FXR wheels

[r1johnkt]

Hi, I have just bought a FXR and was wanting some info on the wheels to run slicks. I've heard that RS125 fronts will fit both front and back? or some guys are changing to wider rims 2.5 in front and 3.5 at the rear. What type of wheels are you guys fitting to your FXR's ? Hope someone can help. Cheers John

I just did that conversion on my FXR. I put ZZR250 rims on the bike. 2.5 front and 3.5 rear. The bearing size matches the FXR on front and back, so the axle will fit on both rims, however you will need to do a fair amount of machining in some places, make a new front caliper mount and make new spacers. Other than that the rims spread the slicks properly!

Thanks for the info! where is the best place to find such rims? Cheers John

I have done a conversion using the GSX250 GJ72 wheels. The front is a 17x2.50 and the rear is 17x3.00. I run a set of ex 125GP slicks (95/70/17 front & 115/70/17). Personally I think this a pretty good profile and not based on any fact I feel the 3.50 would be too wide.

As for ding the conversion there are a few different ways people have done the rear, here is the tread I started when I was doing it

As for the front, I replaced the whole front end cause my FXRs was crunched in a crash, and thats as easy as tighting up the stearing head.

Ohhh, and another few comments, the GSXR wheels arnt the lightest wheels in the world (actully there fugin heavy bastards) so that is a bit of a down side, and there seems to be a bit of a demand for them and the market price is higher than I would consider resonable

Ive just stated wrecking a 1989 GSXR250 but im not sure if i want to part with the wheels or keep them for myself!

Hi thanks for your reply. What sort of money would you be after? Can I give you a call? Thanks John

Isn't 3.50 the correct size for the slick to be properly spread? So you can use the entire width of the slick. That's what I was told and it would be an advantage to have a larger contact patch right? Correct me if I am wrong!

correct 3.5 inch is the right size
but 3 will do in a pinch
the old rs's where 3 and the new ones are 3.5

Oh yep cool. The slick I have on the rear of mine looks properly spread and handles fine.

I have always worked off the attached table. Manly because I have never found any other evidence that relates tyre profile to rim size.

Are you able to get to the edges of your rear slick with the rim you are running? What size slick do you have on the back? When I had my 2.75 rear wheel (stock FXR rear rim) with the slick (115), there was no way in hell I was getting close to the edges of the tyres going around corners! Unless I was to lowside. But with the slick properly spread on the 3.50 rim, I can hit the edges of the tyre now.

The 115 width 125GP slicks are suited to the 3.5" rim. There is no problem running them on the 3" rim, other than possibly losing a bit of ultimate grip on the side wall. I don't think you would notice the difference in buckets.

115, and yes using it right to the edge

When I had my 2.75 rear wheel (stock FXR rear rim)

Ur umm think you might mean 2.15

Ur umm think you might mean 2.15

Yup! You are right. 1.75 is the front and 2.15 for the rear. Oh cool so 3.00 is big enough to spread the slick, that's cool! Matt should be happy with his 2.75 he is chucking on the rear of his bike then.
