Grrr - his kawasaki has ample power to get it sideways. Power is not the issue, its riding style, and the power delivery of the bike, setup, etc. He came from a speedway background, so thats how he always rode.
Mini Me - brand new DR650, full staintune system, Laced 17" road wheels, airbox/filter mods, rejetted, geared down, new bars, strip weight, 2nd hand race tyres, suspension at both ends, should be fun. Only got 600k's on it, so its not even run in yet. I wont ride it too much.
One of the things i love about them, is that they are cheap to crash.
