The bike that revolutionized open-class motocross has gotten even better for 2011. The prodigious powerband produced by its mighty 449 cc Unicam four-stroke liquid-cooled engine is now even stronger, thanks to more low-end pull and midrange grunt along with enhanced throttle response via a new throttle body in the battery-less PGM-FI electronic fuel injection system. A revised Kayaba fork and improvements to the rear suspension linkage and shock settings produce better control, increased ride plushness and enhanced rear-wheel traction. As well, the improved Honda Progressive Steering Damper (HPSD) neatly tucked behind the front number plate means extra stability when you need it most. Better power delivery, improved handling, even a quieter exhaust system... if you don't like settling for second best, then don't wait to give yourself the Honda CRF450R advantage.
