Engine & Performance

At the heart of the YZ250X is a 249cc liquid-cooled 2-stroke single with reed-valve induction, fed by a Hitachi Astemo Keihin PWK38S (38 mm) carburetor. While Yamaha does not publish power or torque figures for this model, the combination of a 2-stroke, a 38 mm carb, and a relatively light wet weight suggests a responsive, eager feel that rewards throttle control—ideal for threading through tight single-track and accelerating between corners.

The constant-mesh 5-speed gearbox and multiplate wet clutch keep things simple and durable for race-day intensity or weekend loops. With a 1.8 gal (≈6.8 L) tank, the focus is squarely on competitive stints and spirited sessions rather than long-distance liaison sections. If you’re cross-shopping four-strokes, the YZ250X provides a different kind of fun: snappier revs, a lighter overall package, and that classic 2-stroke character.

Handling, Comfort & Yamaha YZ250X Seat Height

The chassis is an Aluminum YZ250-spec frame, paired with enduro-ready geometry: 27.7° rake and 4.8 in trail, with a 58.5 in wheelbase. On the trail, this setup aims to balance nimble turn-in with stability across roots, rocks, and chopped-up race lines. The Yamaha YZ250X weight is a claimed 229 lb (≈104 kg) wet, which contributes to quick direction changes and less fatigue in tight sections.

Suspension is fully adjustable at both ends: a KYB Speed-Sensitive System 48 mm inverted fork with 11.8 in of travel up front and a KYB single shock with 12.4 in of travel at the rear. That kind of travel, combined with a 14.2 in maximum ground clearance, gives you room to charge over obstacles and keep momentum when the terrain turns ugly.

The Yamaha YZ250X seat height is 38.4 in (975 mm). Taller riders will appreciate the roomy cockpit and ability to transition from seated to standing quickly. Shorter riders may find the height challenging at first, but the low overall weight helps with balance at low speeds and when pivoting the bike on off-camber sections.

Who Is the 2026 Yamaha YZ250X For?

This bike is aimed at enduro and cross-country riders who prefer the immediacy and feel of a 2-stroke. If you’re chasing a lightweight woods weapon with fully adjustable suspension and a competition-ready chassis, the YZ250X fits the bill. The 38.4 in (975 mm) seat height and lively 2-stroke response may challenge true beginners, but experienced riders and ambitious intermediates will appreciate its precision and punch. With a 1.8-gallon tank and a short factory warranty, it’s clearly built for performance-focused rides rather than daily commuting.

Torquepedia Verdict

The 2026 Yamaha YZ250X leans into what makes two-strokes great off-road: low weight, a sharp chassis, and straightforward maintenance. Its KYB suspension, serious ground clearance, and quality brake package give it the control and confidence racers and fast trail riders demand.

Weaknesses? Seat height will be tall for some, the fuel tank favors sprints over distance, and Yamaha doesn’t publish power or torque figures. Still, judged on the 2026 Yamaha YZ250X specs, this is a compelling, no-nonsense enduro tool in the 250 class.
