I needed to treat the experience as if I were riding a different bike. I was at once confronted with a sense of apprehension. That said, this bike was meant to have a 140/90. It changes the final gearing just enough that I can run around town in second gear most of the time. The top of second is right around 38 MPH. the larger tire changes my riding posture just slightly but it is more natural. Acceleration feels more natural too. Traversing uneven roads easier. Course corrections make it feel like a larger bike. Cruising in fourth no longer sounds labored. The motor hums at my typical cruising speeds over 40 and doesn't sound labored until long after I'm already breaking the law...which I never do ::) Don't get me wrong, if you couldn't break the ton before you're probably not going to after the change, but you will absolutely notice the difference during normal operation and it is so worth it. If you've been on the fence about going to a 140/90 then let me help give you the nudge you need to do it. You will not regret it. So that's it for now. If you have questions about the Shinko 230 let me know. I'm happy to help. Cheers! http://i1297.photobucket.com/albums/ag28/justin_fisher2/rear_zpsagvahz45.jpg (http://s1297.photobucket.com/user/justin_fisher2/media/rear_zpsagvahz45.jpg.html) http://i1297.photobucket.com/albums/ag28/justin_fisher2/front_zpshjdf0s7z.jpg (http://s1297.photobucket.com/user/justin_fisher2/media/front_zpshjdf0s7z.jpg.html) |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by dustystranger on 11/12/15 at 19:43:49 Yeah the tourmaster is one of the best, long lasting tires I have ever used. The712 is also very good. I prefer a 130 on the rear. Of course I spend most of my time in the twistys. My s40 has never seen an interstate. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by Dave on 11/13/15 at 07:57:56 chzeckmate: Now you have me curious. I bought a theft recovery bike a while back, and it has a Dunlop D404 on the back that is a 140/90-15. I might have to throw that tire on the bike I have with the stock IRC tires and see how the ride changes. I also have a 110/80-18 that I could put on the back if I really wanted to do a comparison! dustystranger: You prefer the 130/90 over the stock 140/80 for what reason? Nimbleness, ride quality, gearing, acceleration? |

I think you'll be surprised. The 140/90 makes a lot of changes to the dynamics of this bike. All of the changes individually are small but together the changes create a whole new experience. I don't know how the D404 will compare to the stock IRC as far as grip, comfort, and handling, but I would expect it to be better. The thing about the 230 that I just can't get over is how it has almost eliminated groove wander and tramlining. This morning around 2am I took the bike to a place that I usually hate to go because of how the horrendous grooves and cracks in the road would send me back and forth across the lane on the IRC. I have to go there every so often because it's the only way to get to that particular destination. I have always dreaded it on this bike. I wanted to see how the 230 would handle there and I was delighted to find that the 230 treated this stretch of road almost like fresh blacktop. If the performance of this tire holds up, it will be my permanent choice. It's very clear to me now why the 230 is the most popular Shinko. |

