Title: Rear Wheel Options after chain conversion..
Post by heroicseven on 05/25/13 at 08:58:47

Hello,
I'm considering a chain drive conversion and wonder if the chain drive would allow enough clearance to lace a larger wheel on the back hub without having to modify the swing arm.

Anyone have any thoughts/experiences?
thanks

Well,, Id Guess ther'll be a bit more room there. depending on how far off the case the sprockets hold the chain. Its not as if the chain will be located where the outside of the belt IS & the difference between belt & chain widths is suddenly available for a wheel to run in there. Id suggest you make the swap to chain & see what you have.

Yup,.. not much change... swingarm is the limiting factor...

Yes I have done it. :)
I run a 170 on the rear.  :D

I have a chain drive conversion on my bike and the rear tire (140/90 - 15) sidewall to chain clearance is 1/2". I have a 17 tooth front and 43 tooth rear sprockets. There are some clearance issues....the beltguard mount on the swingarm near the pivot shaft and the beltguard mount in the middle of the swingarm need to be bent out of the way to clear the chain.

One more pic of the chain drive clearance.

If anyone is interested I have two chain drive kits for sale. Sprockets are a 17 front and 43 rear with a Heavy Duty 530 chain (7600 PSI tensile strength) and includes the necessary front sprocket spacer. The chain is cut to the proper length for a stock swingarm. The OEM pulley ratio is 2.96 and the Chain Drive Conversion ratio is 2.53. This lowers your top gear RPM by 580.

Chain drive then you switched it to a 170 hey... sound awsome and looks it to.

It was a costly exercise due to location. But realitively easy to install.
There are a couple of little tricks like off setting rim 4mm and spacing the sprockets out.
I have done nearly 5000km now and its great.
Great to ride. :D

The kits I make don't need a rear sprocket spacer...just one for the front sprocket so the front and rear sprockets align correctly.

You can make the chain conversion kit for roughly $80, you only need a 110 link chain.

Title: Re: Rear Wheel Options after chain conversion..
Post by Super Thumper on 05/28/13 at 09:13:14

I don't known where you are getting the parts for the chain drive conversion or what the quality is but $80.00 is less than my wholesale cost for the parts In use in my kits :o

Title: Re: Rear Wheel Options after chain conversion..
Post by Super Thumper on 05/28/13 at 09:15:30

With the rear sprocket mounted flush to the rear wheel hub the side clearance between the tire sidewall and the 530 chain is 1/2". that could be increased by the use of a spacer.

From amazon.com, 9,000lb tensile strength 530 chain $40, $25 rear sprock, $10 front sprock, $5 for a box of m2 4 flat wwshers...

I'm curious to know how much your selling your chain conversion for? Also does your kit come with the front sprocket spacer? AKA=Complete?

Title: Re: Rear Wheel Options after chain conversion..
Post by Super Thumper on 02/20/14 at 06:14:30

Chain drive kit is complete including the front sprocket spacer.

$129.95 and includes FREE Priority Mail shipping.

Post by Mario Verasso on 02/20/14 at 15:53:39

Does the spacer offset the sprocket? Is that how you can run a 170? Or did you modify you swing arm too? Please more details...

Title: Re: Rear Wheel Options after chain conversion..
Post by Super Thumper on 02/21/14 at 08:57:33

NO modifications are needed to the swing arm except to bend the two belt guard mounting tabs out of the way to clear the chain as depicted in the pics on my web site. The spacers are needed to properly align the front sprocket with the rear one. The 17 tooth front sprocket and the 43 tooth rear yeild a 2,53 to 1 ratio which is 15% taller than stoch, lowers top gear RPM by 580 rpm. Example: RPM at 60 MPH with the stock belt drive (296 to 1 ) gives you 4000 RPM, with my 17/43 chain drive conversion the RPM at 60 MPH is 3420. Other ratios are available as a special order at the same price. 9600 psi O-ring chains are also available as a special order. As always, I ship FREE!

I have included a pic here of the kit installed on a Savage. the sprockets are 17/43. The chain is a non-o-ring 530 chain 7600 psi chain. As you can see there is ample clearance, a possible 18 tooth front sprocket is possible as some other members have indicated. the 17/43 sprocket set is a good compromise between lower top gear RPM economy and lower rider/engine stress. Go any taller with the gearing and a stock engine will require some clutch slipping to get under way from a stop in 1st gear. My engine is a fully built 700cc "Super Tumper" so I can still take off without any clutch slippage even in 2nd gear with my 2.53/1, 17/43 gearing. I would recommend a Barnett heavy Duty Clutch for anyone who needs to replace their clutch....MUCH better than stock!!

FYI...the Suzuki DR650 dirt bike puts out 46 HP and only uses a 525 chain so the 530 I use is enough to handle even a fully built "Suter Thumper" with NO problems....I have over 2000 miles on mine and only had to adjust the chain once!

How much of a spacer is needed behind the front sprocket, please?

Just about to do the conversion myself, and the Winsor cycles website didn't allow an option to ship to the UK

You need to explore the Technical Section, there is a Table of Contents with links, and in that you can scan down to the rear suspension portion.  There you will find a "How To" for the chain conversion.

Or click here since I alread did that for you......

Thanks buddy, I've spent a loooong while going through the tech section, as a brand new savage owner, but must have missed that!! :)
