Vehicle Information
Husqvarna WR 250 Dirt Bike (1972-2013)
The Husqvarna WR 250 was a prominent two-stroke enduro motorcycle produced from 1972 to 2013. Renowned for its robust off-road capabilities, this model underwent continuous evolution throughout its long production run, adapting to changing performance and technology standards while maintaining its core identity as a versatile dirt bike. Over its four-decade history, the WR 250 saw numerous significant updates rather than distinct generational breaks. Early models (1970s) introduced new power plants and 5-speed transmissions, evolving from air-cooled engines with dual shocks and drum brakes to liquid-cooled systems with single shocks and disc brakes by the late 1980s. Major refreshes occurred around 1999-2000, bringing new bodywork, suspension components (Sachs shock), and engine internals (crankshaft, piston, clutch). Another substantial revamp in 2007-2008 introduced updated ergonomics, instrumentation, and premium suspension components like Marzocchi forks. The final years (2010-2013) continued with refinements such as Kayaba forks and improved exhaust systems, ensuring its competitive edge. While the primary trim remained the WR 250, minor variations like the WRK and WXE appeared during certain periods. Q: How can I ensure I select the correct parts for my Husqvarna WR 250?
