2011 Honda CRF450R overview

The 2011 Honda CRF450R is a four-stroke motocross racing bike with a liquid-cooled, fuel-injected 450cc single-cylinder engine, SOHC valve train, and five-speed transmission. Its aluminum perimeter frame pairs with adjustable KYB suspension, and Honda Progressive Steering Damper (HPSD) equipment is standard. Updates for 2011 include revised engine tuning with a new 46mm throttle body, a lighter fork cartridge with new valving, revised shock valving, a new suspension linkage, a larger HPSD piston increased from 20mm to 24mm, and a redesigned muffler rated at 94 dB. The suspension offers 12.2 in of front travel and 12.6 in at the rear.

Who it's for

This CRF450R is for motocross racers and riders focused on racing, with track use in mind rather than street riding. Its 450cc four-stroke engine, five-speed transmission, and adjustable front and rear suspension suit riders setting up a bike for motocross conditions. It is not street legal in the US, so it does not fit a buyer looking for a road-registered motorcycle.
