History of the Yamaha TR1

The TR1 was presented at the IFMA show in Cologne in the autumn of 1980 and went into production in 1981. Its engine was a four-stroke V-twin with the cylinders set at 75 degrees, displacing 981 cc from a 92 mm bore and a 69.2 mm stroke. The cylinder heads used overhead camshafts and eight valves in total, and induction was through Hitachi carburettors.

Outside Europe the same motorcycle was marketed as the XV1000. In the United States it was sold in a slightly modified form called the XV920, with a smaller engine. The model remained in production until 1983.

The TR1 is remembered as one of the large V-twins that established Yamaha in the cruiser and sport-touring market of the early 1980s, before the Virago and later Star models took over the role. Its clean, simple styling and big air-cooled-looking V-twin have made it a popular machine with collectors.
