    397cc 2-stroke engine with EFI

    This 2-stroke unit is yet another industry first, its efficient EFI system helping it punch out very lively horsepower. With such a lightweight engine (under 22.7kg) partnering such a lightweight machine, the result is a power-to-weight ratio that promises high-level excitement all the way down the trails - and out into the back country. Pure fun!

    Ultra-lightweight chassis design

    The latest-technology alloy chassis has been designed to take full advantage of the responsive, free-revving engine. In development, the focus has been on saving weight without compromising strength and durability, enabling this innovative machine to offer very nimble handling, razor-sharp agility and a comfortable, balanced ride.

    Dual-shock rear suspension

    For exceptional handling in deep and steep stuff, our long-travel (12") system has a light but strong single-rail skid running down the track centre-line, with a skid frame that pivots at the mid-point. This single rail design is around 4.5kg lighter than a conventional dual rail system - and also reduces the build-up of heavy snow!

    Sleek, light 38" Independent Double Wishbone front suspension

    A direct descendent of our sleek Independent Double Wishbone suspension, this system is not only ultra-lightweight, but its compact design reduces the unwanted drag of suspension components in deep snow. The neutral stance delivers great manoeuvrability in tight terrain, while still showing polite and predictable manners on the trail.

    Mountain skis and lightweight spindles

    Light, forged aluminium suspension spindles and wide-spaced control arms give a large caster angle for tight turns and easy steering - a format specially designed to complement the wide 7" footprint of the high flotation, single-keel Yamaha Mountain skis. Unmatched handling precision in deep snow and on hard pack.

    146 x 2.0 Challenger track - for real grip

    Perfectly tuned to our compact-size SXVenom MTN and its single-rail skid-frame, the well proven Challenger track's 146 x 2.0 footprint lets you carve and hook like no other in its class. In fact, it delivers stunning performance in all conditions, with outstanding levels of deep-snow grip and propulsion.

    Tall bars & seat for easy handling

    The high seat and tall riser bar position - with mountain strap - give precise control over the agile chassis, as well as a very comfortable ride, while to change smoothly from sitting to standing is a breeze. The serrated running boards shed snow easily and give you great grip and confidence when standing.

    Electric starting & push-button reverse

    From the moment you step aboard, the fun can start, thanks to the turnkey electric starting and the supreme efficiency of the EFI system. Once you're out there in the deep powder, the simple, push-button electronic reverse system comes into its own to get you out of a tight spot. The audible 'beeper' warning helps with safer manoeuvring.

    Hand/thumb warmers & digital gauges

    Practical luxuries are a well-known Yamaha snowmobile speciality. Examples are the adjustable hand and thumb warmers, which are comfortingly standard, while our compact and stylish digital gauge keeps you informed with clear displays of rpm, speed, fuel and hours run, as well as important engine data.
