The year 1963 saw major changes for the Triumph 650, namely in the engine bay, where crankshaft, transmission and primary-drive components were all combined in the same cases, creating a so-called unit-construction powerplant. A redesigned alloy cylinder head featured increased fin area, and an extra stud was added between the cylinder bores to provide better gasket sealing. To carry the new engine, a completely redone frame was designed with strengthened swingarm pivots and a single front downtube, quelling the vibration and iffy high-speed handling exhibited by the previous duplex frame. While the 1963 models were substantially improved, Triumph made sure former styling cues remained, and the new bikes looked little different and every bit a sleek as before. The unit-construction engine presented a cleaner appearance and was more integrated within the new frame. By now Triumph was aware that the sun shone more brightly in the U.S. than in rainy old England, so paint quality had improved dramatically. The two-tone paint jobs used a silver base coat under the darker colors to give them more of a visual pop. The matching-numbers TR6SS seen here proudly wears its correct Flamboyant Regal Purple top color, just one aspect of an exacting nut-and-bolt restoration undertaken in the mid-2000s by renowned marque expert Bill Hoard, including a full engine overhaul to standards exceeding factory build quality. Maintained in show-worthy condition as part of a private Florida collection for the past decade, previously the bike was on display at the Motorsports Museum of Orlando.
