Yamaha HT-1 90 Motorcycle - Dual-Sport (1970-1971)

The Yamaha HT-1 90, available from 1970 to 1971, was a versatile motorcycle offered in both Enduro and Motocross (MX) trims. Powered by a robust 89 cc (often referred to as 90cc) air-cooled, two-stroke, single-cylinder engine, it produced 8.5 horsepower at 7,000 rpm. This model was designed for trail riding and light competition, offering a dynamic riding experience for its era. While the core engine displacement and horsepower for the Enduro models remained consistent between 1970 and 1971, notable distinctions existed. The Enduro model designation changed from HT-1 in 1970 to HT1B in 1971. A significant difference for the 1971 HT1B US model was the inclusion of turn signals, which were not present on the 1970 HT1 US model. Motocross versions, such as the 1971 HT1B-MX, featured performance-oriented engine tuning, achieving 14 horsepower at 9,500 rpm and utilizing a single-ring piston, emphasizing their racing focus.
