Title: Rear wheel/brake swap Post by barry68v10 on 04/15/07 at 08:35:54 Does anyone know if you can swap an LS650 rear wheel assembly for something out there with a single disk rear brake? Either 15 or 16" wheel would be fine. Thoughts? |

Title: Re: Rear wheel/brake swap Post by LANCER on 04/15/07 at 11:40:50 I am working on a sporty mag wheel. The axle sizes are different which may require a sporty swing arm or finding a bearing set that will fit the sporty wheel and the Savage axle. I will be visiting the HD house this week to see what is available. |

Title: Re: Rear wheel/brake swap Post by barry68v10 on 04/15/07 at 13:21:47 Is the sporty wheel 16"? I'd be interested! |

Title: Re: Rear wheel/brake swap Post by verslagen1 on 04/15/07 at 16:02:10 The chain mod people used the sproket off of a GS550. I just checked the fiche for a 1980 GS550 with a cast wheel. And it has a disk brake! You might have a donnor if you can stand cast wheels. |

Title: Re: Rear wheel/brake swap Post by Greg_650 on 04/16/07 at 10:47:12 Now ALL you have to figure out is the hydraulics to operate the brake :P |
|
Title: Re: Rear wheel/brake swap Post by verslagen1 on 04/16/07 at 11:34:02 Guess what? the GS550 also has a hydraulic rear brake pedal, not much to figure out. But its a 16" rim, will that fit? Happy wrenching ;D |

Yes. Depending on the configuration of your bike and the size tire you go with. 130/80/16 should be a perfect fit with no mods. The only rub is, how wide is the GS550 rim? |

I actually prefer cast wheels/tubeless tires. ;D |

No kidding? With a hydraulic rear disk, it also had a hydraulic brake pedal too? Silly me. What was I thinking? ;D So like I said, ALL that you have to do is figure out how to mount the pedal, master cylinder/reservoir, brake light switch, fit the brake lines, and then figure out how to mount the brake caliper to use with the rear disk. Maybe the swingarm will swap. Should be easy. Guess I wasn't be imaginative enough :P |

Title: Re: Rear wheel/brake swap Post by barry68v10 on 04/17/07 at 18:30:54 Yeah, EVERYBODY seems to think "outside the box", thanks for thinkin' "in the box" for a change GREG! ;D :P |

Title: Re: Rear wheel/brake swap Post by verslagen1 on 04/17/07 at 20:49:23 Did some shopping today. Rears: GS550 rim, 16X2.5 recommended tire, dunlop 25.25 OD (going by memory) ls650 rim 15X2.5 recommended tire, dunlop 24.75 OD (going by memory) almost the same. biker2biker has a few gs550's, total cost should be less than $100. Fronts are the same. |

Yes, the sporty has a 16" on the back, and the tire is 130/80-16. But after seeing what you found from the GS I think that is the better route. I wish I had seen that before getting into the sporty side of it. |

Title: Re: Rear wheel/brake swap Post by verslagen1 on 04/23/07 at 21:28:26 I found a set of wheels for gs450. FRONT; J 19 X MT 1.85 | REAR; J 16 X 2.15 our stock wheels are: Front Rim: 2.15x19 | Rear Rim: 2.75x15 If you don't mind the narrow rims... price is not bad. ;D |
|
Title: Re: Rear wheel/brake swap Post by barry68v10 on 04/24/07 at 19:00:29 Will GS450 wheels fit? Are the spindles, bearings, and axles the same size? Or will they just "bolt up" after removing the stock wheels? |
|
Title: Re: Rear wheel/brake swap Post by verslagen1 on 04/24/07 at 20:47:37 Hold it, won't work! it has a 84 bolt circle. we're looking for a 100mm. Darn, well didn't want the narrow rims anyway. |
|
Title: Re: Rear wheel/brake swap Post by barry68v10 on 04/25/07 at 14:55:10 Well, I guess if somebody were doing a chain conversion anyway, an 84mm bolt circle would be no big deal... |
|
Title: Re: Rear wheel/brake swap Post by verslagen1 on 05/03/07 at 22:31:32 This is still all guess work cause I don't have a bone yard to pick through. But I've narrowed it down to a '81 to '86 GS550L. There are both disk and drum versions and sometimes I don't think people know what they really have. Several sources have said its a 16" rim not sure how wide. Probably 2.5" But the recommended tire is 130/80-16. I did check JT sprockets and it has the 100mm bolt circle. Already scored caliper and master cylinder for a buck + shipping. Finding a rim and disk for a buck is going to be harder. ;D |

Title: Re: Rear wheel/brake swap Post by Phelonius on 05/05/07 at 07:14:55 I think this swap would be an expensive cure for a non existant problem. On pavement in a straight line you should get about 80 percent of your stopping power from the front wheel. In which the dimunitive rear drum is good enough for the job. When braking in the special circumstances tha require more percentage of rear wheel brake, the very nature of the situation is such that you should be braking more gently anyway and using downshift as well. I would leave it as is . Phelonius |

Title: Re: Rear wheel/brake swap Post by Paladin on 05/05/07 at 10:34:17 If you do not want to crash into things you drive/ride within your performance limits. If you want to drive/ride faster you have the choice of extending your performance limits or exceeding them. The former allows you to go faster while remaining safe; the latter will lead to a collision. I recommend the former. |

Title: Re: Rear wheel/brake swap Post by verslagen1 on 05/05/07 at 11:30:08 If stopping was the only issue, I wouldn't bother. I am bothered by the squeeling. I can deal with cleaning the front. But the back is inaccessable. Plus, I like the sport bike look. The option for tubeless tires. ;D |
|
Title: Re: Rear wheel/brake swap Post by WD on 05/05/07 at 11:32:59 Huh, I'm going the other route, with a drum front... Check out all the older UJMs. Many had 16 inch rear wheels with discs. Some of them have dual disc 19 inch fronts with the same size steering stems. If you are adding a disc rear, ought as well go the whole route with new forks and duals up front. The bike would be fine with drums on both ends. It doesn't weigh anything. Discs? Overkill. -WD |
|
Title: Re: Rear wheel/brake swap Post by verslagen1 on 05/05/07 at 15:28:15 Yeah, you're right. I can lock up the rears no problem. Fronts, I don't try to. As I said, "if stopping was the only issue, I wouldn't bother" |
|
Title: Re: Rear wheel/brake swap Post by Paladin on 05/05/07 at 16:51:17 My next set of tires for Thumper wil be mounted on the not quite stock spoke wheels tublessly. I have my original rear wheel ready to take to Wheelworks, am in the market to borrow a front wheel. |
|
Title: Re: Rear wheel/brake swap Post by verslagen1 on 05/05/07 at 17:25:45 if I find a matching front mag wheel you are certainly welcome to borrow mine. and I'm somewhat near you. ;D |

Title: Re: Rear wheel/brake swap Post by justin_o_guy on 05/05/07 at 23:55:32 The rear rarely squeals anymore since I eliminated about 1/2 the surface area of the braking surface. It's also requiring a pretty serious application of toe to lock it up now. I can stop this thing a LOT quicker than I could before I did the rear brake mod. Maybe some of it is practice, I KNOW someof it is confidence, since I am not afarid I will lock the rear as soon as I touch it. If anyone is interested, I will explain the mod. |
