The 2011 Honda CRF450R incorporates a number of improvements that should pay dividends in the big-bore supercross and motocross racing series.
New for 2011, the Honda CRF 450 R open-class bike has revised engine tuning and new 46mm throttle body that increases low-end and mid-range power to provide improved throttle response.
The 450 four-stroke motocrosser also has a new front fork that features a lighter cartridge cylinder and all-new valving for improved control and increased ride plushness.
The CRF 450 has revised shock valving yields that improve control and increase rear wheel traction while the new Honda suspension linkage produces improved chassis balance and increased rear wheel traction in rough-track conditions.
A new Honda Progressive Steering Damper (HPSD) produces even better tracking traits than before, and a new muffler meets the 94-decibel sound level required by some racing organizations in 2011.
