Triumph Street Tracker:  Builder Interview

(Answers by Bill Gately of Bonneville Performance.  Highlights by us.)

• Please tell us a bit about yourself, your history with motorcycles, and your workshop.

I am 67 and have been passionate about motorcycles since I was old enough to climb on one. I also have a passion for the Triumph brand and flat track racing.

This bike is a ground up build – the chassis is mine – I designed it in 2005 and for the past 11 years I have owned and managed a Triumph powered Grand National Flat Track Team in the series now known as American Flat Track.

From 2011 through 2016 I was the factory team for Triumph. I have taken off this year to develop a new Grand National Race Bike using the new Triumph water cooled twin. This too will have a proprietary chassis as well as an engine completely re-engineered to compete on the track.
