2001 | RM250

Newly designed motocrosser with a superb balance between powerful road handling and controllability

RM250

The engine and chassis of the RM250 were almost completely redesigned to realize a sweeping reduction in weight, higher power, and greater torque, creating a superb balance between road handling and controllability. The new 2-stroke engine with a newly engineered piston reed valve is 1,133 g lighter and 21 mm shorter than the previous model. This engine boosts torque in the mid-rpm range, lifting the rideability of the bike onto the next level. Although the semi-double cradle frame of the previous model was retained, the specifications and design, including the rigidity balance, weight distribution, swingarm, suspensions, and geometry, were all completely updated to increase rigidity and realize a tremendous reduction in weight. The result is an ideal motocrosser that creates a winning balance with its new high-performance engine.

2003 | RM250

Motocrosser with a wider powerband and smoother output characteristics

RM250

The new RM250 features a new engine that combines low- to mid-range torque with high-end power thanks to features such as new cylinder ports and an exhaust valve control system that were developed based on actual racing experience. Course following performance and traction under a wide-range of riding conditions were enhanced by the adoption of a highly tuned chassis, as well as by the refinements applied to the superbly balanced suspensions, brakes, and other features.
