YZ250X

The YZ250X is a two-stroke weapon developed specifically for off road racing. It is designed to appeal to riders who favour the sharp handling, instant power delivery and simple maintenance of a fast revving powerplant. Industry leading twin chamber speed sensitive KYB suspension is a bonus for enduro racing.

YZ250X features include an 18-inch rear wheel, sealed O-ring chain, wide ratio transmission, narrow expansion chamber, off-road focused tyres and suspension settings, a sidestand and fuel tank petcock with reserve position.

The two-stroke will be available with an optional cross country rec rego kit which is expected to prove popular in states that offer recreational registration.

Features
YZ250 power tuned for off road

Legendary YZ250 249cc liquid-cooled reed-valve-inducted two-stroke engine, a new compression ratio, new exhaust port timing, updated CDI unit – all focused on making a wide, controllable power character ideal for off road racing.

Revised power valve

Patented Yamaha Power Valve System – now with broader opening timing for even smoother power – combines bottom-end acceleration with strong midrange and eye-opening top-end.

Compact exhaust pipe

New exhaust expansion chamber is designed especially for the new YZ250X, and is narrower both horizontally and vertically for clearance on tight, technical trails, while still providing excellent exhaust efficiency.

Advanced carburettor

38mm Keihin® PWK carburetor with throttle position sensor provides precise fuel/air mixing and crisp throttle response throughout the powerband.

Racing intake system

Special-design carbon fibre reed-valve petals improve throttle response and engine performance across the entire rpm range.

Wide-ratio gearing

Smooth-shifting, five-speed, wide-ratio transmission ensures proper gearing from tight woods sections to wide-open fire roads.

Updated digital ignition

Digital CDI ignition system delivers precise spark for faster, stronger response anywhere in the powerband, specifically tuned for the needs of the new YZ250X.

YZ250 cooling system

Large-capacity radiator features a ten-row core with four louvres for maximum cooling efficiency.

Proven braking performance

YZ250F-style front brake caliper with 270mm wave-style front and 245mm wave-style rear discs minimise unsprung weight and provide excellent stopping power.

YZ250 based frame

A carefully engineered, advanced aluminium frame and swingarm give the YZ250X the famous handling proven by the championship winning YZ250 motocross machine on tracks around the world. Tips the scales at just 104kg with all fluids – which makes it lighter than a four-stroke.

Industry-leading KYB fork

Industry-leading, fully adjustable KYB spring-type fork with speed sensitive damping uses piston speed to control damping force for super-precise handling and a smooth ride, with minimal wasted stroke or abrupt shocks for the rider – all tuned for the demands of off road racing.

Smooth KYB shock

Rear, fully adjustable KYB shock features 315mm of travel, separate adjusters for high- and low-speed compression damping, and a full lock oil rebound system for increased comfort, control and fantastic rear wheel traction.

Enduro-specific wheels and tyres

Cross-country-spec Dunlop Geomax AT81 tyres front and rear are ready to head straight to the races. An 18-inch rear tyre has a taller sidewall to improve comfort and reduce pinch flats.

Enduro ergonomics

A racy ‘gripper’ type seat and narrow fuel tank combine with a tapered aluminium handlebar and adjustable mounts to create greater freedom of movement and more comfortable ergonomics for riders.

Cross-country features

Off-road focused tyres with an 18in rear wheel, wide-ratio gearing, a standard side stand, sealed O-ring chain and a reserve fuel petcock. An optional lighting kit is available that assists in recreational rego in applicable states.

Optional rec rego kit

Headlight assembly, cowl and graphic; LED headlight globe; taillight; rear brake light switch; wiring harness, horn; amplifier/capacitor; handlebar switch; RHS mirror; brush guards; horn; stator; front brake line; front brake line upper guide.
