GSXR750 REAR WHEEL SWAP, 160/60/17 TYRE INCLUDED

Find out what manual you think is the best. Let the world know (and don`t hesitate to give usefull tips). Thanks!

Joris, yours seemed much more complicated to do than the one KEn suggested and has done. Only problem is finding the wheel but otherwise its a simple swap I'd even consider doing. I read yours when you did it and it was way more than I was willing to do, seemed much more involved...just my $0.02.

Glad we've got more than one way to do it though...when I get around to it I'll probably also link that page to yours if you don't mind.

The problem is when you install a 160 tyre you need to do even more. The first part of my explanation is pretty much the same, but the second part (to create even more space to mount the 160 tyre) is the complicated part. I do agree mounting a 150 tyre is much easier.  But hey, we all want to go on the limit.......

The only difference I can see (assuming a 150 tire) is that you installed a modified pipe inside the wheel spacer between the bearings to make up the difference in axle diameters. Ken did not; I guess the bearings support the axle completely in the OEM configuration meaning you wouldn't need that pipe you installed...this step in particular made it seem like a lot more work than I was willing to do, seemed like higher tolerances were required or something.

But I also added washer between the rear cush drive and the sprocket. And how about the washer between the cush drive and the wheel. I did a lot more, I think.

wasn't all that in order to fit the 160? Otherwise, Ken's method is even more simple.

The article is dead on. You have to have the GSXR spacer and shim it to the diameter of the GS axle. The shims don't have to be fancy or even full length, just hold the thrust spacer in location.

I bent mine up from sheet brass, one on each end about a 3/4 inch wide.

As I recall, if you use the GS spacers on the sprocket side you end up in proper alignment. I coudn't get the GS Caliper bracket to work at all though. I made one from scratch and got the swanky under slung thing out of it.

I'll post some pics. It is a good mod. If you can find the rim cheap it is even better.

For the record, I am running a 160/60 now, the next tire I buy will be a 150/60. If the chain get even a little loose or out of alignment it eat the edge of the tire. I really doubt any of us are riding off the edges of 150/60's.

Get some parts and a file and let do it.
