I change the oil every 3500 on mine because I do a lot of cold, wet miles, and when it's not cold and wet I occasionally ride like a bit of a tw4t. If I did a lot of motorway/steady straight line shoite I would stretch it out a bit.

It's a matter of opinion, a lot of people say they can feel the difference in the gearbox when the oil is getting a bit old, and modern oil is surely good enough to last a fair while.

Bandits are alright if you stick a GSXR750 top-end on them, but meh.

If you want a low seat, and something a bit different, what about a cagiva raptor?
