2026 Yamaha YZ250F Specs & Review

Yamaha’s quarter-liter motocrosser continues to target riders who want a sharp-handling, high-revving 4-stroke that’s easy to dial in for race day. The 2026 Yamaha YZ250F specs highlight a modern chassis, proven KYB suspension, and app-enabled electronics that make setup straightforward. This Yamaha YZ250F review breaks down the numbers and what they mean on track.

Key Specs at a Glance

• Displacement: 250 cc
• Engine type: 250cc liquid-cooled DOHC 4-stroke; 4 valves (1 cylinder)
• Power: Not listed
• Torque: Not listed
• Wet weight: 231 lb / 105 kg
• Seat height: 38.2 in / 970 mm

Engine & Performance

The YZ250F uses a 250 cc, liquid-cooled DOHC 4-stroke single with 4 valves, a high 13.8:1 compression ratio, and an oversquare 77.0 mm × 53.6 mm bore and stroke. That combo traditionally favors fast revs and strong pull through the middle and top, the sweet spot for rhythm sections and deep berms. Fueling comes from a Mikuni 44 mm fuel injection system, and drive goes through a constant-mesh 5-speed with a multiplate wet clutch to a chain final drive.

Yamaha bundles helpful electronics: the Yamaha Power Tuner App, Traction Control, and Launch Control with an adjustable rpm limiter you can set between 6,000–14,000 rpm via the app. Being able to tailor launch rpm and add a layer of traction management is a real advantage when gates drop on slick starts or hardpack. While the provided 2026 Yamaha YZ250F specs don’t list power or torque figures, the chassis and electronics indicate a motor built to be ridden aggressively and kept on the pipe without drama.

Handling, Comfort & Yamaha YZ250F Seat Height

The aluminum bilateral beam frame is paired with KYB’s Speed-Sensitive System inverted fork (fully adjustable, 12.2 in travel) and a fully adjustable KYB rear shock (12.3 in travel). That suspension package has a well-earned reputation for support and predictability, and the geometry backs it up: a 26.9° rake, 4.7 in (119 mm) trail, and a 58.1 in wheelbase strike a balance between quick turn-in and straight-line stability.

The Yamaha YZ250F seat height is 38.2 in (970 mm), which is typical for a full-size MX bike. Taller riders will appreciate the roomy stance and 13.8 in (351 mm) of ground clearance when skimming whoops or clearing ruts. Shorter riders may find mounting and dabbing a foot more challenging, but the well-centered Yamaha YZ250F weight of 231 lb (105 kg, wet) helps low-speed maneuvering in the pits or tight off-road sections. Dunlop Geomax MX33 tires (80/100-21 front MX33F, 110/90-19 rear) come ready for intermediate terrain, giving predictable bite across a wide range of track conditions.

Who Is the 2026 Yamaha YZ250F For?

If you race local MX or cross-train on practice tracks and off-road parks, this package is right in the pocket: a rev-happy 250 4-stroke, serious KYB suspension, and useful electronics. Intermediate and experienced riders will get the most from the chassis and adjustability, while ambitious beginners who fit the tall seat can grow into it thanks to Traction Control and app-enabled setup.

It’s built for motos rather than commuting or dual-sport use. The 1.6 gal (6.1 L) tank, 38.2 in seat height, and focused geometry favor gate drops, sprint laps, and repeated sessions over long-distance trail exploration.

Torquepedia Verdict

The 2026 Yamaha YZ250F specs tell a clear story: a race-focused 250 with excellent suspension travel and tuning range, strong brakes, and smart electronics that matter when conditions change. The KYB SSS hardware, aluminum bilateral beam frame, and balanced geometry give it the precision and stability riders expect in this class.

Weaknesses? The tall seat and limited fuel capacity are inherent to modern MX bikes, and the lack of published power/torque in the provided data means you’ll judge performance by lap times rather than dyno sheets. Still, with 231 lb (105 kg) wet weight, stout brakes, and traction/launch aids, it’s a compelling pick for riders focused on progression and podiums.
