Yes, I have a 300 kit on my 99 busa and that's big, and sucks for handeling, because you have to go a minimum of 8 inches over, like they said go with a 240 kit. They are up to a 400 kit so where does it stop. if you have $11,000 dollars for a 400 kit, then go for the biggest, I will never do another big tire bike, My 08 busa is almost done with the mods, but no big tire.
