Well - in standard trim they steer slow, and feel like lard. Once they are lifted up a bit and the suspension firmed up they are awesome handling bikes - it's basically a 888 frame.
Brakes - they are good standard but with decent pads in them, like performance friction, they are simply AWESOME!
The engine is ok, torquey out of corners but it's still slow. Slow, slow, slow .... but with the good chassis setup, nice brakes etc you can still hustle them around in a respectable time.
