- Powerful liquid-cooled, electric-start 249cm³ 4-stroke 4-valve Unicam engine is designed to produce strong power across a wide rev range for easy-to-control operation.
- Push-button electric starter ensures easy start-ups in all conditions.
- Innovative Honda Unicam valve train provides both the light weight of a compact single-cam design and an optimum combustion chamber shape for maximum power at all engine speeds.
- Unicam valve train features a single carburised camshaft directly actuating two 31mm titanium intake valves. The camshaft’s centre exhaust lobe actuates two 26mm steel exhaust valves via a forked, low-friction, roller rocker-arm.
- Electric starter drives the clutch side of the crankshaft to provide superior lubrication of starter gears, while making possible a narrow engine with a short, strong crankshaft.
- Magnesium ACG cover, clutch cover and cylinder head cover reduce engine weight.
- Forged 12.9 : 1 compression slipper piston is lighter than conventional designs, for quick-revving response while maintaining excellent cylinder sealing and high-rpm power.
- 37mm Keihin FCR-type carburettor features four rollers on the flat slide for light throttle effort, smooth operation, crisp throttle response and excellent rideability.
- Carburettor features throttle position sensor (TPS) that helps maintain linear throttle response throughout the rpm range.
- Twin-sump lubrication system separates oil supply to crankshaft, piston and valve train from supply to clutch and transmission. This ensures a steady supply of cool 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.
- Exhaust system uses a lightweight stainless steel exhaust header and an aluminium silencer equipped with a spark arrester which complies with all local fire and noise regulations.
- Dual radiators feature a refined core area for improved heat dissipation compared to conventional dual-radiator designs, and a compact coolant recovery tank.
- Gear-driven balancer reduces vibration and drives the water pump.
- Eight-plate clutch provides surface area necessary to handle engine’s strong torque, while carefully matched clutch springs provide a light feel at the lever.
- T-ring-sealed chain is approximately 1.6mm narrower and stronger than conventional chains.
- Durable, smooth-shifting wide-ratio 5-speed transmission.

 

- Fourth-generation twin-spar aluminium frame derived from Honda’s CR series of championship motocrossers.
- Semi-double-cradle frame design features a single, large-diameter tapered down-tube for optimised frame rigidity, with two rugged box-section rails attached to its base to support the engine. A forged aluminium steering head provides a compact and extremely durable mount for the frame spars and engine down-tube.
- Narrow frame spars and tall swingarm pivot plates combine to create a narrow overall frame cross-section for superb rider comfort and manoeuvrability.
- Suspension tuned for competitive off-road riding needs.
- Lightweight, 47mm Showa inverted twin-chamber cartridge-type fork with aluminium dampers is derived from the CRF250R and features settings unique to the CRF250X. The fork offers 280mm of travel, 16-step rebound and 16-step compression damping adjustability, as well as stiffer springs for improved mid-stroke action. The inner surfaces of the front fork outer tubes receive the same honing treatment as Works bikes for low-friction operation.
- Pro-Link rear suspension system features single, fully adjustable Showa rear damper with optimised damper settings and 312mm of wheel travel, separate low-speed (13-step) and high-speed (3.5 turns) compression damping adjusters, and 17-step adjustable rebound damping.
- Large 50mm rear damper piston diameter provides consistent performance under demanding riding conditions.
- Swingarm features a dual-axis, double-taper design with a large cast aluminium cross-member offering high strength and light weight.
- Front wheel features large-diameter front axle and wide wheel-bearing span for excellent rigidity.
- 18" rear wheel features same lightweight rear hub and lightweight HRC Works-type aluminium spoke nipples as used on CRF250R for reduced unsprung weight and enhanced protection against flat tyres.
- Large, 25mm-diameter rear axle and large-diameter bearings provide optimum rigidity and strength to withstand torturous track conditions.
- Compact dual-piston front brake calliper, anodised aluminium brake pistons and lightweight 240mm Works-style brake rotors minimise unsprung weight for improved turning and handling.
- HRC Works-type rear brake system integrates the rear master cylinder and fluid reservoir into one compact, lightweight unit.
- Dunlop 742FA front tyre improves turning feel and traction.
