Vehicle Information
Yamaha RT1 360 Motorcycle - Dual-Sport (1969-1971)
The Yamaha RT1 360, available from 1969 to 1971, is a classic two-stroke, single-cylinder, air-cooled enduro and motocross motorcycle. While specific details for 1969 are not widely documented, the RT1 360 was officially introduced in 1970, powered by a 351cc engine, often rounded to 360cc. For the 1970-1971 period, Yamaha offered two primary trims. The RT1 Enduro model, designed for both on-road and off-road use, produced 30 horsepower. In 1971, the more aggressive RT1-MX 360 motocross version was introduced. Equipped with a GYT (Genuine Yamaha Tuning) kit, it boasted 36 horsepower thanks to a ported cylinder and a larger 34mm Mikuni carburetor. The 1971 RT1-B model also brought improvements, addressing issues like starting kickback. Color schemes varied, with 1970 models typically black with yellow pinstripes, changing to black with red pinstripes for 1971. FAQ:
