Triumph Trackmaster frame

Lindsay Brooke, Triumph Racing Motorcycles in America, Motorbooks 1996

  This Trackmaster frame was commissioned by Triumph in 1967 as an official Triumph replacement for a stock Triumph frame, it was constructed from chrome moly tubing by Ray Hensley of SonicWeld frame fame. They were stamped with a Triumph part number to allow it to be used as a "factory frame" as the rules then specified. Compare to a Harley XR750 frame below, these frames, unlike  roadracing frames, were intended to flex.
