Can i put a wider rear tyre on a Suzuki fxr 150?

[atom608]

I got a 2002 suzuki FXR 150 and I am wondering if its posible to fit a wider rear tyre on the rim? the dimensions of the tyre I am running now is 100/90-17, is it possible to fit like a 130 on there?

....uh, why?

[EJK]

Because FXRs are too powerful it'll need more rear grip?

[Tazz]

Get yer mums fabric ruler out, have a squiz and take some measurements for yourself man. I doubt it.

Swingarm and chain clearance are going to be an issue. A wider tyre may be taller, which is again, going to affect clearance.

You're going to alter the handling of the bike as well. A larger tyre will likely slow the turning ability.

This will probably sound stupid but I have been doing research and I hear wide tyres are alot more stable at high speeds, Most of my riding is on highways at the speed "limit" of "100". also on alot of roads where I live there are these weird groves like rubber tar seal and when I go over them the wheel seems to get stuck in it and causes the bike to wiggle around alot, probably because the wheel is so thin. also I hear the bike will be more stable with a wider rear tyre around corners because it will have more of a contact patch to grip on, plus I just absolutely hate, hate, HATE the look of that tiny little 100width tyre, the bike is light enough so even with a wider rear tyre it will still flick into corners fast anyway. Not asking for an opinion, im asking if its possible and from another thread I heard a guy used a 130/70/17 rear tyre on his fxr but I was not sure if he had customized it or not.

Doesn't sound stupid at all. Not sure about size 130 but I had fit Bridgestone BT45 size 110 on my old FXR. Felt a tad more planted and stable around tight corners too.

did you still use a 80/90-17 front or did you put on a slightly wider one too?

I don't remember changing the width on the front. But instead of increasing the width I put stickier BT39SS.

I don't think a 130 rear tyre would work well, the rim is too narrow and it will pinch the tyre into an undesirable shape. Many FXR bucket racers run RS125 slicks on their bikes which are 95 in the front and 115 in the rear. Myself and a few others use 120/70/17 rear slicks as they are easier to find, although that size does pinch the tyre together a bit.

The 'wiggle' in grooves is often called tram lining. It's a little bit shit.
Have you tinkered with your tyre pressures? What do you run them at now? That alone can make huge difference.

At 140+ it would make a difference. At your speed it won't matter much.

Wider tyres also share the same issues. Tar seal lines are just bad.

I hear the bike will be more stable with a wider rear tyre around corners because it will have more of a contact patch to grip on
Yes, but it must be a match to the rim width. Fitting oversized tyres on skinny rims won't give you that.

I just absolutely hate, hate, HATE the look of that tiny little 100width tyre
This is the primary reason, isn't it? 120 vs 100 won't make much difference though.

It is possible, technically. Just not a good idea. Won't handle well enough.
Unless you change the rims.

Or get an oldie but goodie CBR250RR.

I usually just leave it at what feels like around 35PSI for the back and my guess would be mid-late 20ish psi in the front.

yeah I sort ofknew 130 would probably be too much for it but just looking for something a bit wider, my rear is at around 40% tred left, il try to find something around 115-120 next tyre change
