Vehicle Information
Honda CR85R Dirt Bike (2003-2008)
The Honda CR85R, a renowned two-stroke motocross bike, was produced from 2003 to 2007, though some 2008 models are listed, likely representing late sales of 2007 stock. It was powered by a liquid-cooled, single-cylinder, 84.7cc two-stroke engine, consistently delivering around 26 horsepower. Two main trims were available: the standard CR85R and the CR85R Expert (also known as CR85RB or CR85RII), which featured larger wheels, a longer swingarm, and higher seat for taller riders. The 2003 model year marked a significant evolution from its predecessor, the CR80, with an increased engine displacement, a stronger frame, and improved transmission. Further substantial refinements were introduced in 2005, including a new cylinder, piston, exhaust system, carburetor, and ignition for enhanced torque, acceleration, and durability. Subsequent years, like 2006 and 2007, saw mostly minor updates, such as sticker changes. Q: How do I ensure parts fit my specific CR85R?
A: Please use our year and edition selector to find parts guaranteed to fit your exact model.
Maintenance
| Component | Interval | Details |
| Engine Oil Change | 5 to 10 hours | More frequently for aggressive or race-level riding (5 h), less for recreational riding (10 h). |
| Oil Filter (Transmission) | With every oil change | The CR85R uses a transmission oil filter, changed with the engine oil. |
| Air Filter Service | 3 to 15 hours | Interval varies by model year and riding conditions (more frequently in dusty or muddy conditions). |
| Spark Plug | Regular inspection | Check and replace as needed to prevent fouling, especially for a competition bike. |
| Coolant | Check before each ride, annual replacement | Check level and condition frequently. Replace annually or more often under aggressive riding. |
| Top-End Inspection (Piston and Cylinder) | 15 to 50 hours | Interval varies significantly by model year and riding style (shorter for competition). |
| Bottom-End Inspection (Crankshaft and Bearings) | 30 to 100 hours | Interval varies significantly by model year and riding style (shorter for competition). |
Maintenance intervals can vary significantly by model year and riding style (recreational or competition). It is essential to consult your vehicle's specific owner's manual for the most accurate information.
