oh yeah, im sure that i haven't. and you just wont on the streets. but i think you can feel more power out of the 1000 while staying within the rules of the road. i totally agree a 1000 can get me or anyone into trouble. anyway, i think ill try new sprockets here in the coming weeks and see what that does for me. I'll probably go test ride a cbr1000 too just to see what thats like.
