Engine & Performance

The WR450F’s 450cc liquid-cooled DOHC single is built for tractable, controllable thrust in the rough. Its 97.0 mm x 60.8 mm bore and stroke, combined with a high 13.0:1 compression ratio, give the bike the punch and response experienced riders expect from a modern big-bore enduro. Mikuni fuel injection with a 44 mm throttle body keeps fueling crisp, and the electric starter (lithium‑ion battery) makes restarts painless in tight, technical sections.

Real-world delivery is enhanced by Yamaha’s three‑level Traction Control via the Yamaha Power Tuner app, letting you tailor grip for slick roots, hardpack, or sandy whoops without overcomplicating the cockpit. An industry‑first ECU lock (2026) adds peace of mind. The wide‑ratio 5‑speed gearbox spreads the usable range—low enough for slow, clutch-controlled climbs and steady enough for fast transfer sections. Practical touches like a sealed drive chain, a composite engine guard, and a radiator fan are built for long days in hot, slow terrain, while a spark arrestor, headlight, and taillight broaden trail access and low-light usability.

Handling, Comfort & Yamaha WR450F Seat Height

The chassis uses an aluminum bilateral beam frame for a firm yet communicative feel. Up front, a KYB spring‑type fork with full adjustability delivers 11.8 in (300 mm) of travel, paired with a fully adjustable KYB single shock offering 12.0 in (305 mm) at the rear. The geometry—26° rake and 4.3 in (109 mm) trail (USA listing) with a 57.9 in (1470 mm) wheelbase—strikes a balance between high-speed stability and the quick steering you need to thread between trees.

Ground clearance is a generous 13.0 in (330 mm), which, combined with the robust skid protection, encourages attacking rock ledges and rutted climbs. The Yamaha WR450F seat height is 37.6 in (955 mm), very much in line with serious enduro machinery. Shorter riders may want to plan for a dab in off-camber sections, while taller riders will appreciate the roomy cockpit for aggressive body positioning. The Yamaha WR450F weight is 258 lb (117 kg) wet—planted enough for stability in choppy terrain, yet manageable for pivot turns and trail-side maneuvering.

Tire spec varies by region: US models feature an 80/100‑21 Dunlop Geomax MX33F front and 120/90‑18 Dunlop Geomax MX33 rear, while AU ADR listings show 90/90‑21 54R front and 140/80‑18 70R rear. Overall dimensions come in at 85.4 in x 32.5 in x 49.8 in (2170 x 825 x 1265 mm), a familiar footprint for a full-size enduro.

Equipment & Features

Braking duties are handled by Nissin: a 270 mm hydraulic disc up front and a 240 mm disc out back, offering strong bite and predictable modulation. Suspension is a highlight—fully adjustable KYB components front and rear give you ample tuning headroom for roots, rocks, and high-speed chop.

Tech-forward touches set the WR450F apart. Three‑level Traction Control via the Yamaha Power Tuner app lets you tune to conditions, and the (2026) ECU lock adds a layer of security. A radiator fan helps keep temps in check during slow, technical climbs. Trail essentials include a sealed drive chain, composite engine guard, spark arrestor, headlight and taillight, and a kickstand. Fuel capacity is 2.0 gal (approx. 7.6 L; AU listing 7.4 L), suitable for race loops and spirited trail rides. US MSRP is $10,299 with a 30 Day Limited Factory Warranty; AU ride‑away (MY26) is AUD 18,699 (incl. GST; varies by dealer/region).

Who Is the 2026 Yamaha WR450F For?

This bike targets experienced off‑road and enduro riders who want a durable, tunable package with race-proven suspension and thoughtful trail hardware. The tall seat and full-size stance favor riders comfortable with a 450-class enduro. It’s built for woods racing, desert scrambles, and weekend singletrack—not daily city commuting—though the headlight and taillight make dawn and dusk rides more practical. As always, check local regulations for registration and trail requirements.

Torquepedia Verdict

The 2026 Yamaha WR450F blends a premium KYB suspension package, robust aluminum frame, and useful electronics into a cohesive, hard-charging trail weapon. Standout features include the three‑level Traction Control (app-tunable), radiator fan, and the (2026) ECU lock—thoughtful additions that complement its already proven chassis and engine package.

On the flip side, the 2.0 gal (approx. 7.6 L) tank is modest for long-distance adventuring, and the 37.6 in (955 mm) seat height won’t suit every rider. Still, with a US MSRP of $10,299 and a wet weight of 258 lb (117 kg), the WR450F remains a compelling pick for riders who want a serious enduro straight from the crate.
