Closely based on the high-flying big-bore CRF450R, the enduro-focused CRF450X has been claiming victories in such off-road arenas as the 2008 Australian Safari and world-renowned Baja 500 and Baja 1000 races multiple times.

UNIQUE FEATURES

• T-ring-sealed chain is approximately 1.6mm narrower, and stronger compared with conventional chains
• Electric-start system for easy starting in all conditions
• Resettable, easy-to-read three-digit odometer
• Powerful 35-watt halogen headlight offers a wide range of illumination
• LED taillight integrated into rear fender
• Convenient sidestand integrated into left footpeg bracket can be easily removed for competition events
• Wide-ratio five-speed transmission
• Suspension and chassis tuned for competitive off-road riding needs
• 18-inch rear wheel for greater flat-tire protection
• Skidplate and engine guards feature a unique three-piece design

ENGINE/DRIVETRAIN

• Powerful four-stroke 449cc liquid-cooled four-valve Unicam® engine is designed to produce power across a wide rpm band for off-road riding (see Technology Section)
• 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
• Clutch cover and cylinder-head cover are made of magnesium to reduce engine weight
• Durable and versatile five-speed wide-ratio transmission
• 40mm Keihin FCR-type carburetor features four rollers on the flat slide, resulting in light throttle effort, smooth operation, crisp throttle response and excellent rideability

CHASSIS/SUSPENSION

• 18-inch rear wheel features same lightweight rear hub and HRC works-type lightweight-aluminum spoke nipples as used on CRF450R
• Front wheel features large-diameter front axle and wide wheel-bearing span for excellent rigidity
• Large 50mm-diameter rear shock damper piston for consistent performance under demanding riding conditions
• Compact twin-piston front-brake caliper, anodized-aluminum brake pistons and lightweight front-brake disc minimize 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 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 cross-section of the frame for improved comfort and handling feel
• Rear-brake pedal and shift lever are made of lightweight aluminum and are designed to complement the riding position. Brake pedal features optimized 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
• Removable rear subframe allows for easy maintenance
• Comfortable, durable controls and high-quality fasteners
• Stainless-steel clutch cable for long life
• Honda Racing-inspired colors and graphics
