The off-road motorcycle market has seen significant updates from Yamaha, as the company has refreshed its 2027 competition range. The main focus of these updates is on the YZ250F, which now boasts a brand-new engine and chassis. This change promises to deliver more power and torque across the entire rev range, making it an attractive option for competitors in the off-road racing circuit.
The new engine features a higher rpm limit by 700rpm compared to its predecessor, indicating improved performance and responsiveness. Additionally, the rocker arms have been sourced from Yamaha's flagship superbike, the R1, while the intake valve springs now feature a double-spring design.
This is the first time this valve system has been used on a YZ off-road series model, showcasing Yamaha's commitment to innovation and improvement in its competition range. The camshaft has also been redesigned with a larger shaft diameter, further enhancing performance.
The drivetrain has undergone significant changes, while some weight reduction has also been achieved through the use of lighter components. The hydraulic clutch, taken from the 2026 YZ450F, now offers more load than before and provides improved reliability.
In terms of aesthetics, the new YZ250F takes after its bigger sibling, the YZ450F, with regards to graphics. This cohesive design approach ensures a seamless transition between models within the range.
The updated 2027 YZ85 model also boasts engine and chassis updates, resulting in better rideability and reliability compared to its predecessor. Changes to the Yamaha Power Valve System (YPVS) have been made to produce more power at lower rpm.
Furthermore, the YZ85 is now available in an Icon Blue colourway, while new graphics and a compact handlebar pad add to its appeal. The youth racing machine, the YZ65, has also received several updates, including a new handlebar pad, front wheel bearings, and seat skin.
The 2027 off-road competition range includes updated models such as the YZ450F, YZ250, and YZ150, although pricing across the entire range remains to be confirmed.
Yamaha's commitment to innovation and improvement is evident in its refreshed competition range. As competitors gear up for the upcoming racing season, Yamaha's new off-road motorcycles are poised to deliver exceptional performance and reliability.
The updated models promise to provide a competitive edge in the off-road racing circuit, with their improved power, torque, and handling capabilities. With Yamaha's dedication to innovation, fans of the brand can expect exciting developments in the years to come.
