Tire sizes
 

Hi there , I have a honda cbr 600 FL ( hurricane, jelly mould type) , what I'd like to know is it possible to fit larger tyres to the bike ?.It comes as standard with a 110/80/17 on the front and a 140/80/17 on the rear. Would it possible to fit a 120 on the front and maybe a 150 or even a 160 on the the rear ??

Thanks Eddie

it comes stock with at 130 on the rear. Most people put a 140 on as the 130 is tough to find. No, you wont squeeze a 150 or larger on the rim. Cant fit a 120 on the front either. You are stuck with bias tires. And in those sizes. I know from exp that that same bike with dunlop 501's will hold up just fine with newer bikes in some twisties.

cheers for that just like you said really these tyre sizes are hard to come by at good prices

you can go up to 150 on the rear. i am using a michelin pilot road 150/70/17. works just fine with no chain or swingarm clearance issues. no rear handling ills. i've been using 150's consistantly for the past several years without any problems. at 160 the tire will still fit, just barely between the swingarm but will crown causing the rear to be unstable.

the front doesn't take a 120 very well as the rim is a bit too narrow causing the tire to crown. it will fit, but your turning and side to side transition will suffer. i run a bridgestone bt-014 110/70/17. side grip is very good but you will probably hit hard parts before ever getting the bike really cranked over.

So the 150 fits on the stock rear rim with no troubles??

also, would you recommend the bridgestone or dunlop tire in that size?

RE: tyre sizes
 

did you see the link to the pic. no fitment problems. 150 on a 3.5" rim is really the max without changing the profile shape of the tire.

i could be wrong, but the dunlop only has that size in the GT501 model. good tire but it is a bias ply tire. i had used a 501 in the past and it is a good tire especially for commuting. a good tire up until you push real hard like say if you're doing track days or running real hard through twisties all day long.

i have no idea about bridgestone rear. the bt014 front that i am running now is very good. a radial tire. and the michelin rear that i am running is also radial.

Maybe i'll try those michelins. I just realized that the guy i bought the bike off of was running a 110/80 on the front, and a 130/90 on the rear.........no wonder i can feel every crack and groove from the front end....
So basically i need new tires anyway...

RE: tyre sizes
 

well, 110 and 130 are oem stock sizes.

i still run a 110 front just in a lower aspect. but the rear i just went from 130 to 150. i don't feel every crack and groove from the front. maybe it's just me. i prefer running the 110 because i like the neutral feel and quick turn in and side to side transition.

the michelin rear is nice. excellent grip and decent warmup time.

RE: tyre sizes
 

do you recommend bias or radial?

RE: tyre sizes
 

Your bike will need bias. The chassis harmonics wont take a radial tire very kindly. Also, a radial tire of a given width, needs a wider rim to fit properly compared to a bias of the same size. A 150 radial wont fit like a 150 bias.
