ASYMMETRIC AERO

Alp’s first machines, including “Asymmetric Aero,” used no wind-deflecting bodywork, and ran in the Unstreamlined class. His first Vintage-class racer made 132mph, with an original Triumph rigid frame and all-iron 1950 650cc Triumph engine, running on gasoline. The “Asymmetric Aero” was the next development, using an aluminum cylinder head and stronger crankcases (still pre-unit), with the bodyhugging chassis that pushed his bike into the Class A “special construction” category. The Aero is tiny, to keep its wind resistance very low without using streamlining, and Alp started adding nitromethane to his fuel mix.

“With the nitro, my later engine probably produces more than 150hp at 160+ mph.” That “+” eventually became another 15mph, and the Aero retired with a recorded two-way average of 175.625mph, the fastest unstreamlined, pushrod-engine motorcycle in the world for all capacities under 1000cc.
