Overview
The 2026 Yamaha YZ250F is a motocross bike in production for 2026. Its 249.0 cm³ single-cylinder, two-stroke engine makes 25 hp (19 kW), and the bike weighs 103.0 kg wet.
At 975 mm, the seat is high, which can make it harder for shorter riders to plant their feet at a stop. The 103.0 kg wet weight helps keep the bike manageable during low-speed maneuvering, while 360 mm of ground clearance suits rough terrain. Both KYB® suspension units are fully adjustable, and electric starting avoids kick-starting; the premix lubrication system means oil must be mixed with the fuel.
