Those Aprilia's are twins right? What's the torque difference like compared to the single cylinder Husq's? Both 450's too right?
The Marlboro is my brothers old bike, he had two indentical ones for wet and dry races and were SXV 450s.
The Monster is his new bike and is an SXV VDB (Van den Bosch Replica). Awesome bike and not many in this country.
Not ridden one in anger, but they sound amazing and are very revvy for a twin.
Here's a vid of one of his races.
