HONDA CRF450R (2004-2005) Specs, Performance & Photos

The Honda CRF450R was a racing motocross motorcycle powered by a 450cc four-stroke engine. It debuted in 2002 to replace the Honda CR250R and has been manufactured for over six generations.

The bike was introduced in 2002, and unlike its Yamaha YZ426 competitor, the CRF450R was made around an aluminum frame. In 2003, the bike received a longer shock absorber and a new linkage for a raised rear end and steepened head angle. Also, the camshaft, exhaust, and ignition map were revised, while in 2004, the handlebar was changed in size.

In 2002, the Japanese motorcycle maker launched the Honda CRF450R, a motocross motorcycle with standard features, such as a high-mounted front fender, a single seat, a single exhaust system with a high-mounted silencer, and wire-spoke wheels with off-road tires.

The bike's aluminum frame housed the suspension system, which comprised a 47 mm inverted cartridge-type fork with 315 mm wheel travel on the front and a Pro-Link swingarm with a Showa adjustable shock on the rear, offering 320 mm wheel travel.

Two 240 mm discs, one front and one rear, achieved the braking performance. The front one was clamped by a two-piston caliper, and the rear by a hydraulic caliper.

The 2002 Honda CRF450R had installed a 449cc four-stroke liquid-cooled single-cylinder engine managed by a 40 mm flat-side Keihin carburetor. A five-speed manual transmission assisted the engine, sending the power to the rear end via a final chain drive.