[/quote] I'm not sure how those time frames translate into mileage. I'd like to get more than 16 months out of my tires. I'm putting about 150 miles a week on the S40 right now. I'm buying a 2013 CBR500R in January and I expect that to change. I'll probably put maybe 100 miles a week on the S40 then. I'll be reporting on the wear of my tires as it accumulates. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by Dave on 11/15/15 at 17:20:34 Well I wasn't/didn't move the Dunlop D404 over to the stock Savage to try. I measured the width and looked at the fender clearance on the bike it is mounted on, and it won't clear the saddlebag brackets even with the low profile bolts I used to mount them. The stock IRC 140/80-15 measures 132mm wide - the Dunlop D404 in the 140/90-15 size measured 142mm.....it is 10 mm wider. Perhaps the Shinko isn't that wide - the Dunlop has a big chunk of rubber molded onto each side of the tire where the tread meets the sidewall, and this sticks out pretty far and would hit the saddlebag support bolts. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by chzeckmate on 11/17/15 at 06:21:57 Update: It rained here in Houston through the night and I took the opportunity to test the wet performance of the 230. I'm absolutely thrilled with the results. The wet performance would hold up against any major brand tire and outperform most. I took the bike out to several places where I routinely have trouble with traction. A manhole cover, some painted road markings, and a gravelly patch specifically. I took on these hazards at my usual pace and they felt as good as dry road. I went back over them several times increasing speed each time to the point of maybe being a little reckless and came away with a wider smile each time. I really like these tires in the wet. I'll be able to ride with confidence in any weather condition now and that's what I was really looking for. These tires get my stamp of approval as a great all weather and all road surface tire. I do hope the performance holds up over time. I'll report on that as I accumulate more mileage. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by Dave on 11/17/15 at 09:58:39 Glad the tire is proving to be a good fit to your riding style and needs. I did some math: The stock 140/80-15 IRC tire is supposed to be 128mm wide on their chart (I measured 132mm wide), it has a rolling distance of 75.681". The Shinko 130/90-15 is supposed to be 129mm wide according to their chart, and it has a rolling distance of 76.058" - which is an increase of 1.005% in gearing. With the stock IRC tire at 4,000 rpm you would be going 3,980 rpm to keep the same speed with the 130/90 Shinko (dropped 20 rpm). The Shinko 140/90-15 is supposed to be 142 wide (close to your 144 measurement), and it is supposed to have a rolling distance of 78.28" - which is an increase of 1.0343% in gearing. At 4,000 rpm with the stock IRC you would be going 3,866 rpm at the same speed with the larger 140/90 (dropped 133 rpm). I will try and fit the Dunlop on with the saddlebag brackets.....just to see if it can work. I really would like to see how it rides/handles....then throw on the 110/80-18 and see if I can feel any big change in handling. (I would hope I can notice a change!) |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by Serowbot on 11/17/15 at 10:26:09 I'm confused... Shouldn't a 3 inch difference on a length of less than 100 inches, be over 3%?...

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by jcstokes on 11/17/15 at 10:36:05 I've been running 140/90 15 since the stock IRC wore out. I've had no complaints. There was a post here about the 140/90 having more unsprung weight, which supposedly conspires against handling. I've had no issues with this and lets face it, our bikes aren't really sport machines or super bikes. |

I think the rpm difference is a little more than that. Of course, I'm going by speed/rpm on the Shinko. The same speed I would have achieved at 4,000rpm on the IRC is achieved on the Shinko with a difference in rpm of about 200 rpm, but it's important to remember that your numbers are comparing a new stock IRC 140/80 to a new Shinko 230 140/90. My IRC was almost treadless so the diameter of my used tire is what I'm comparing. That would explain the difference, I'd think. The 200rpm difference feels (and sounds) really good. 6B787E7D6F68680A0 wrote:

This is exactly my experience with the handling of the Shinko 230 140/90. It does require a heavier hand to drop into a tight turn and I like that a lot. I'm heavy handed by nature, and it feels much more natural to me to have to take more command of the line. The loss of acceleration is almost imperceptible and easily overcome by a slight change in riding style. You mentioned you thought you'd lost some top end, but I have gained on the top end and I would think the math would support that as well, but even if you did lose some top end I'd think it's well worth it for the gains in overall performance, fuel economy, and the other items on my previous list of improvements the Shinko 230 140/90 provides. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by Serowbot on 11/17/15 at 23:07:01 The more unsprung weight,.. the more inertia to fight with the suspension... This means more time with less tire contact,... also, more weight for the engine to overcome in getting the bike moving... ...but,... more tire also creates more centrifugal force, giving more stability on the highway...

