Honda CRF 250X

Skilled off-roaders seek a bike that offers an ideal balance of power and size, performance and handling. That’s why we built the CRF250X.

Based on our popular and podium-friendly MX racer, the CRF250X is powered by a four-stroke Unicam® engine modified for optimum off-road riding. We’ve also specially-tuned the suspension for the trails, and given the rugged transmission wide-ratio gearing to handle whatever conditions you come across.

Then there’s the electric starter that puts you on the fast track with the push of a button. So take a look at the CRF250X. We think you’ll like what you see.

CRF250X - trail ready

When off-road competition shifts away from the motocross track to enduro, hare scrambles and cross country courses, motorcycle priorities also shift. Canadian forests are characterized by tight single-track trails with more than their fair share of roots and rocks which means out there, agility and compliant suspension become essential attributes. The CRF250X is well suited to the Canadian wilderness with its unique Unicam engine and its trail-tuned suspension. The Unicam engine's single overhead-camshaft offers lower reciprocating mass and a lower centre of gravity than traditional double overhead-cam designs, resulting in superior manoeuvrability and agility. To make sure riders can take full advantage of this competitive advantage, the CRF250X is fitted with sophisticated suspension front and rear that is tuned with just the right amount of flex to allow the wheels to track true over the almost continuous small obstacles encountered on the trail. The suspension is equally adept at handling the bigger obstacles too; with generous suspension travel to soak up logs and rocks while the rubber-mounted aluminum handlebar reduces shock to the rider. The quiet exhaust system with spark arrestor should breeze through pre-race tech and the lightweight electric start provides a better chance at the holeshot in those "dead engine" starts. Light, agile, compliant and backed by Honda durability and reliability, the CRF250X is ready to race.

Dominate in the Dirt.

Along with its powerful and lightweight engine, the CRF250X has dozens of smart features like works-type front and rear brake discs, a narrow fuel tank that's easy to move around, and an 18-inch rear wheel for superior tire selection and traction. In short, all the attention to detail you'd expect in a Honda.

•Lightweight, compact, internal auto decompressor system provides superb cold-starting and hot-starting operation.
•Forged 12.9:1-compression slipper piston is lighter than a conventional design, revving quickly while maintaining excellent cylinder sealing and high-rpm power.
•Swingarm features a dual-axis, double-taper design with a large cast-aluminum cross-member.
•240 mm wave-style front and rear brake discs reduce unsprung weight.
