YAMAHAWR450F 2009 - 2010

　　The Yamaha WR450F was a small off-road motorcycle manufactured by Yamaha over several generations. The bike was part of the WR series in Yamaha's range, comprised of motorcycles with different engine displacements.

　　In 2010, Yamaha launched the WR450F, an off-road machine in its fourth generation, which packed a lightweight aluminum frame and swingarm, a slim bodywork designed for excellent maneuverability, and the performance of the Yamaha YZ450F machine.

　　The bike came equipped with standard features right from the factory, such as a high-mounted front fender and exhaust system, a small headlight integrated into a small cowl, a single seat, an aluminum frame and swingarm, and lightweight aluminum wheels.

　　As for the power figures, the 2010 Yamaha WR450F took its muscles from a 449cc four-stroke liquid-cooled single-cylinder engine, delivering a power output of 58 hp with a peak forge at 9,000 rpm and 49 Nm (36 lb-ft) torque at 7,000 rpm.

　　The bike's power was handled by a five-speed constant mesh manual transmission spinning the rear wheel through an O-ring sealed final chain drive.

　　For stopping power, the wire-spoke wheels were fitted with a four-piston caliper, a 250 mm disc on the front, and a 245 mm disc with a dual-piston caliper on the rear, offering excellent braking performance.

　　In the suspension department, the 2010 Yamaha WR450F was equipped with a fully-adjustable Kayaba shock absorber on the rear and a 46 mm adjustable inverted Kayaba telescopic fork on the front.
