Detailed: 2026 Yamaha YZ range

New generation YZ450F headlines latest motocross line-up.

Yamaha has uncovered its 2026 YZ motocross line-up, headlined by significant updates to a new generation YZ450F, in addition to a series of 70th Anniversary Edition YZ models.

Leading the charge is the 2026 Yamaha YZ450F, which has received a series of targeted updates aimed at improving rideability, comfort, and chassis balance – without compromising its race-proven performance. Building on the comprehensive platform introduced in 2023, this year’s model refines the formula with both mechanical and electronic improvements.

Most notably, the YZ450F now features a new hydraulic clutch system, replacing the previous cable-actuated unit. This delivers more consistent lever feel throughout long motos and adds durability under heavy load. The clutch feel has also been enhanced with a revised action and lighter pull, improving rider control in technical sections and under acceleration.

Yamaha has redesigned the intake port for improved combustion efficiency and low-to-mid-range power delivery. The airbox and muffler now include resonators designed to reduce intake and exhaust noise, while smoothing out the throttle response for a more controlled power curve. While peak power remains strong, the overall delivery is more linear and manageable – particularly helpful in rough, rutted conditions where precision matters most.

Chassis-wise, the aluminum bilateral beam frame has been revised for 2026, featuring updated downtube thickness and a new one-piece forward engine mount. These changes are designed to boost front-end feel and improve rider connection with the track, especially during braking and high-speed corner entries.

The KYB suspension package has also been refined. The rear shock gains a larger base valve and six-port main piston to enhance mid- and high-speed damping characteristics. Yamaha has also added a tool-free compression damping adjuster, making on-the-fly changes easier. Up front, the KYB Speed-Sensitive System fork receives new valving for improved initial stroke sensitivity and better bottoming resistance – refinements made with feedback from pro-level racing.

Ergonomics have been subtly upgraded, too. The seat now features a new anti-slip cover, and the bodywork remains slim, minimalist, and race-focused, allowing for fluid rider movement and easy grip across all styles of riding.
The Power Tuner App continues to be a cornerstone of the YZ450F package. For 2026, it includes an ECU lockout function, preventing unintentional map changes during riding. Riders still have full control over traction control, launch control, fuel and ignition mapping, and lap timing – all from their smartphone.

Also receiving notable attention this year is the YZ125, Yamaha’s long-standing 125cc two-stroke designed for rising talent and aggressive lightweight riders. For 2026, the YZ125 benefits from revised suspension settings and updated graphics. The KYB components have been tuned for improved bump absorption and cornering consistency, particularly for lighter riders.

While the 125’s engine package remains largely unchanged, Yamaha has carried forward the recent enhancements to intake volume and power valve tuning, giving the YZ125 a stronger bottom-end pull while maintaining its high-revving character. The lightweight chassis, sharp ergonomics, and race-ready feel continue to make the YZ125 a key player in the youth and amateur racing scenes.

The YZ250F is back with only minor adjustments. Following its recent platform update, the 2026 model carries over its bilateral beam frame, compact intake system, and high-revving DOHC engine. Suspension settings have been lightly revised for improved balance across varied track surfaces. Like the 450F, it continues to use the Power Tuner App, allowing for custom engine maps and ride data tracking.

Known as one of the most popular two-stroke 250s on the market, the YZ250 two-stroke returns in 2026 with updated graphics and colour schemes, while retaining the revised KYB suspension settings introduced recently.

The 2026 YZ450F is priced at $10,299, while the YZ250F comes in at $8,899. The 70th Anniversary Editions sit slightly higher – $10,499 for the YZ450F, $9,099 for the YZ250F, $8,299 for the YZ250 two-stroke, and $7,399 for the YZ125. Standard YZ two-stroke models are also available, with the YZ250 priced at $8,099 and the YZ125 at $7,199.
