SX VENOM MOUNTAIN

Ready for an alpine adventure? Yamaha’s Venom Mountain is your snowmobile. Go ahead and explore that next bowl with Mountain Single Beam skid frame with single-pivot, single-rail design. It allows the 146-inch footprint to go anywhere, anytime. Electric start, reverse and hand warmers give you all the features of a big sled in a nimble lighter package. The compact fuel-injected 397cc two-stroke engine and lightweight chassis make for maximum maneuverability.


 

Top Features
This high-tech 397cc engine has all the features you'd expect to find in a top-of-the-line sled: computerized ignition (ECM), three-stage exhaust power valve, batteryless fuel injection, electronic oil-injection and electric start to name a few. Tuned exhaust with an exhaust pipe temperature sensor (EPTS) and a detonation sensor combine to ensure reliable performance. A lightweight, counterbalance shaft takes care of unwanted vibration delivering smooth, wide-range power.
Performance
The CVTech Trail Bloc drive clutch and Invance driven clutch system provides reliable, low temperature operation with wide-ratio performance. The small diameter main bearing allows the belt to sit lower in the primary, for a super low first gear. This also creates a wider ratio transmission through the secondary pulley, to efficiently pull every pony out of the compact engine.
Handling
The lightweight Yamaha Mountain Ski delivers everything you want in a deep snow ski. Its seven-inch wide footprint enhances flotation and actively lifts the sled’s nose up on plane in deep powder. Traction lugs on the top of the ski give you a sure foothold when the situation gets really gnarly. The single keel design delivers light steering effort yet confident and predictable handling on hard pack and in fresh fluff.
Comfort
Twin-tube shocks provide ample adjustment and ride comfort.
