Vehicle Information
Yamaha YZ250 Dirt Bike (1974-2026)
The Yamaha YZ250, a legendary two-stroke motocross race bike, has been a dominant force on tracks worldwide since its introduction in 1974 and remains in production through 2026. This iconic model has continuously evolved, adapting to the demands of competitive racing while maintaining its core identity as a high-performance 250cc two-stroke. Over its extensive lifespan, the YZ250 has undergone several significant transformations. Initially, from 1974 to 1981, it featured an air-cooled engine. A major technological leap occurred in 1982 with the introduction of a liquid-cooled engine and the innovative Yamaha Power Valve System (YPVS). Further engine refinements in 1999 adjusted bore and stroke for improved low-end torque. Chassis advancements were equally crucial, notably the shift to a lightweight aluminum frame in 2005 and the adoption of KYB Speed-Sensitive System (SSS) front forks in 2006, which are still highly regarded. Beyond the standard motocross model, Yamaha introduced the off-road focused YZ250X in 2016 and offers special editions like the 70th Anniversary and Monster Energy liveries for 2026.
