YZ450F

The Yamaha YZ450F takes motocross performance to the next level. At its core is a high‑revving 450 cc liquid‑cooled DOHC four‑stroke single‑cylinder engine with 97.0 mm bore × 60.8 mm stroke and a 13.0 :1 compression ratio. With a 44 mm Mikuni fuel‑injection throttle body, it unleashes aggressive power while remaining rideable, giving top‑tier racers the edge they demand.

Chassis and suspension have been refined for 2026 to deliver both agility and high‑speed stability. The bilateral‑beam aluminium frame has been sharpened, and the KYB® spring‑type fork with Speed Sensitive System (up front) and a fully adjustable KYB monoshock at the rear give excellent control over 12.2″ front travel and 11.6″ rear travel. The bike’s seat height at around 38″ (≈ 965 mm) and the compact footprint allow experienced riders to manoeuvre confidently across the track.

Electronics are firmly race‑focused. With Yamaha’s Power Tuner app compatibility, adjustments to engine mapping, traction and launch control are made on the fly from your phone. Whether you’re dialling in response for a gnarly whoop section or reacting to changing track conditions, the YZ450F puts advanced tools in your hands.

The bodywork emphasises mass‑centralisation and rider mobility: slim shrouds, high fenders and low centre of gravity keep the bike agile. On the track, it translates to sharper cornering, quicker direction changes and confidence‑inspiring feedback.

For riders who demand championship‑grade hardware without compromise, the 2026 Yamaha YZ450F delivers. It’s not just a motocross machine — it’s a complete package of engineered power, precision handling and cutting‑edge tuning capability. Step up to the YZ450F and ride to win.
