Click here for an VINData Motorcycle History Report on this 1966 Triumph TR6. Additional photos are available here for your perusal.
After its successes with the T110 and TR5 Trophy, Triumph debuted the TR6 Trophy in 1956. Specifically developed for the US market, it featured the same 650cc engine as the T110 along with the two-into-one exhaust, 7-inch front brake, and quick-detachable headlamp of the TR5. In the following years, Triumph made incremental improvements — like adding a larger 8-inch brake and a stronger steering head — until it implemented unit construction for all of its 650cc models in 1963.
Not content to stop there, Triumph continued to make still further changes to the TR6, raising the compression ratio, switching up the brake shoe design, and introducing the infamous Amal Concentric carb.
Today, the TR6 remains one of the most iconic Triumphs of the 20th century. Between its competition pedigree and its appearance alongside Steve McQueen in The Great Escape, the bike has cultivated quite the cult following.
This example is VIN: TR6SRDU28892 with matching engine number: TR6SRDU28892. The seller purchased the bike at a Mecum auction in 2017, and states, “I have always loved 1960s British motorcycles, and since the early 1980s I have always had at least one in the garage. I fell in love with the patina on this one and brought it home, brought it back to life and enjoyed it. But I have recently acquired another vintage Triumph that needs the same attention, and I have too many other motorcycles and projects in the garage. It’s time for this lovely machine to have a new home.” 
During his ownership the seller has covered approximately 600 miles. The odometer shows 7,269 miles.
