Hey Folks, I just got a 01 250R and I need new tires. The mechanic said the Pirelli Sport Demons don't fit right (rear is 130/90 instead of 130/80), but I keep reading that the Sport Demons DO fit and make a significant difference. Anyone know the real deal here or if there are other tires that work/ fit best? Thanks.
The 130/90 will raise the height on the rear of your bike a little bit, which will in turn change the steering geometry of the bike, which then theoretically make it turn in a bit quicker. It depends on your riding style, some people prefer quicker steering and some don't. As long as it fits and doesn't drag on any parts of your bike, I don't see a problem.
