Vehicle Information
Yamaha YZ360 Dirt Bike (1974-1975)
The Yamaha YZ360, produced from 1974 to 1975, was a significant motocross motorcycle renowned for bringing "works bike" features to the public. Both the 1974 and 1975 models featured an air-cooled, single-cylinder engine with a nominal displacement of 360cc, though some sources indicate 351cc for the 1975 YZ360B. These powerful two-stroke engines were capable of around 30-40 HP, making them highly competitive in their era. The YZ360 was offered in distinct trims each year: the 1974 YZ360A and the 1975 YZ360B. The 1974 YZ360A was characterized by its silver finish with red stripes (yellow for the US market) and a fuel tank secured by straps. It incorporated advanced lightweight components like milled aluminum, a magnesium clutch case, and external reservoir shocks. A major advancement arrived with the 1975 YZ360B, which introduced the groundbreaking Monoshock rear suspension, a first for the YZ series. This model also marked the last year for the "Strap Tank" design. The YZ360 line was discontinued after 1975, succeeded by the YZ400 in 1976. FAQ:
