Yeah... I'd just be always worried about the highside. There's a good vid on Youtube somewhere of a guy drifting a Kwaka 9 too.
I remember years ago watching Eddie Kidd ripping up the streets on his YZ250. At that time I was doing a lot of riding and was a passable club level dirt tracker. So I got my DR250 out of the shed and went for a ride round town in the rain, trying to slide all the corners. Did OK for a while but just could not get knobbies to drift smoothly. Eventually dumped it in out front of Woolies
Realised then and there that I haven't got IT.
