Based on the benchmark-setting YZ450F motocrosser, the YZ450FX is designed to dominate cross country competition.
Its lightweight, compact chassis, powerful four-stroke engine, exceptional rider ergonomics, and Yamaha's groundbreaking next-generation Power Tuner app all carry over directly from the class-leading YZ450F.
Additional modifications tailored toward enhanced XC performance include a wide-ratio transmission, larger fuel capacity, 18-inch rear wheel, side stand, skid plate, revised ECU and suspension settings, along with a 10mm lower seat height for increased manoeuvrability in challenging off-road conditions.
