Put new set on today, front and back and the busa feels like a new bike. I set a line and the bike stays on it, like an amusement park ride. The other tires, always making corrections and changes, sometimes out right slides. A grin from ear to ear I say. I know they will only last 3-4k miles but I don't care. I figure what's $400 a year eh? For glue tires. Probably good for the track too. My goldwing touring tires lasted 8k miles, but had lumps on the rear and the front woo woo'ed in curves., ha ha new word and probably needed changing at 5-6k anyways, so no big deal on the pirelli's needing at 3-4k. I also went down a tooth on front sprocket and that made a big difference too, pulls harder, like it didn't pull hard enough already. I just cannot believe the difference from oem tires, try it guys, you won't be sorry.
