New Honda CRF250R Black Edition

The CRF250R provides a potent blend of quick-revving, race-bred 4-stroke performance that negotiates the motocross circuit's tight berms and big air jumps with confident ease

Features and Benefits

Additional features

• Lightweight, compact Honda Progressive Steering Damper (HPSD) developed by Team Honda for improved cornering ability and reduced rider fatigue. HPSD features a compact and rugged hydraulic damper attached between the steering head and the lower triple clamp to augment more aggressive steering characteristics and assist straight-line handling. The damper’s progressive damping action smoothly increases with handlebar deflection, which produces very natural steering characteristics and feel.
• Frame design allows larger intake ducts in airbox side covers, contributing to excellent airflow in the mid and upper rpm ranges.
• Rider ergonomics are optimised by adapting handlebar, seat and footpeg height to place the rider’s legs at the narrowest cross-section of the frame for maximum comfort and best handling feel.
• New design front disc brake cover helps protect rotor and calliper from damage.
• Removable rear sub-frame allows easy maintenance.
• Washable, two-stage foam air filter offers optimal engine protection and easy maintenance.
• Comfortable, durable controls and high-quality fasteners.
• Stainless steel clutch cable for maximum durability.
• Cleated rear brake pedal and folding shift lever constructed in lightweight aluminium and designed to complement the riding position. Brake pedal features optimised ratio to match integrated rear-brake master cylinder design.
• Wide, cleated stainless steel foot pegs are self-cleaning, corrosion-resistant, provide excellent grip and fold away for extra ground clearance.

Engine/Drivetrain

• Powerful 249cc liquid-cooled 4-stroke 4-valve Unicam engine is designed to produce optimal, easy-to control power across a wide rpm range.
• Unicam valve train provides both the lightweight of a compact single-cam drive and an optimum combustion chamber shape for maximum power at all engine speeds.
• Unicam valve train features a single carburized camshaft directly actuating two 31mm titanium intake valves. The camshaft’s centre exhaust lobe actuates two 26mm steel exhaust valves via a low-friction forked roller rocker arm.
• Lightweight and compact internal auto decompressor and handlebar-mounted hot-start system provide superb operation, hot or cold.
• Lightweight titanium intake valves permit use of smaller valve springs, reducing overall engine height.
• Lightweight counter-balancer shaft and drive gears.
• Clutch features judder spring for smoother engagement.
• ACG cover, clutch cover and cylinder-head cover made of magnesium for reduced engine weight.
• Forged slipper piston and rings are lighter than conventional designs, revving quickly while maintaining excellent cylinder sealing, high 13.0:1 compression ratio and high-rpm power.
• Lightweight NiCaSil cylinder lining ensures cooler and quieter operation for extended engine life.
• 40mm Keihin FCR carburettor features four rollers on flat slide, resulting in very light throttle effort, smooth operation, crisp throttle response and excellent rideability.
• Carburettor features a Throttle Position Sensor (TPS) that helps maintain linear throttle response throughout the rev range and smooth power response.
• Twin-sump lubrication system separates oil supply to crankshaft, piston and valve train from clutch and transmission. This ensures a steady supply of cool oil to the clutch, eliminates clutch and transmission material contamination of the engine oil, and reduces the amount of circulating oil, which permits the use of a smaller oil pump.
• Dual-muffler exhaust system centralises mass and reduces turning inertia to improve the CRF250R’s lightweight feel.
• Dual-muffler exhaust system also increases low-rpm torque.
• Exhaust system uses a lightweight stainless exhaust header and repackable aluminium silencers.
• Gear-driven balancer reduces vibration while also driving the water pump.
• Rugged eight-plate clutch provides ample surface area to handle the engine’s massive torque, while carefully matched clutch springs provide a light feel at the lever.
• Durable five-speed close-ratio transmission.

Chassis/Suspension

• Dual-axis, double-taper swingarm design integrates a large cast aluminium cross-member.
• Front and rear wheels feature lightweight HRC Works type aluminium spoke nipples for reduced unsprung weight.
• Rear axle diameter of 25mm and large-diameter bearings provide significant rigidity to withstand variable and punishing track conditions.
• Lightweight, 47mm Showa inverted twin-chamber cartridge-type fork with new separator, Kashima-coated cartridge cylinder and new settings. Fork offers 279mm of travel and 16-step rebound and compression damping adjustability.
• Pro-Link rear suspension system features single fully adjustable Showa rear damper with 315mm of wheel travel, separate low-speed (13-step) and high-speed (3.5 turns) compression damping adjusters and 17-step rebound damping.
• Large 50mm-diameter rear damper piston performs consistently under demanding riding conditions.
• Link-type front brake master cylinder and lightweight brake rotor combine to provide strong braking control.
• Compact dual-piston front brake calliper, anodized aluminium brake pistons and lightweight front brake rotor minimise unsprung weight for improved turning and manoeuvring.
• HRC Works-type rear brake system integrates the rear master cylinder and fluid reservoir, eliminating conventional external reservoir and hose.
• 240mm front and rear disc brake rotors.
• Front fork triple-clamps feature 22mm offset for superb cornering.
• Rear damper valving matches front fork settings.
