Default tires

Does anyone know the affects of running a wider rear tire? I have a 2008 CBR 1000, and was thinking of running a 200 in the rear. Has anyone ever ran a 200 in the rear? And what about just changing from a 190/50 to a 190/55? I use this bike for the both street and track riding too

I have an '08 1000RR and this past summer I switched from a 190/50 to a 190/55. Other than slightly taller gearing that I corrected with a 520 conversion kit the only difference I noticed was the bike seemed to fall into a turn a little more quickly. The fact that my old tires had over 11,000 miles on them and a bit of a flat spot in the center may have contributed to the different handling.

I only do street riding.

Going from a 190/55 is awesome. It'll make the tire look narrower, though. Like Roadi said, the bike will fall in better and in some cases you'll even get better grip coming out of corners because the taller profile gives you a better contact patch when leaned over.

Running a 200 tire works if you're having grip troubles driving out of corners and you want to sacrifice a bit of entry agility as 1000cc bikes have the motor to break that tire pretty easily. A lot of race-spec slicks are offered in a 200/55 or 200/60 just for that reason. Be careful running a 200 tire, I'm not sure how wide the CBR1000RR wheel is, but I have a buddy who ran a 200 on his S1000RR to try to get a bit more grip out of corners on his track bike and he kept splitting the tire. That was with Metzeler tires so you may find better results with other brands.

Ok that's what I was wanting was the bike to fall into the corners a bit easier. I'm not too sure I'm going to a 200 in the rear, just wondering if anybody else had done and ran into some troubles.

Just started thinking about the front tire and what little I know about suspension. Say I switch the front tire from a 120/70 to a 120/60 the tire should have a more steep profile right? I mean the sidewalls are going to be shorter, but your still keeping the same width across the tread so I would think the tire would have a more steep profile. So if I went to a taller tire in the rear and then a shorter tire in the front this would affect the... rake... I believe that's what it is. This would shorten the rake and make the bike more responsive in the turns right? Would this be right?
