  • Smooth-shifting wide-ratio 5-speed transmission.
  • Suspension tuned for enduro riding needs.
  • 18" rear wheel provides enhanced protection against flat tyres.
  • New T-ring sealed chain is narrower, stronger and lighter compared to conventional chains.
  • Engine/Drivetrain;

  • Powerful liquid-cooled 449cm3 4-stroke 4-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 of starter gears, and produce a narrow engine with a short, strong crankshaft.
  • Lightweight, compact, internal auto decompressor system provides superb coldstarting and hot-starting operation.
  • Compact, lightweight engine assembly weighs only 32.2kg.
  • Unique 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 rpm.
  • Unicam valve train features a single carburised camshaft directly actuating two 35mm titanium intake valves from above. The camshaft's centre exhaust lobe actuates two 30mm steel exhaust valves via a forked, low-friction, roller rocker-arm.
  • Lightweight titanium intake valves permit use of smaller valve springs, reducing overall engine height.
  • High-strength, low-carbon steel crankshaft with carburised main journals for maximum durability at sustained high-rpm operation.
  • ACG cover, clutch cover and cylinder head cover are made of magnesium to reduce engine weight.
  • Forged 12.5:1 compression slipper piston is lighter than conventional designs, for quick-revving response while maintaining excellent cylinder sealing and high-rpm power.
  • Double-carburised connecting rod utilises an updated big-end needle bearing and thrust washers for maximum high-rpm performance and durability.
  • Lightweight NiCaSil cylinder lining ensures cooler and quieter operation for extended engine life.
  • Press-fitted aluminium spark plug pipe fits between forked exhaust rocker arms, further contributing to compact cylinder head design.
  • 40mm Keihin FCR-type carburettor features four rollers on the 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 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.
  • Vertically split crankcases feature a built-in oil pump, reducing weight compared to conventional designs.
  • 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 designs. Coolant recovery tank is located underneath engine for improved mass centralisation. Coolant tank is protected by a plastic shield.
  • 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.
  • New T-ring-sealed chain is approximately 1.6mm narrower, and stronger compared to conventional chains.
  • Durable 5-speed wide-ratio transmission.
  • Chassis/Suspension;

  • All-new 4th-generation twin-spar aluminium frame is derived from Honda's CR series of championship motocrossers.
  • Forged aluminium steering head and tapered down-tube section designed for optimised frame rigidity. In addition, tall swingarm pivot plates and narrow frame spars create a narrow overall frame cross-section for superb rider comfort and manoeuvrability.
  • Semi-double-cradle frame design features a single, large-diameter tapered downtube. Two rugged box-section rails attach to the base of the downtube and support the engine. A forged aluminium steering head provides a compact and extremely durable mount for the frame spars and engine downtube.
  • The aluminium frame design is matched to rider ergonomics to maximise handling and control operation.
  • 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 travel, 16-step rebound and 16-step compression damping adjustability. 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 a single, fully adjustable Showa rear damper and 315mm 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 HRC Works-type lightweight aluminium spoke nipples as used on CRF450R for reduced unsprung weight.
  • Rear axle diameter of 25mm and large-diameter bearings provide optimum rigidity and strength to withstand torturous track conditions.
  • Large, 240mm front and rear brake rotors.
  • Compact dual-piston front brake calliper, anodised aluminium brake pistons and lightweight front brake rotor minimise unsprung weight for improved turning and handling.
  • HRC Works-type rear brake system integrates the rear master cylinder and fluid reservoir, eliminating the need for a remote master cylinder reservoir and hose assembly.
  • Additional Features;

  • All plastic body components (radiator shroud, side covers, rear fender, seat base, fuel tank, front fender, and front headlight) are designed for slimmer, more aggressive styling and light weight.
  • Airbox features easy access to reusable foam air filter.
  • Rider ergonomics are optimised by adapting the handlebar, seat and footpeg height to place the rider's legs at the narrowest cross-section of the frame for improved comfort and handling feel.
  • Seat cushion uses foam construction that follows the shape of the fuel tank, providing a smooth transition to increase rider mobility and comfort.
  • Non-slip seat cover enhances rider control.
  • Rear brake pedal and shift lever made of 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 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.
  • CR handlebar holders provide three different mounting positions: standard CRF450X holder (CRF450R/CR125R/CRF250X-type) provides +/-3mm fore or aft position to match rider preference, and optional holder (CR250R-type) provides neutral position.
  • Works-type handlebar grips add to rider comfort.
  • Adjustable front brake lever.
  • Quick-adjust clutch perch.
  • Chain guide material offers improved wear resistance, with service life five times greater than conventional materials.
  • Front disc brake cover helps protect rotor and calliper from damage.
  • Removable rear sub-frame allows easy maintenance.
  • Washable, two-stage foam air filter for optimal engine protection and easy maintenance.
  • Comfortable, durable controls and high-quality fasteners.
