We race mainly in two engine classes "V" vintage, "P" pushrod and in two body/frame classes "A" Special Construction, "M" Modified Production.
Both vintage and pushrod engines are based on 650cc pre-unit Triumph engine & gearbox combinations. The main difference is that we are allowed to use aftermarket crankcases in the pushrod classes.

"Alp 650 Triumph"
The concept is an ‘imagined alternative factory design’ from the pre-1956 era; a period-correct design study that might have been produced at the Meriden Triumph factory for the American market.
Alp Racing & Design provides a glimpse into a possible past today, with a street-legal racing machine built for the American market. It’s a new-vintage Triumph that’s simultaneously strong, fast and classic.

Concept Design & Build
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.
