I bought an old k5 gsxr 600 track bike that I'm racing in my first race at Road Atlanta. It came with a 200 Michelin on the back. I'm planning on tracking it at barber Monday, do I need to put a 180 on first? The tires are fine for a track day, but the size seems wrong. I don't think I could even get a warmer between the tire and swing arm hah. Is running a big tire on a 600 even a thing? My other bike is an S1000rr I've tracked a lot so I like a big tire to hammer on. Thanks!
Should be a 5.5" rim on the 600 (unless someone swapped a 1000's 6.0" rim on there), which isn't the ideal size for a 200 tire. However, if it's already on there, while it's not ideal, it's not un-safe. I'd run it and then pick up the proper tire after you burn up the 200.
Swap a 180/190 on it if you can. A 200s profile will be off. You will end up thinking about it all day instead of enjoying the track.
In a Michelin, we prefer the 180 or 190. STT should have some at the track. We'll be at Road Atlanta selling them. We'll still be offering the buy 2 rears, get a front free deal also. We'll be there late Thursday on through the weekend doing Michelin and Bridgestone tires.
