Yamaha WR450F 2015

Yamaha WR450F 2015

The new WR 450F is a genuine racing enduro that is technically and innovatively at the forefront. A Kayaba chassis that is unparalleled in series production, top brakes. A slightly larger tag would be fine and a little more "carburettor feeling" in the rev range. But the best thing is the possibilities offered by the uncomplicated Powertuner.

The engine of the YZ450F is powerful and somewhat aggressive, but can be optimised via mappings. What is very noticeable about the YZ450F is the strong intake noise from the engine, but you quickly get used to it. The handling is also very good and the gears are easy to shift. Unlike the 250, the YZ450F GYTR is a little lighter and nicer to ride than the standard 450. The chassis responds well, works very well and is very easy to handle. This makes it suitable for the hobby rider.
