Based on the benchmark-setting YZ450F motocrosser, the WR450F is made to be versatile. Lighter, more compact, and with a lower centre of gravity, the WR450F packs enhanced performance in the bush at all speeds. With a more tractable and longer pulling engine, revised ECU settings, improved chassis, lightweight brake system and more, the WR450F offers increased performance and handling in the toughest off-road conditions.
