Motorcycles

Since its introduction, the CRF450R has served as the standard by which all other bikes are judged in the big-bore class of motocross machines. In 2012, Honda raises the bar once again with a host of improvements that will help the CRF450R stay at the head of the pack

ENGINE/DRIVETRAIN

• Lightweight, compact and powerful Unicam engine
• Advanced liquid-cooled 4-stroke 4-valve SOHC engine producing power across a broad rpm-band for smooth, easy operation
• Battery-less fuel injection tuned for strong performance and reduced noise levels
• High fuel efficiency allows use of compact and lightweight fuel tank
• Exhaust and muffler design achieves low weight, optimal pipe length for the engine and contributes to mass centralisation

CHASSIS/SUSPENSION

• New Pro-Link linkage for enhanced traction and improved suspension control
• New optimised suspension settings front and rear for even greater stability on rough terrain
• New more rigid fork outer tubes for improved suspension action and more accurate steering
• New stiffer fork springs for a higher spring impact rate, giving enhanced chassis balance and stability when approaching and landing from jumps
• Next generation twin-spar aluminium frame is lightweight and provides optimal rigidity for better handling

ADDITIONAL FEATURES

• New footpeg design with wider footpegs and a lighter footpeg bolt for enhanced rider stability
• Tough and lightweight Honda Progressive Steering Damper for precise steering
• Striking Honda Racing-inspired graphics
• New chain roller for added durability
• Unique lightweight and compact Honda Progressive Steering Damper (HPSD), developed by Team Honda, improves cornering ability and reduces rider fatigue. More aggressive steering characteristics are augmented while straight-line stability is assisted. The damper’s progressive damping action smoothly increases with handlebar deflection, while producing very natural steering characteristics and feel
• Brake pedal and shift lever are made of lightweight aluminium and designed to complement the riding position. Brake pedal features optimised ratio to match integrated rear-brake master cylinder design
• Slim, aggressively styled plastics allow easy rider movement and feature Honda Racing-inspired colours and graphics
