Yamaha TY80 Dirt Bike (1974-1975)

The Yamaha TY80, a trials-styled motorcycle, was produced by Yamaha Motor Company from 1974 to 1984, designed for younger or beginner riders in the trials world. For the 1974 and 1975 model years, the TY80 featured an air-cooled, two-stroke, single-cylinder engine. The 1974 model (TY80A) had an engine displacement of 72cc or 74cc and produced approximately 4 horsepower. The 1975 model (TY80B) was most commonly cited at 73cc (sometimes 72cc) and developed around 4.4 horsepower. These slight variations in displacement and horsepower between sources likely represent minor adjustments or different measurement methods, rather than a substantial engine redesign. Both model years featured a four-speed, foot-change manual transmission. The TY80's engine was based on the GT-80 engine. There were no significant mid-cycle generation changes or major engine overhauls reported between 1974 and 1975. The core design remained consistent. The TY80 was primarily offered as a single model, with the TY80A (1974) and TY80B (1975) designations indicating the model year rather than distinct "Sport" or "Deluxe" trim levels. FAQ:
