Key Features

  • All plastic body components designed for slim, aggressive styling and light weight
  • Ample 7.6-litre fuel tank capacity
  • Resettable, easy-to-read three-digit competition odometer
  • Rider ergonomics optimised by positioning rider’s legs at frame’s narrowest width for improved comfort and handling feel
  • Rear brake pedal and shift lever made of lightweight aluminium and designed to complement the riding position
  • Wide, cleated stainless steel footpegs are self-cleaning, resist corrosion, provide excellent grip and fold for extra ground clearance
  • Aluminium Renthal handlebar (971 bend) is rubber-mounted to reduce rider fatigue and improve comfort
  • Handlebar holders provide two different mounting positions to match rider preference
  • Works-type handlebar grips add to rider comfort
  • Chain guide material offers improved wear resistance, with five times longer service life than conventional materials
  • Removable rear sub-frame allows easy maintenance
  • Washable, easy-access two-stage urethane foam air filter for optimal engine protection and easy maintenance
  • Stainless steel clutch cable for long life

Engine

  • 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

Chassis

  • 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

Colours

  • Extreme Red (with white number plate and sidecovers)
