HONDA CRF250X ENGINE/DRIVETRAIN · Powerful four-stroke 249cc liquid-cooled four-valve Unicam® engine is designed to produce power across a wide rpm band for easy-to-control operation · Electric starter drives the clutch side of the crankshaft to provide superior lubrication to starter gears, and produce a narrow engine with a short, strong crankshaft · Compact, lightweight engine assembly weighs only 27kg · ACG cover, clutch cover and cylinder-head cover are made of magnesium to reduce engine weight · Forged 12.9:1 compression slipper piston is lighter than a conventional design, revving quickly while maintaining excellent cylinder sealing and high-rpm power · 37mm Keihin FCR-type carburettor features four rollers on the flat slide, resulting in light throttle effort, smooth operation, crisp throttle response and excellent rideability · Carburettor features a throttle position sensor (TPS) to help maintain linear throttle response throughout the rpm range · Twin-sump lubrication system separates the oil supply for the crankshaft, 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 · Exhaust system uses a lightweight stainless steel exhaust header and muffler equipped with spark arrester · Dual radiators feature a refined core area for improved heat dissipation compared to conventional dual-radiator design, and coolant recovery tank · Gear-driven balancer 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 · T-ring–sealed chain is approximately 1.6mm narrower and is stronger compared to conventional chains · Durable five-speed wide-ratio transmission CHASSIS/SUSPENSION · Fourth-generation Twin-Spar Aluminium Frame with forged-aluminium steering head · 18-inch rear wheel features same lightweight rear hub and HRC works-type lightweight aluminium spoke nipples as used on the CRF250R · Front wheel features large-diameter front axle and wide wheel-bearing span for excellent rigidity · Rear-axle diameter of 25mm and large-diameter bearings provide optimum rigidity to withstand torturous off-road conditions · Revised, sophisticated Inverted Twin-Chamber Cartridge Fork · Pro-Link® Rear Suspension with new damper settings · Large 50mm rear shock damper piston diameter for consistent performance under demanding riding conditions · HRC works-type rear brake system integrates the rear master cylinder and fluid reservoir, eliminating the need for a separate reservoir and hose assembly ADDITIONAL FEATURES · Rider ergonomics are optimized by adapting the handlebar, seat and footpeg height to place the rider’s legs at the narrowest frame width for improved comfort and handling feel · 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 help 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 · Adjustable front brake lever · Quick-adjust clutch · Chain guide material offers improved wear resistance, and service life is five times greater than conventional materials · Front disc brake cover helps protect rotor and calliper from damage · Removable rear subframe allows easy maintenance · Washable, two-stage foam air filter for optimal engine protection and easy maintenance · Comfortable, durable controls and high-quality fasteners · Stainless steel clutch cable for long life · Honda Racing™-inspired colours and graphics. |
