2017 Honda CRF250X

Track and trail champion.

Every off-roader wants the light weight, crisp handling, and razor-sharp performance of a racebike. But everyone also wants it to be easier to ride, more forgiving, and offer the reliability of a machine that’s not on the ragged edge. Oh yeah, and it can’t cost a million bucks, either. Well, you’re in luck, because Honda’s CRF250X offers the best of both worlds, with none of the drawbacks.

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.


  • 18-INCH REAR WHEEL: 18-inch rear wheel features same lightweight rear hub and HRC works-type lightweight-aluminum spoke nipples as used on CRF250R.
  • LED TAIL LIGHT: LED tail light integrated into rear fender. It’s light, compact and rigid.
  • WORK-STYLE REAR BRAKE: HRC works-type rear brake system with a 240mm brake rotor to its integrated rear master-cylinder and fluid reservoir, a set-up that eliminates the separate reservoir and hose.
  • REMOVABLE SUBFRAME: Removable rear subframe allows easier access to the engine and shock and simplifies maintenance.
  • SUPERIOR ERGONOMICS: Placing the rider’s legs at the narrowest part of the frame helps improve comfort and handling.
  • TWIN-SUMP LUBRICATION: Twin-sump lubrication system separates the oil supply for the crankshaft, and the piston and valve train from the clutch and transmission. This ensures a cool supply of oil to the clutch, eliminates clutch and transmission material contamination of the engine oil, reduces the amount of circulating oil and permits the use of a smaller oil pump.
  • GEAR-DRIVEN COUNTERBALANCER: The Gear-Driven Counterbalancer reduces vibration and drives the water pump. Eight clutch plates provide the surface area necessary to handle the engine's massive torque, while carefully matched clutch springs provide a light feel at the lever.
  • COMPACT, LIGHTWEIGHT 249cc UNICAM® ENGINE: Honda’s Unicam design features a single overhead camshaft and four-valve head for a powerful yet compact powerplant. Since the single camshaft sits low and takes up less space, overall engine height is more compact. It also permits a narrow included valve angle for excellent flame propagation in the combustion chamber even at higher compression ratios.
  • DUAL RADIATORS: Dual radiators feature a refined core area for improved heat dissipation compared with conventional dual-radiator designs.
  • ELECTRIC STARTERS: Electric start system ensures trouble-free starting in all conditions. It also drives the clutch side of the crankshaft to provide superior lubrication to starter gears while producing a narrow engine with a short, strong crank.
  • RENTHAL HANDLEBAR: Aluminum Renthal handlebar (971 bend) is rubber-mounted to help reduce rider fatigue and improve comfort.
  • WORKS-STYLE FRONT BRAKE: Compact twin-piston front brake caliper, anodized-aluminum brake pistons and lightweight 240mm front disc offers great stopping power while minimizing unsprung weight for improved turning and handling.
