2011 Honda CRF450R - Riding Impression

So, among the tweaks and changes to the 2011 CRF450R, Honda has redesigned the muffler to meet the strict new 94 dB sound regulations required by many racing organizations. But this doesn’t mean that engineers sacrificed power or performance to achieve this standard. There wasn’t a lot to complain about on last year’s 450R, but when comparing that model to the ultra-torquey Yamaha YZ450F, it became apparent that the Honda could use a bit more bottom-end and midrange grunt. For 2011, the throttle-body diameter has been reduced from 50mm to 46mm, while ignition and fuel mapping have been optimized to achieve a better hit of power in those areas.Our first ride on the new model took place at Jeremy McGrath’s private ranch in the mountains east of San Diego. McG’s track is much more old-school motocross than King-of-Supercross jumpy; soft and silty terrain and 4900 feet of elevation provided a good test of the Open-class Honda’s engine performance.

“The combination of exhaust and throttle-body changes creates a better connection between throttle-grip movement and actual engine output,” said Off-Road Editor Ryan Dudek. “Power is more evenly distributed throughout the rev range with fewer spikes in the delivery and a more predictable response.”

Changes to the chassis include revised fork and shock damping settings, in addition to a new swingarm link. The goal was to increase traction while providing a plusher ride, both of which were achieved. The Honda Progressive Steering Damper (HPSD) also has been redesigned, with the diameter of the piston rod increased from 20 to 24mm.

“Dial in a few clicks of damping and the difference is much more noticeable when compared to the previous unit,” said Dudek. “Just three clicks on the new damper provided a very noticeable change, which slowed steering in tight turns but improved stability through rough, fast, straight sections of track.”

Individually, the changes to the $8199 (up $100) 2011 CRF450R don't seem too far removed from last year's model; but collectively, they add up to a better bike, one that in its previous forms was already an eight-time winner of Cycle World's Best Motocrosser award. Need we say more?
