Hello, you say 600cc is plenty
plenty for now, but you may find out as i did that a 600 soon becomes slow, i part ex'd mine for a fireblade, i had that up to 157 on the A14 going past Bury st Edmond's, and nearly hit the back of a bmw that pulled out on me, (what a rush who needs drugs) then the repo man came so i got a 916, that was fun till my wife said "i'm knocked up" or something like that, so that went as-well, i hope you have many many happy hours zooming along the highways
