The 2024 Yamaha YZ250F is a 250cc four-stroke motocross racer with significant updates from the chassis to the engine to the electronics. It is not an all-new model, but the changes reach almost every part of the bike, and it is priced at $8899.
The aluminum twin-spar frame is all-new and based on the YZ450F’s, with tweaks intended to enhance cornering and straight-line stability. The KYB Speed-Sensitive System fork returns with tool-free, knob-based compression damping adjustment, and the fork and shock get new settings to match the new frame for more stability on corner entry and exit.
The engine’s intake path is smoother thanks to the new frame and bodywork, and the airbox is lowered. New ECU settings go with the intake changes, aimed at improving midrange-to-high-rpm power. A 5-speed transmission and chain final drive put that power to the ground.
Electronics are a big part of the update. The smartphone-based Yamaha Power Tuner app allows wireless adjustment of the air/fuel mixture and ignition timing with slide bars, tracks maintenance-related engine data, and includes a suspension setup guide, though the suspension itself is not adjusted through the app.
Traction control has two levels plus off, with the ECU comparing wheel and engine speeds to optimize power delivery. Launch control is highly adjustable through the app, with an rpm limit from 6000 to 14,000 rpm in 500 rpm increments.
New bodywork and a new seat give the rider a flatter, narrower cockpit with more legroom. The fork has 12.2 inches of travel and the shock 12.3 inches, the seat height is 38.2 inches, and the YZ250F rolls on Dunlop Geomax MX33 tires. It comes in Team Yamaha Blue or as a retro-inspired 50th Anniversary Edition for $200 more.
