Only reason they get stuck is because of the rider (that's me). They have a slower acceleration from a dead stop than a 2 stroke but in the long run can outrun anything. Last year we had lunch at Little Horse Lodge and did a high speed run across Green Lake afterwards. I passed a Crossfire 800 like it was standing still. I have a Cat.Jaguar Z1 while my wife has a Cat. T660 Turbo. I must say her sled can take mine in spite of my 1100CC. Drool Kiwi!
