Honda CRF450R

For 2008, the CRF450R's light and rigid aluminium frame and responsive Works racer suspension systems are now complemented by a new Honda Progressive Steering Damper (HPSD). The HSPD is complimented by a number of other major upgrades that make Honda's top motocrosser more rideable than ever before. With a stroke of fresh engineering insight, Honda have designed the HPSD specifically to augment more aggressive turning characteristics rather than only assisting straight line handling, as has been the case with past applications. This means a higher level of front end traction with significantly enhanced steering feel, specifically a more "planted" feel in turns for better front wheel control, especially under dry, hard-packed track conditions. The net result is greater cornering speed, a higher level of front-end confidence and reduced rider fatigue thanks to this damper's astounding new turning ease. Additionally, HPSD enhances handling in whoops and fast track sections, all of which means faster lap times over the course of a race.

The steering head has also been completely redesigned and re-tuned for correct flex/stiffness properties, and an HPSD mounting lug is incorporated. Likewise, the triple clamps were newly designed to yield the correct degree of stiffness, given the new forces imparted by the steering damper system. Every force input was carefully calculated and matched so that the chassis, suspension and HPSD all worked in concert as one system.

Powered by a strong Unicam 4-stroke engine, the '08 450R also features a multitude of upgraded features including:
_ Tapered exhaust head pipe improves low-end and mid-range power
_ Lighter weight counter balancer shaft and drive gears
_ New Works type multi map CDI system uses transmission gear-position sensor to provide specific ignition maps
_ Friction reducing coating on the clutch basket, clutch centre and
pressure plate
_ Front fork triple clamps feature 22mm offset for improved cornering
_ Showa fork features a larger cartridge rod and new cartridge oil piston, plus stiffer springs for improved mid-stroke action
_ Rear damper valving matches changes to front fork
_ Works style front and rear brake rotors to reduce unsprung weight
_ Rev limit increased to 11,270rpm.

The CRF450R's liquid cooled 449cc engine pumps out nearly 90kW per litre while maintaining Honda's legendary simplicity and dependability. Lightweight titanium intake valves allow for smaller valve springs, whilst the forged slipper piston is 130g lighter. A 41mm FCR-type carburettor features four rollers on the flat slide, resulting in light throttle effort, smooth operation and crisp throttle response. An eight plate clutch provides ample surface area to handle the engine's massive torque, while carefully matched clutch springs provide a light feel at the lever.

With a frame design that allows side covers to have larger air intake ducts, air flow is significantly increased in the mid & upper rpm ranges. Rider ergonomics are also optimised by adapting the handle- bar, seat and footpeg height to place the rider's legs at the narrowest cross-section of the frame for improved comfort and handling feel. This and much more make the 2008 CRF450R a must have for the fair dinkum MX fan. See your Honda dealer for pricing.
