The Monster Energy Yamaha Factory Racing YZ450F is a production-based motorcycle, and the product of years of testing and development by Yamaha Motor Corporation engineers. In its original state, the YZ450F is a high performance motorcycle with plenty of ridable power and great handling characteristics. It is only when the YZ450F is placed in the hands of world class athletes, that upgrades and changes are needed. Every part that is changed on the Monster Energy Yamaha Factory Racing YZ450F serves the purpose of improving performance, or reducing weight.Engine performance is customized through the use of alternate camshafts, cylinder head porting, transmission ratios, and primary ratios.
A hydraulic clutch is adapted to the engine to eliminate the need for clutch adjustment during a race. A GET ignition system is used to allow for infinite engine mapping adjustment, to insure that the additional power is delivered with a smooth and easy to ride feel. Finally, Factory KYB suspension is used to supply the riders with the adjustability required to meet the demands of a Supercross track. The Monster Energy Yamaha Factory Racing Team continues to develop and test items throughout the year to ensure that the YZ450F delivered to the team’s riders, is of race winning performance and durability.
