Vehicle Information
Yamaha CT1 175 Motorcycle - Dual-Sport (1969-1971)
The Yamaha CT1 175, produced from 1969 to 1971, was a popular enduro motorcycle known for its versatility on both road and trail. All models from this period featured an air-cooled, two-stroke, single-cylinder engine with a 171cc displacement, consistently rated around 15.6 to 16 HP and 16.2 N·m of torque. It was equipped with a 5-speed transmission and Yamaha's Autolube oil injection system. While the core engine remained consistent, each year featured a slightly modified model designation (CT1 in 1969, CT1B in 1970, CT1C in 1971). The 1971 CT1C model specifically incorporated a "new five-port cylinder" designed to significantly improve engine efficiency and power output. FAQ:
