2009 Honda CRF450X

2009 Honda CRF450X

Introduction

Closely based on the high-flying big-bore CRF450R, the enduro-focused CRF450X has been claiming victories in the off-road arena since it first appeared on trails across the world.

Featuring awesome power and a slim, easy-to-ride form, it takes off-road riding to exhilarating peaks of fun and excitement. Its rugged, long-travel suspension systems are augmented by the Honda Progressive Steering Damper (HPSD), which eases control and smoothes handling in cornering and over rugged terrain.

Are you chasing the ultimate accolade, or searching for the incomparable thrills that come from cutting loose on an amazing new cross country trail? The mighty CRF450X is the definitive tool to give you both the adrenaline and the stamina to push your own limits time and time again, and keep you coming back for more.

Engine

  • Powerful liquid-cooled, electric-start 449cm3 4-stroke 4-valve Unicam engine is designed to produce power across a wide rpm band for easy-to-control operation
  • Push-button electric starter ensures easy start-ups in all conditions
  • Innovative 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
  • 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
  • Forged 12 : 1 compression slipper piston is lighter than conventional designs, for quick-revving response while maintaining excellent cylinder sealing and high-rpm power
  • 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
  • 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
  • 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

  • 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
  • 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
  • Pro-Link rear suspension system features single, fully adjustable Showa rear damper with optimised damper settings
  • 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
  • Compact dual-piston front brake calliper, anodised 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
