Congratulations on your purchase!

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.

Good maintenance and regular service is key to keep your Yamaha in perfect condition and therewith to stay safe and reliable.

Yamaha’s Official Dealers are the best to perform such service since they receive dedicated training on our products regularly. Besides that, they have gained the best experience over the years with Yamaha products.

And when your Yamaha is serviced – make sure that Genuine Yamaha Parts and Yamalube products are used, since only these are 100% tested and approved by exactly the same engineers that created our fabulous two wheelers, ATV’s, outboards and other products.

Contact your local dealer for more details or check-out the ‘Yamalube’ section for the best oil and care products.
