New Honda CRF250R

The brilliant future of motocross arrives in the aggressive new, high-flying CRF250R.  Fun and high-spirited, the incomparable CRF250R combines lightweight, strong, versatile power with confident, responsive handling.  One of the finest off-road bikes to be found, it features slim ergonomics and rugged, long-travel suspension.  Newbie's beware - this is definitely one for the experienced riders.  New cylinder Head, mapping, carburetion and suspension settings make this yet another step forward.  Just watch Michael Phillips and Justin McDonald go on this years Motocross!

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. 
• Dunlop 742FA front and 756 rear tyres provide superior traction and cornering 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. 
• Honda Racing-inspired colours and graphics.

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 314mm 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.
