YAMAHA WR450F (2007-2008) Specs, Performance & Photos

In 2008, Yamaha released the WR450F, a motorcycle part of the WR series in Yamaha's range that comprised motorcycles with different engine displacements. The 2008 machine was part of the fourth generation, including models manufactured from 2007 to 2011.

The last update was in 2007, when the bike received a new aluminum frame that dropped the overall weight by a few pounds and a revised engine with a new balancer, cylinder head, camshafts, and restyled plastics.

The bike was based on the latest version of the YZ450F motocrosser, with a lightweight aluminum frame and slim bodywork designed to offer excellent rider maneuverability in off-road conditions.

The new lightweight, compact semi-double-cradle aluminum frame was fitted on the front with a 46 mm adjustable Kayaba inverted telescopic fork. The rear end was handled by a fully-adjustable Kayaba shock absorber, delivering excellent off-road performance and handling.

For stopping power, the bike's wire-spoke wheels were fitted with a dual-piston caliper, a 245 mm disc on the rear, and a four-piston caliper with a 250 mm disc on the front, delivering strong and reliable braking performance.

In the power department, the 2008 Yamaha WR450F was powered by the same 449cc liquid-cooled single-cylinder engine fed by a Keihin carburetor, delivering an output power of 58 hp at 9,000 rpm and 49 Nm (36 lb-ft) torque at 7,000 rpm.
