Trackmaster Frames can trace their roots back to the 1960s, when Triumph Motorcycles approached Ray Hensley and commissioned the famed race tuner and engineer to build a handful of bespoke chassis to be used in competition. Henley’s earliest frames were chromoly steel units with much more race-oriented geometry compared to the stock Bonneville chassis of the era. In the years that followed, Henley further developed his frames into increasingly purpose-built structures specifically made to go racing, helping to create a market for them along the way.
Trackmaster is still in operation today, headquartered in Valencia, California. According to the elite chassis producer’s website, it takes anywhere from 10-20 days to churn out a single frame, depending on the complexity and level of customization for each job. The 4130 chromoly racing frames start at around $3K (for non-nickel-plated, sans oil-in-frame), and run up to around $4.5K.
This particular example is a 1970 Triumph Trackmaster T120 Bonneville that’s been thoroughly customized, and given a few upgrades such as Ceriani forks and disc brakes. More than half-a-dozen one-off brackets and mounts were created specially for this build, along with custom machined aluminum velocity stacks and intake manifolds. The engine has also received a top end rebuild, as well as a new cam, and a new clutch was added too. According to the owner, this example has been “meticulously maintained” by a Brit bike expert, and is in pristine condition. The bike is also wearing a fun little “TRQMSTR” vanity plate.
