2010 Yamaha WR Review


The 2010 Yamaha WR range of motorcycles are versatile. Direct descendants of the Yamaha YZ bikes, the WR series have evolved to perform on both paved and unpaved terrains with ease, making Yamaha’s off-road prowess street accessible. The WR range includes the WR250X, WR250R, and WR450F.

While the WR250X bike is not exactly an Enduro, a Supermoto, or a sport bike, the weight and handling of this Supermoto-inspired bike demonstrates power and leans more towards riders who prefer to spend more time on asphalt than woody terrain. The WR250R, on the other hand, is more suited for riders who prefer to spend more time in the dirt. The 2010 Yamaha WR450F is mostly an off-road motorcycle.
