up .5

I have looked at a lot of internet sites and have no clue where to buy rims for my cbr250r. Also... what measurements do i need to know? axle size? bolt pattern? I wanna keep the stock tire sizes.
I need a site like tirerack.com but for bikes.

If you do find something that fits other than the stock part from Honda, which I doubt you will yet, I would go up .5 inch ft and rear which would be 3.25 front and 4.5 rear so that you will be able to have a better selection of tires. You could then fit 120/ 17 front and 150/ 17 rear.
