Triumph Super Sprocket

Triumph Super Sprocket

Once in a while, we get a project that’s a whole lot of fun.

We fabricated a set of sprockets for a 1920 Triumph Model H just in time for this year’s Portland Maine to Portland Oregon Motorcycle Cannonball Race.

The 98 year old machine originally had a belt drive system with a bad habit of slipping in the rain. Our custom-made sprockets worked flawlessly for the 3,000 mile run and our client, Paul Warrenfelt, came in first in class, second overall.

Keep us in mind when you need custom design and fabrication. Especially if you have a project we can root for.
