The 2021 Yamaha YZ250F features a thoroughly refined engine, revised frame, new suspension settings and brakes to deliver more class-leading power and offer a superior balance of nimble, yet confidence-inspiring handling.

Available in Team Yamaha Blue and the Monster Energy Yamaha Racing Edition, the latest YZ250F has a new cylinder-head with an improved intake port shape and new camshaft profiles, as well a new air-box and intake track, a new silencer and an updated ECU. These modifications, along with other refinements like an updated transmission and shift cam, a revised clutch design and improved water pump impeller, all help to produce stronger mid to top-end power and increased peak power, while retaining its class-leading low-end torque.

Tuned specifically for the 2021 YZ250F, the updated lightweight aluminium, bilateral beam frame and new engine mounts have been redesigned with all-new flex characteristics to improve bump absorption, traction and cornering performance. The industry-leading, fully-adjustable KYB coil spring-type fork with enhanced speed-sensitive damping provides an exceptional balance between comfort and bottoming resistance while the link-type rear suspension features a KYB shock with revised damping characteristics to match the updated chassis.

Other chassis components such as the top triple clamp, handlebar mounts and front axle were also redesigned to complement the new frame. Improved braking performance is achieved with newly engineered lighter weight front and rear brake calipers, larger surface area brake pads and redesigned 270mm front and 240mm rear discs.

Standard equipment includes electric start, a lightweight lithium battery, advanced fuel injection, a front-positioned intake, and rear-positioned exhaust layout to deliver the widest spread of power with reliable performance while balancing the weight for excellent mass-centralisation. Racers can adjust their engine performance straight from their phone using the onboard wireless connectivity through the complete tuning system, which is highlighted by the Yamaha Power Tuner App.

The new 2021 YZ250F will be available from dealers this September in next-generation Team Yamaha Blue for $8299 MSRP. The Monster Energy Yamaha Racing Edition will be available from dealers in September for $8499 MSRP.

The 2021 YZ450F returns with all of the class-leading features first introduced on the current model. 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.

The 2021 YZ450F will be available from dealers this month in next-generation Team Yamaha Blue for $9399 MSRP. The Monster Energy Yamaha Racing Edition will be available from dealers in August for $9599 MSRP.

Yamaha’s YZ125 and YZ250 models return for 2021 to complete Yamaha’s full-size line-up of motocross bikes. With their modern styling, lightweight aluminium frame and industry-leading KYB Speed Sensitive System front forks and KYB fully-adjustable rear shock, the 2021 YZ125 and YZ250 continue their outstanding performance and durability with a rider-friendly chassis and race-ready features.

The 2021 YZ125 will begin arriving at Yamaha dealerships in August, while the YZ250 will be available from dealers this month. Both models will be available in next-generation Team Yamaha Blue for $6599 and $7499 MSRP.

Yamaha’s 2021 youth models are once again ready to tackle the track. The YZ65 and YZ85/LW are powered by confidence-inspiring 65cc and 85cc two-stroke engines. Featuring the Yamaha Power Valve System, these engines deliver a broad spread of power and torque across the entire rev range, without losing any power at high RPM.

Fully adjustable, industry-leading 36mm KYB spring type forks and KYB rear shock contribute to class-leading handling and performance in a wide range of conditions. Four-way, adjustable handlebar positioning, as well as lever-reach adjustability are designed for ultimate rider comfort, regardless of size. Finally, with two-stroke ease of maintenance and Yamaha’s proven durability, the 2021 YZ85/LW and YZ65 are built to keep kids on the track.

The 2021 YZ65 and YZ85 will both be available from dealers this month in next-generation Team Yamaha Blue for $4599 and $4699 MSRP, respectively.
