18 inch rear wheel on an XS1100

Hey Deebs, I know Topcat did the swingarm mod years back. There was a thread about it, IDK if it survived the move from .com, I couldn't find it. There was a UK site where those fellas did mods like this, it's a shame all that valuable info got lost too.

Just an idea, there is more room to shift/shim the wheel over to the right side a bit. I wouldn't think with running a hack, the alignment with the front wheel would be quite as crucial.

I don't know if this will help or not, because photobucket ruined the pictures/

Thanks Phil & Bob. Very valuable info. I CAN be done and it HAS been done. Perfect. This is the wheel that will be modified to fit the XS11 hub.

Don't forget to leave access to the small screw on the back of the brake caliper, or maybe just leave the screw out.

Good point, Phil. While lowering the diameter to 15" I might have to machine the caliper in order to wrench it on or off. Might have to remove the wheel to get at the brake to change pads every so often. Not a big deal.

Another thing to think about is with the 850 drive mod, you are only using 2/3 of the driveshaft splines at the U joint due to the 16mm spacer you need. Might not be the best idea with the added weight of the rig. Who knows?

I think 3phase had a custom yoke welded up so the full depth of the drive splines could be used.

Phil, I am looking at the 850 rear drive modification to make up for the small diameter car tire. I read up on the subject and would definitely weld an extension on the universal joint. It's crazy to reduce the spline surface with that kind of torque pressure.
