New Honda CRF450X Trail / Enduro Bike

The dynamic, electric start CRF450X takes off-road riding to an exhilarating climax, winning hearts and minds while dominating such world-renowned off-road endurance races as the Baja 1000.  Based on Honda's phenomenal CRF450R big-bore, 4-stroke, motocross racer, the CRF450X is breathtakingly powerful.  A slim, easy-to-ride form and rugged, long travel suspension systems are augmented by a Honda's Progressive Steering Damper, which eases control and smoothes handling in cornering and over rugged terrain.

Features and Benefits

Engine / Drivetrain

Innovative Honda Unicam valve train provides both the lightweight of a compact single-cam design and an optimum combustion chamber shape for maximum power at all engine rpm.
Unicam valve train features a single carburized camshaft directly actuating two 35mm titanium intake valves. The camshaft’s centre exhaust lobe actuates two 30mm 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, and produce a narrow engine with a short, strong crankshaft.
Lightweight titanium intake valves permit use of smaller valve springs, reducing overall engine height.
Magnesium ACG cover, clutch cover and cylinder head cover reduce engine weight.
Lightweight NiCaSil cylinder lining ensures cooler and quieter operation for extended engine life.
40mm 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 a 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. Coolant recovery tank is located underneath engine for improved mass centralisation. Coolant tank is protected by a plastic skid-plate.
Gear-driven balancer reduces vibration and drives the water pump.
Eight-plate clutch provides 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 stronger compared to conventional chains.
Durable and versatile 5-speed wide-ratio transmission.

Chassis / Suspension

• Advanced fourth-generation twin-spar aluminium frame.
• Lightweight and compact Honda Progressive Steering Damper (HPSD) developed by Team Honda for improved cornering ability and reduced rider fatigue.
• HPSD features a compact damper attached to the lower triple-clamp and the steering head to augment more aggressive steering characteristics and assist straight-line handling. Tuned specifically for higher speed, non-motocross, off-road riding applications, the CRF450X damper incorporates different valving and settings compared to units mounted on motocross models. HPSD provides confident straight-line control at high speeds, a planted feel in corners, less rider fatigue and outstanding handling over a wider variety of terrain and riding conditions.
• 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.
• Suspension and chassis tuned for competitive off-road riding needs.
• Lightweight 47mm Showa inverted twin-chamber cartridge-type fork with aluminium dampers is derived from the CRF450R and features settings unique to the CRF450X.The fork offers 315mm of stroke, 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.
• 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 lightweight.
• Front wheel features large-diameter front axle and wide wheel-bearing span for excellent rigidity.
• 18" rear wheel features same lightweight rear hub and HRC Works-type lightweight aluminium spoke nipples as used on CRF450R 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, anodized 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.
