GSXR rear wheel bearings

Hi guys,

great informative site here, I have been reading an awful lot to learn prior to posting.

I have trawled the forums but found no info on GSX1100 (1982) to GSXR1100 (1993) rear wheel bearing spacers. I understand the bearings will fit over,but what about the middle spacer?

I have a GSXR rear wheel (5.5 inch) sans bearing and spacers, and just want to check if the GS gear will swap straight in.

With thanks

Ed
 
At least in my case because of the 700 having a smaller diameter axle than the GSXR I had to use my stock bearing support with an extra bit of length to match the GSXR support length. I simply epoxied the extra material to the support to hold it in place. If your axle is the same diameter as the GSXR axle then use the GSXR bearing support.

I made the same swap on my '82 1100E. The wheel bearings on the GS and GSXR are the same. The only difference is the grease seal. The one on the GSXR hub is larger on the inside diameter than the GS (outside diameter is the same). Swap for the GS and you can use the GS spacers for a perfect fit. There are other issues with the chain and rear rotor/caliper that need to be considered before you can make the conversion work. Unfortunately it's not just a swap of the rear wheel itself. Tons of threads on this issue throughout this website. Study all of them.
 
Hi Billy and RJ,

thanks for the reply.

I have studies alot on here and pretty much ascertained you need the GSXR rotor, brake hanger, caliper and torque arm.

I am using hayabusa rotor, with 02 GSXR caliper and torue arm mated to a GSXR1100K hanger (which is good for a 20mm axle). was planning to use the GS sprocket carrier and narrow the spacer on sprocket side 5/8".

I am going to make or buy a 5/8" offset sprocket for the front too to clear the tyre. (170 or 180 tyre) and 530 chain of course.

...Just wanted to make sure my GS wheel spacers were good to use as I bought a NOS GSXR rear wheel which is devoid of any bearings, spacers or seals.

I will post pics of my progress, all ready is a GSXR1100 1995 front to go on. Some of my fork length and diameter info conflicts with some on here, but will post only after I know it all works. the length of fork I am using has no issues, I also chose to put risers on my top yoke rather than use clipons.

great site, I am impressed with the professionalism of work, pride of ownership and true comaraderie found here.

Cheers

Ed
 
that's a 18" rear wheel, with the 5 bolt sprocket pattern correct?

You might want to make sure that diameter wheel will fit okay, especially if you plan on lowering it some

It's a 17" wheel. The 750 got 17's in '88 and the 1100 in '89.
 
I was able to use the regular (non-offset) sprocket up front. All I needed to do was to shim it away from the motor with large hardware store washers. The outside face of the sprocket is even with the end of the splines on the output shaft so there is still full contact between the two. Using my chain alignment tool I was able to determine that the chain was straight. Visual inspection of the rear sprocket and chain shows that the sprocket is riding dead center on the chain roller as well. Just use the GS sprocket carrier and you're in great shape.
 
Oh yeah, one little thing I neglected to mention. The washer that you bend onto the sprocket nut has to be removed in order to get the sprocket all the way out. There are 2 or 3 bolt holes on most of these sprockets that flank the bore in the center. I tourqued down the sprocket nut to where the flats of the nut lined up with those bolt holes. I then took 2 cap screws and ran them down into the holes next to the sprocket nut. They now keep the nut from loosening. I had to grind the heads down enough so that they would fit into the gap but it works. If you haven't converted your chain/sprocket combo yet then it may just be easier to get the offset sprocket. I already had the 530 setup with the older rear wheel and was simply too cheap to scare up another sprocket.
 
Hi BRVeagle,

it is a 17 inch wheel as Billy mentioned. thx.

I dont want to lower the bike (any more than necessary), justt give it a good look and choice of nice rubber.

Hey RJ,

good idea using the two holes for some lock bolts. I was wondering how to lock the nut down.

if shims work for you that's cool. I may need to go that route too. I have checked out Arnout's way of making an offset sprocket, as well. looks pretty good, I have a decent MIG welder at home, just need somebody to turn out the middle of the sprocket.

I am trying to contact AFAM Japan for an offset sprocket as no dealers here in Australia seem to have an account. I was trying to source on through "Chain Gang" here.

Cheers

Hey Guys,
When I had the Dealership press in a set of GS700 bearings in the 92 gixer rims, I found out he did not change the spacer between the bearings, obviously leaving some space, Is this going to be a problem?

More than likely. You need the bearing support to keep from putting the bearings in a bind.

Ed Ron Angel in Melbourne is the Oz importer of AFAM sprockets.

thanks Dink, will bear that in mind.

AFAM since replied and are going to ship direct to me.

if something goes awry in the translation shall use Ron Angel.

Cheers

Thanks Billy. My heads up my arse, if the support was from the Gsxr then it would be the right length, just not the right ID. I can't think of that causing a problem.

The spacer rests on the inner race. If it still does that you are ok. If it rests on the bearings then you will have a problem.

Very true. Maddawg, you need to either have the proper support machined to match the GS axle or use the 700 support with additional material added to it to match the length of the GSXR support. All I did was take a short piece of hydraulic jack handle and epoxy it to the 700 support. It was the correct id and you are only trying to keep the bearings out of a bind. The GSXR support could become misaligned and put the bearings in a bind.
 
Your right, better to do it right the first time(well tech 2nd) then to find out too late. Thanks guys
