2021 Monster Energy Yamaha Racing Edition

Featuring official Monster Energy Yamaha Factory Team graphics as well as exclusive black & blue bodywork and matching blue wheels, it’s the ultimate production Yamaha race bike. 


The 2021 YZ450F returns with all of the class-leading features first introduced on the 2020 YZ450F, including an updated engine, cylinder head, frame and technology features for a lighter, more powerful and better handling motocross experience.


Racers can achieve quicker, smoother race starts through Yamaha’s Launch Control System, adjust their on-track performance using the onboard wireless connectivity through the free of charge Yamaha Power Tuner App right from their phone, and choose between two user-defined ECU maps on the fly through the handlebar-mounted dual-mode engine map switch.
