If you are in the market for a track-only race car, might we suggest the Griip G1. Though featuring double the wheels that we’re used to, this carbon fiber clad Formula 1000 cart is powered by a very familiar power plant: the Aprilia RSV4 superbike’s V4 engine.

The RSV4 engine on the Griip G1 remains fairly stock, though it uses a drive shaft, instead of a chain drive, as it would on a motorcycles. As such, it makes roughly 201hp in this form, though the real value of the Griip G1 is the weight of the vehicle, which tips the scales at 860 lbs wet and fully fueled.