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by chzeckmate on 11/18/15 at 01:44:44 I appreciate the points made about unsprung weight. It makes me wonder what the weight difference between the stock IRC 140/80 and the Shinko 230 140/90 (and other brands/sizes) actually is. Are the 140/90 tires actually heavier and if so, by how much? It would take a lot to convince me that unsprung weight actually becomes a real issue changing from the stock tire to a 140/90. I mean, I know the argument but I believe this is negligible on this bike. I'd think that most of us here have done enough weight reduction to offset this anyway. My experience is that both the handling and the stability is greatly improved and I understand that I'm not alone in this experience. That's definitely real. It's my belief that the stock tires cause the steering on this bike to be too sharp, which as we all know leads to instability over rough surfaces. I had considered getting a fork brace at one time but now I don't want it, don't need it. This tire change has eliminated that thought completely. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by Dave on 11/18/15 at 04:05:15 The acceleration is affected both by the mass of the tire and the radius of the tire. The formula for inertia of a cylinder is: I =1/2 mass x Radius squared. So a heavier tire slows down the acceleration a bit by the extra weight, and also by the larger diameter. The radius used is not the outside diameter of the tire - but the radius of the mass center of the tire profile. For the larger/wider/heavier tire the radius is increased over the stock tire. If you are not drag racing your Savage.....the reduced acceleration is most likely not an issue as you will still be able to accelerate with normal traffic you encounter on public roads. The extra inertia of the larger tire that makes it accelerate a bit slower also makes it resistant to a change in speed and direction. Braking will be just a bit slower.....mostly from the additional rotational inertia and a tiny bit from the extra weight moving forward. The additional rotational mass will also make the bike a bit more resistant to directional change when initiating a turn or coming out of the turn. Again.....this is not an issue unless you run timed events in the slalom course, or your buddies are leaving behind in the curves and won't wait for you at the next STOP sign. The additional stability might even be a welcome change for some riders. The bottom line is that if you use your bike as a Canyon Carver.....you might want to stay with the smaller tires that are available. If you use your bike as a commuter or touring bike, the larger 140/90-15 might be a better choice. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by chzeckmate on 11/18/15 at 04:28:56 You're right about that. I definitely welcome the additional stability and traction, not to mention the higher top end, fuel economy, and quieter engine at higher speeds. The loss in acceleration is not noticeable unless you're coming hard off the line and even then it's almost imperceptible. What I notice is smoother acceleration in general. As for braking, I upgraded my front brake pads while I had the front wheel off so my braking is better than it's ever been. Now that I've done this I'm even more eager to get the 428 chain conversion done. It will have to wait awhile, but I'm feeling really good about it now. |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by Art Webb on 11/18/15 at 10:57:15 Shinko I'm using is the 712, which may be a bit different than the 230 I could get up to 90-95 mph on the stock IRC, might hit 80-85 on the shinko Of course there's a bit of speedo correction involved, but not, I think, a full 10 mph as far as traction, it's a non issue on a bike as light and low powered as a Savage, the stock 140 / 80 (in a decent tire) has more traction than this bike really needs, and so does a 130 / 90, in a decent tire (no, IRCs are not decent tires ;)) I've gotten used to the bike "humming' along at 70 since I moved out of town, so that's not an issue (I didn't see much of a change anyway) Of course you went from a wore out IRC to the 230, so near anything is an improvement ;D I might try the 230 next time, on your recomendation, if I don't go Pirelli MT66 (also budget priced and highly recommended, but not available in 140/90 I don't think) stability has never been an issue for me on the Savage (except the crappy IRC tracking grooves like a slot car) I came off a Ninja 500, and before that a Rebel, neither as stable as the savage (wish I'd kept the Ninja, I could use it for a commuter and just use the Savage for easy ridin) that bit of extra resistance in the steering puts me off a lot, though, and I'm slow in the tight stuff as it is (Captain Slow I am ;)) |

Title: Re: Shinko 230 Tourmaster Tires...Thoughts? Post by chzeckmate on 11/18/15 at 18:14:28 Important Update: So I inspected the rear tire today just to see how it's wearing and noticed a shiny thin line (looked like a thin line of tire polish) going around the right edge if the tire. I knew immediately that the saddlebag support bolt must be rubbing occasionally as I hit deep depressions, ruts, or potholes to make that line. I went to the hardware store and got some M8 carriage style allen bolts to replace the stock bolts and everything looks just fine now. |
