MARIETTA, Ga., June 03, 2026 (GLOBE NEWSWIRE) -- Yamaha Motor Corporation, USA, has announced its all-new 2027 YZ250F, adopting significant changes including an all-new engine and chassis designed to make the class-defining middleweight champion even better. The YZ250F is the proven class leader in the 250cc segment, earning more shootout wins in top MX publications than any of its competitors, and helping propel current West and East Supercross champions Haiden Deegan and Cole Davies to their 250cc title sweep this season. The YZ250F dominated the Supercross season, winning an astounding 16 out of 17 Main Events.
“The 2027 YZ250F receives a completely redesigned engine and extensive chassis changes to provide the highest level of performance for winning races,” said Derek Brooks, Yamaha Motorsports Motorcycle Product Line Manager. “The balance of increased power and improved handling characteristics have pushed the bike to a new level of performance from weekend track riding to competitive racing at the highest level.”
An all-new engine has been designed for high-revving performance that delivers a linear engine response with more power and torque through the rpm range, increasing the rev limit by 700 rpm from the previous model. This was achieved through the adoption of a rocker arm with finger follower system derived from Yamaha’s SuperSport YZF-R1, and intake refinements that allow for increased airflow and higher revs. Despite the increase in power, revisions to the air cleaner box and exhaust systems help make the 2027 YZ250F noise-compliant, meeting FIM/AMA regulations with a tuned exhaust note that is both more pleasing and comfortable to the rider.
Transferring power to the rear wheel, an all-new hydraulic clutch design replaces the coil springs of the previous model with a new disc spring and integrates primary gear and basket into a single steel unit. The result is a more compact, lightweight and durable assembly which yields smoother, more consistent engagement, requiring less effort while eliminating the need for on-track adjustments.
The 2027 YZ250F adopts the same advanced aluminum bilateral beam frame as the YZ450F, delivering an unrivaled balance of rigidity and flex characteristics. The new inner and outer structure, including a thinner front downtube, provide improved stability, better cornering performance and a precise, confidence inspiring front-end feel. New engine brackets have been designed for optimized rigidity, improving comfort and straight-line stability with a more manageable character and a predicable response. These combined chassis updates result in greater usability in everything from slow, tight corners to high-speed sweepers and rough, rutty corner entries and exits, providing a motorcycle that’s easier to tip in, easier to choose and hold a line, with a higher level of overall handling performance.
A new high performance KYB® rear shock and revised fork setting tuned specifically for the YZ250F complement the new frame. The suspension combo provides enhanced damping force with less bump reaction and pitching movement. The updated shock also has a new hand-operated low-speed compression clicker for simplified trackside adjustments.
The rear braking system has gone through a significant overhaul, resulting in a lightweight compact design that delivers improved control with a linear buildup of stopping power. The rear brake caliper piston, the master cylinder piston and the rear brake disc were all reduced in size, with additional revisions to the brake line material and disc rotor bolts to reduce un-sprung weight. Even with reduced size and weight, the braking system retains progressive and strong stopping characteristics. In addition, the rear brake pedal tip also now uses bolt-type fasteners instead of rivets for simplified maintenance.
As part of the YZ250F’s evolution, styling cues are matched with the flagship YZ450F and now include a slimmer, more compact front number plate, new two-piece side covers, sharper rear fender and new YZ graphics. The honeycomb-pattern seat cover material also enhances rider movement on the motorcycle in various track conditions.
Finally, the industry-leading Yamaha Power Tuner app retains full functionality of the previous version and adds an ECU lock function for theft deterrence, allowing owners to prevent unauthorized engine start-up via a password-required lock accessed through the app.
