race rubber

Know this subject has been coverred a thousand times. But, been racing on and off with 800ss with stones bt003's 120/180 with some success. Talked to someone that suggested 125/165 slicks. At the bridgestone site they are listed under 250 gp bike size which horspower wise is more or less what the 800 is getting. My bike dynoed at 79.

Any expereince with these tire sizes? Easier turn in? Grip? Durability? Larger contact patch? etc.

thanks,

I don't think a 165 tire is going to fit your rim. You really need to match the tire size on the stock rim which was designed for a 180 rear tire. The 250 GP bikes have something like 4.5 inch rims which were designed for the 165 slicks.

Remember that any change in tire brand or size it is going to impact ride heigth and handling...

actually according to Bridgestone's site:

I can run a 165 250 gp slick on a 5.5 rim, which is what I have. Still have to check the front. My geometry is already thrown off after switching from Michelin to the Stones bt-003s. Taller profile both front and rear. Don't know how the slicks profile would change even more. Might have the guy who originally set up the geometry take a look next spring. Course it always comes down to $$$$.
