YAMAHA WR450F: CHANGES OVERVIEW
The design of the WR was eventually created with the active participation of many riders, especially former MXGP party Josh Coppins. The new machine mainly relies on the engine, chassis, suspension, gearbox and brake system, the World Cup champion YZ450F, which directly impacts on reducing the weight of the motorcycle, improving capacity their own and improve stability.
After the first WR model line revolution, which appeared under the name 1998 WR400F, there are five main series of updates. In 2001 he began to be issued WR426F, and Yamaha WR450F – 2003.

The difference between the WR and the YZ frame is designed to adapt later to move on rough terrain and increase the level of feedback for the driver. Also the 2mm front engine suspension size has been reduced.
The Yamaha WR450F has a new four-bar navigation system, which perfectly complements an updated SUV package, as it allows the driver to customize the landing without the expense of additional hardware.

The variable injection angle, the improved feature of the throttle opening, has been moved the muffler starter to be much shorter and quieter. Can both electronic and kick-start.
The generator provides an electric starter, lights and electric fuel injection system with a voltage of 14 V and a capacity of 160 watts.

The Yamaha WR450F demonstrates an upgraded compression ratio equivalent to 12.5:1, which is extremely smooth changing throughout the power curve. Drivers who like motorcycles, instantly release a great amount of torque, amazed by the instantaneous transfer of power in the WRF. Usually first slow acceleration is expected, and then a quick jump on the upper end, but this car is going almost as much as her YZ450F prototype. You can go for a second from second to third gear in almost every part of the complex vegetation or serpentine slopes.
Members note that the clutch when driving in high gear, thanks to the smooth delivery of power for almost unnecessary control.
