I've had my 636 for almost two years now and was thinking of moving up. Since I live in the Valley and most of my riding is highways I was looking toward the litre bike. Don't get me wrong I love my 636 and can ride it with the best, and I have the knee pucks to prove it. In fact I may even try the next track day.
Two weeks ago a friend of mine lent me his zx10 and it got me wondering if I should make the jump up. It's so much more fun to ride on the highway. Opinions?
