Brough Superior and Aston Martin are releasing a track-only version of the AMB 001, the AMB 001 Pro. The AMB 001 Pro uses the same chassis but with a 25% power increase to 225 horsepower from the “base” AMB 001’s 180 — giving the bike an F1-like 1.28 power-to-weight ratio. The power increase is possible thanks to a new V-twin engine design, fully machined from an alloy billet. A front spoiler and wings increase downforce, and a blade at the front creates a wind tunnel over the rider for decreased air resistance and a rear fin to stabilize the bike at speed. All 88 units of the AMB 001 Pro have already been sold. But you can always check our list of the fastest motorcycles in the world.
