Lighter, more compact with increased power across the entire rev range, the all-new 450cc engine maintains the previous YZ450FX model's exceptional pulling power and renowned ease-of-use, with ECU settings tailored to enhance low-end tractability and a 500 rpm higher rev limit for even more top-end power.
A redesigned aluminum bilateral beam frame with YZ450FX-specific front engine mounts provides just the right amount of strength and flex for the perfect balance of straight-line stability and cornering performance. The result is a better handling machine with lighter feel, more agility and increased traction, allowing the rider to tackle tight, technical trail sections with greater confidence.
Based on the benchmark-setting YZ450F motocrosser, the all-new YZ450FX is designed to dominate cross country competition. Lighter, more compact, with improved rider ergonomics, revised chassis, more powerful engine and next-generation Yamaha Power Tuner app all carry over directly from the 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 maneuverability in challenging off-road conditions.
