The revolutionary YZ450F will have many gazing far into the future. By slanting the cylinder rearward and reversing the intake and exhaust ports, the YZ450F's mass is more centralized for amazing balance, unprecedented handling and cornering. The Bilateral Beam frame and suspension offer fantastic feedback to the rider. Add fuel injection to the mix of these innovations and you'll agree: backward is the right way forward.
