Vehicle Information
Honda CR250R Dirt Bike (1978-2008)
The Honda CR250R, a legendary two-stroke motocross machine, was produced from 1973, with the "R" designation appearing in 1978, until its final production year in 2007. This page covers models from 1978 to 2008, all featuring a 249cc liquid-cooled engine. Throughout its lifespan, the CR250R underwent numerous significant evolutions in its engine, chassis, and suspension. Major generational shifts include the introduction of an all-new frame and suspension in 1982, a completely redesigned chassis in 1990, and an all-new CRV composite racing valve engine in 1992. Honda pioneered an industry-first aluminum chassis in 1997, followed by a second-generation aluminum frame in 2000, and a third-generation chassis with a new electronic power valve engine in 2002. These continuous updates ensured the CR250R remained at the forefront of motocross technology. Q: How do I ensure I select the correct parts for my CR250R?
A: To guarantee a perfect fit, please use the year and edition selector at the top of this page.
Maintenance
| Component | Interval | Details |
| Engine Oil and Oil Filter | 5-10 hours (aggressive riding) or 10-15 hours (recreational riding) | Replace filter with each oil change. Intervals vary by year and intensity of use. |
| Spark Plug | Approximately 30 hours | Inspect and replace periodically to maintain optimal engine performance. |
| Air Filter | 5-15 hours (depending on use) or after every ride in dusty/sandy conditions | Clean and oil regularly. Inspect for damage. More frequent cleaning is required in extreme conditions. |
| Coolant | Annual inspection; annual or biennial replacement | Check hoses and clamps. Older models (e.g., 1978) without an overflow reservoir require careful filling and air bleeding. |
Maintenance intervals can vary significantly by model year and riding conditions. For precise information, always refer to your Honda CR250R owner's manual.
