Final Edition Badging 2025 Yamaha SXVENOM MOUNTAIN

A badge representing all 20,476 days Yamaha has been in the Snowmobile business. May it spark many conversations about the best sled, the coolest innovation, the longest ride. 

Yamaha Mountain Ski 2025 Yamaha SXVENOM MOUNTAIN

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 gnarly. The single keel design delivers light steering effort, yet confident and predictable handling on hard pack and in fresh fluff.

Mountain Single Beam Suspension 2025 Yamaha SXVENOM MOUNTAIN

The long 12-inch travel rear suspension features a lightweight single-rail design for easy directional change with exceptional carving ability in the deep and steep. The advanced skid frame features a single pivot at the midpoint of the rail that runs down the centreline of the track. The single rail is over 10 pounds lighter by design and doesn't trap snow compared to conventional dual-rail suspensions keeping the sled much lighter in real-world conditions.

features and benefits

TOP

  • 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, battery-less 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.
  • The alloy chassis was designed to keep the weight down using minimal parts with no compromise to its durability or function.
  • A compact digital gauge gives the rider speed, RPM, fuel level, hours and distance at a glance. There are also light indicators to warn against any oil or engine temperature issues.
  • The long 12-inch travel rear suspension features a lightweight single-rail skid to provide exceptional handling in the deep and steep. The advanced skid frame features a single pivot at the midpoint of the rail which runs down the centreline of the track. The single rail is over 10 pounds lighter by design and doesn't trap snow compared to conventional dual-rail suspensions keeping the sled much lighter in real-world conditions.
  • A durable Challenger track teams up with the single-rail skid frame to carve and hook like nothing else in its class. Based on the reduced weight and size of the SX Venom Mountain, the 146-inch track has the perfect footprint to go anywhere.
  • The sensor monitors cylinder vibration to signal ECM in the event of combustion detonation due to improper fuel or running conditions. Timing is adjusted to help prevent engine damage.

PERFORMANCE

  • The power valve system tunes the exhaust port opening based on RPM to ensure maximum torque and fuel efficiency across the power band.
  • Electronic fuel injection provides efficient fuel delivery to the cylinder based on engine RPM for maximum torque and response. The computerized fuel injection ensures reliable cold weather starting, maximum fuel range with low exhaust gas emissions.
  • 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.
  • The strong Hayes hydraulic 'Stealth' brake master-cylinder is equipped with a composite Stealth brake lever and lightweight caliper to provide great modulation for better feel and powerful stopping performance.
  • The compact power plant weighs in under 50 pounds packing a mighty punch with its class leading horsepower-to-weight ratio.
  • With alloy bulkhead and tunnel heat exchangers, the engine stays cool when things heat up.

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.
  • The 4.5-inch riser block positions the hooked end bars with mountain strap within easy reach whether seated or standing.
  • Derived from the sleek SRV-M front suspension, this lightweight design is ultra-compact to reduce unwanted spindle and suspension component drag in deep snow. The neutral stance allows for great maneuverability in tight terrain along with predictable manners on the trail. The lightweight, forged aluminum spindles join the widely spaced upper and lower control arms producing a large caster angle for tight turning and ease of steering.
  • The lightweight running boards are designed to shed snow and are serrated to give good hold when standing for confident manoeuvrability.

COMFORT

  • Almost a thing of the past, having a modern snowmobile with the weight of a 30-year-old fan-cooled sled opens the door for a whole new era in snowmobiling function and fun.
  • A simple push of a button causes the engine to restart in reverse. The audible 'back-up' beeper indicates the reverse system is engaged and continues to beep until the button is pushed again to restart the engine in its forward direction. A simple, lightweight and efficient way to back out of a tight situation.
  • Standard handlebar and throttle lever warmers are included.
  • The large 10.4-gallon / 39.7-litre fuel capacity coupled with the frugal demand of the mid-sized, EFI engine, means extended operating range for the Venom Mountain.
  • Turnkey electric starter combined with electronic fuel injection provides quick and reliable ignition in all conditions.
  • The four-inch 'race' screen is just enough to deflect the snow away from the console.
  • The seat design offers easier transition from seated to standing. Side-to-side movement is also made easier with its tapered sides to aid in maneuverability both on- and off-trail.
  • Twin-tube shocks provide ample adjustment and ride comfort.
