2025 Yamaha SX Venom

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 era in snowmobiling function and fun.
• The seat design offers mobility for aggressive cornering, transitioning through the bumps and comfort for the long haul.
• The four-inch 'race' screen is just enough to deflect the snow away from the console.
• Turnkey electric starter combined with electronic fuel injection provides quick and reliable ignition in all conditions.
• The large 10.6-gallon fuel capacity coupled with the frugal demand of the mid-sized, EFI engine, means extended operating range.
• Standard handlebar and throttle lever warmers are included.
• 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.

Handling

• The Yamaha designed single keel ski strikes the elusive balance between lightweight steering effort and precision handling over a wide range of snow conditions. Special, carbides further enhance steering response. An adjustable shim pad assembly works in conjunction with the rubber saddle block to tune the carbide pressure point. Overall ski stance is also adjustable by relocating the thick spacer located on each ski axle to the opposite side.
• The 4.5-inch riser block positions the hooked end bars 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 maneuverability.

Performance

• The compact power plant weighs in under 50 pounds packing a mighty punch with its class leading horsepower-to-weight ratio.
• 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.
• 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 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 power valve system tunes the exhaust port opening based on RPM to ensure maximum torque and fuel efficiency across the power band.

Top Features

• FINAL EDITION BADGING: 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.
• 121 X 14 CAMSO 'HACKSAW' TRACK: The lightweight 121-inch track is slightly narrower (14 inch) with shorter (1 inch) lugs for agility and balanced handling, helping make the sled feel as light and sporty as it looks.
• ELECTRONIC REVERSE: 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.
• 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 a smooth, wide range of 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 detonation 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.
• Torsion springs and twin-tube shocks combine to offer 10.7-inches of rear suspension comfort.
• The lightweight 121-inch track is slightly narrower (14 inch) with shorter (1 inch) lugs for agility and balanced handling, helping make the sled feel as light and sporty as it looks.
