The 2019 Honda CRF450RWE is a motocross race bike with a 450 cc, fuel-injected, liquid-cooled four-stroke single, SOHC four-valve engine and five-speed transmission. Its 2019 Works Edition package brings a cylinder head with hand-polished ports, a Yoshimura titanium slip-on muffler and ECU settings for more low- and mid-range torque. It also adds Ken Roczen’s No. 94 graphics with a Throttle Jockey seat cover, black D.I.D LT-X rims and triple clamps, a gold RK chain, and titanium-nitride-coated fork legs and shock shaft.

The CRF450RWE has electric start, launch control, a handlebar map switch and a stock skid plate. Its fully adjustable Showa suspension provides 12.0 in of front travel and 12.4 in at the rear. Seat height is 37.8 in, curb weight is 247 lb, and fuel capacity is 1.66 gal.

Who it's for

This bike is for experienced motocross racers and riders focused on closed-course competition. Its 450 cc engine, 247 lb curb weight and 37.8 in seat height suit riders prepared to manage a powerful race bike and a tall riding position. The Works Edition’s race-focused engine, exhaust and suspension hardware make it a fit for track sessions and motocross events, not riders looking for a street-legal trail bike.
