Yamaha Motor Corporation, USA, unveiled the 2021 off-road motorcycles, including the YZ cross country models including a redesigned 2021 YZ450F, and their reliable Trail dirt bikes. The bikes will be hitting dealer floors soon.
“Yamaha’s cross country lineup builds on the unmatched success of our motocross designs, using industry-leading technology to provide uncompromised performance for cross country competition,” said Derek Brooks, Yamaha Motorsports Motorcycle Product Line Manager. “The newly redesigned YZ450FX provides a lighter, more powerful, and better handling off-road experience for both cross country racers and recreational riders alike.”

Other chassis components such as engine mounts, top triple clamp and front axle, as well as the class-leading KYB® suspension with enhanced compression and rebound characteristics were carefully refined to reduce weight while improving handling and performance. To bring the new package to a stop, the 2021 YZ450FX features a newly designed front brake caliper, brake pads and front and rear disc.
To further showcase the YZ450FX’s cross country edge, electric start, a lightweight lithium battery, and advanced fuel injection are all standard features. The front-positioned intake and rear-positioned exhaust layout deliver the widest spread of reliable power while balancing the weight for excellent mass centralization. This cross country machine also continues to feature Yamaha’s advanced racing technology. The dual-mode switchable engine mapping and wireless connectivity is handled through the industry’s only free-of-charge complete tuning system, highlighted by the Yamaha Power Tuner App, which allows racers to adjust their engine performance right from their phone.

With 40 years under its belt, the 2021 PW50 continues to be one of the best trail bikes for first-time riders. After making its debut, the PW50 established itself as the go-to bike for children just learning how to ride off-road.
