The 2011 CRF450R Features
Rear Suspension - The rear suspension gets a new linkage to help give the CRF450R better handling and tracking, and a more balanced suspension performance. The fully adjustable Pro-Link® rear suspension sports an exclusive KYB® integrated reservoir, and a large 50mm rear shock damper for improved suspension action under the toughest riding conditions.
Batteryless Fuel Injection - The CRF450R was our first MX bike with fuel injection, and it's always been the standard in the class. For 2011 we've made it even better, by giving it a new throttle body and new ECU programming for crisper throttle control and even easier starting.
Lightweight Aluminum Frame - The CRF450R's race-inspired twin-spar aluminum frame revolutionized MX chassis tech when it first appeared in 1997 on the radical CR250R and has continued to do so every year since. Our latest frame boasts optimized torsional and lateral rigidity with minimized weight and maximum durability, ensuring razor-sharp handling performance. The updated subframe for 2011 takes the concept even further.
449cc Unicam® Engine
Works-Style Brakes - Honda's MX bikes have always had great brakes on the track, and the 2011 CRF450R continues that tradition. Discs front and rear with factory-spec master cylinders help haul you down fast, so you can outbrake the other guy into the turns.
Front Suspension - Kayaba front suspension features a sophisticated inverted Air-Oil Separated (AOS) system with an exclusive Honda 48mm-diameter fork, adjustability for rebound and compression damping, and 12.2" of travel. New-for-2011 settings match it up to the new rear suspension.
Honda Progressive Steering Damper - We've taken the revolutionary HPSD and made it even better for 2011 by giving it a bigger 24mm piston. You get more damping when you need it, but the HPSD operation is still completely transparent when you don't.
94 dB Exhaust System - The CRF450R's new silencer teams with the bike's revised fuel-injection throttle body and injector to help fatten up the low- and midrange.
