It all began during a simple conversation between two friends about Triumph’s legendary Grand Prix race bikes.

During a discussion with Bob Klassen about how much we both admired the famous Triumph GP race machines built between 1948 and 1950, I pointed out that I had a rigid Triumph frame and parts of an all-alloy 500cc T100 engine sitting around. Bob mentioned he had a Triumph fork, a BSA Gold Star 8-inch front hub and a Borrani alloy rim, a pair of Amal carburetors with a remote float, a magneto, and parts of a gearbox. What happened next surprised both of us: We decided to pool our parts, share the expenses and build a “tribute” Triumph race motorcycle.

As a paraplegic, there’s no question that I’ll ever be able to ride the machine — I won’t. But our cooperative efforts returned components that were sitting in our respective Calgary, Alberta, Canada, garages back in service. But before we learn more about our project, let’s go back to the beginning for some background about Triumph GP racers and some of Triumph’s other speed efforts.
