SX VENOM MOUNTAIN
Yamaha’s Venom Mountain is giving new mountain riders a reason to enjoy the altitude. The fuel-injected 397cc two stroke engine and lightweight chassis make the Venom Mountain more than capable of exploring that next bowl. Venom Mountain also gets the same chassis as the Mountain Max with the single pivot, single rail design allowing the 146” footprint to go anywhere, anytime. Electric start, reverse, hand warmers give you all the features of a big sled in a nimble little package. |
|
Mountain Single Beam Suspension
The long 12" travel rear suspension features a light-weight single rail skid to provide exceptional handling in the deep and steep. The Advanced skid frame features a single pivot at the mid point of the rail which runs down the center line of the track. The single rail is over 10lbs lighter by design and doesn't trap snow compared to conventional dual rail suspensions keeping the sled much lighter in real world conditions. |

|
Yamaha Mountain Ski
The lightweight Yamaha Mountain ski delivers everything you want in a deep snow ski. Its 7 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 deliver light steering effort yet confident and predictable handling on hard pack and in fresh fluff. |

Digital Gauge
A compact digital guage 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. |

- This new hi-tech 397cc engine has all the features you'd expect to find in a top of the line sled: Computerized ignition (ECM), 3-stage exhaust powervalve, battery-less fuel injection, electronic oil-injection and electric start to name a few. Tuned exhaust with EPTS (exhaust pop temperature sensor) and a detonation sensor combine to ensure reliable performance. A lightweight, counter balance shaft takes care of unwanted vibration delivering smooth, wide range power.
- The new alloy chassis was designed to keep the weight down using minimal parts with no compromise to its durability or function.
- A compact digital guage 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 light-weight single rail skid to provide exceptional handling in the deep and steep.The Advanced skid frame features a single pivot at the mid point of the rail which runs down the center line of the track. The single rail is over 10lbs 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 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 at two different injection points in 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 provides reliable, low temperature operation with wide ratio performance. The small diamter 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 lbs packing a mighty punch with its class leading, HP/Weight ratio.
- With alloy bulk-head and tunnel heat exchangers, the engine stays cool when things heat up.

- The lightweight Yamaha Mountain ski delivers everything you want in a deep snow ski. Its 7 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 deliver 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 new 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 light-weight running boards are designed to shed snow and are serrated to give good hold when standing for confident manouverability.
