YAMAHA WR450F (2010-2011) Specs, Performance & Photos

In 2011, the Japanese motorcycle manufacturer launched the Yamaha WR450F, an off-road lightweight machine part of the WR series in Yamaha's range that comprised models with different engine displacements.

The Yamaha WR450F started its life in 1998 with the WR400F model that packed a 400cc engine and shared many components and design features with the Yamaha YZ400F motocross model.

The bike was manufactured over several generations, while the 2011 model was the last model manufactured for the fourth generation. Over its production years, the motorcycle featured several technical and performance modifications.

The 2011 Yamaha WR450F was built on a lightweight aluminum frame with a lightweight aluminum swingarm, a slim bodywork profile, and the performance of the YZ450F machine. The bike delivered excellent maneuverability, making it a great choice for riders of all skill levels.

In the engine department, the specifications were retained from previous models, with a 449cc four-stroke liquid-cooled single-cylinder engine boasting 58 hp on tap at 9,000 rpm and 49 Nm (36 lb-ft) torque at 7,000 rpm.

All the power generated by the engine was directed to a five-speed constant mesh manual transmission that spun the rear wheel through an O-ring sealed final chain drive.

The braking power was also retained from previous models, including a four-piston caliper with a 250 mm disc mounted on the front wheel and a dual-piston caliper with a 245 mm disc mounted on the rear wheel.
