"Handcrafted Racing Machines"
"Alp hit 175.625mph on his Pre-Unit Triumph today. That's just
outrageously fast."
Paul d'Orléans - The Vintagent, Motosport Historian, Author/Writer
"That's damn fast! Amazing..I wish Jack Wilson was still around to see that."
Dave Howe - LSR Racer & Past Crew Member of Jack Wilson "Big D Cycle"
"That is one tough engine you have there !..."

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.
The 650cc "Pushrod Fuel" Triumph engine specs:
-
Thunder Engineering Triumph pre unit crankcases and connecting rods..

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.
