Yamaha’s SX Venom Mountain gives mountain learners a great opportunity to enjoy the heights. The 397cc electronically fuel-injected two-stroke engine combines with a lightweight chassis to make the SX Venom a true viper that whistles through the mountain bowls! The Venom Mountain gets the same chassis as the Mountain Max, taking advantage of the unique single pivot point design to leave a 146″ footprint anywhere, anytime. Electric start, reverse gear and heated grips… all the goodies of a big sister, but in a dashing little package.
HIGHLIGHTS
This new 397cc high-tech engine boasts all the features you’d expect from a top-of-the-line snowmobile, including computerized ignition system (ECM), three-stage power boost valve in the exhaust port, battery-less fuel injection, electronic oil injection, and electric starter, just to name a few. The tuned exhaust pipe, enhanced with an exhaust detonation temperature sensor and a detonation sensor, ensures reliable performance. The lightweight crankshaft balance flywheel dampens unpleasant vibrations to deliver a wide range of power smoothly.
Yamaha minimized the number of parts in the design of the new alloy chassis to reduce weight without compromising durability or functionality.
At a glance on the digital dashboard, the rider knows the speed of his machine, the engine speed, the fuel level, the hours of operation and the distance traveled. Warning lights also alert the rider to low oil or abnormal engine temperatures.
The 305 cm (12 in.) long travel rear suspension has a single lightweight spar to dominate deep snow and steep grades. The advanced frame design has a single pivot point in the middle of the track, which is installed along the centerline of the track. Because this single-rail design offloads 4.5 kilograms and doesn’t accumulate snow like traditional dual-spar suspensions, the snowmobile is lighter in real-world conditions.
A highly durable Challenger track teams up with the unique spar suspension frame to track like no other snowmobile in its class. With the SX Venom Mountain’s low weight and small dimensions, the 146-inch track leaves a perfect footprint wherever it goes!
The sensor monitors cylinder vibration and communicates to the ECM if there is combustion accompanied by detonation caused by improper fuel metering or poor running conditions. In such cases, the ECM adjusts the ignition timing to prevent engine damage.
PERFORMANCE
Boost valves adjust the exhaust port opening based on engine speed to maximize peak torque and optimize fuel efficiency throughout the powerband.
Electronic fuel injection delivers fuel very efficiently to two injection points in the cylinder, depending on engine speed, maximizing torque and throttle response. Computer-controlled fuel injection provides reliable cold weather starting, maximizes range and delivers low exhaust emissions.
The CVTech Trailbloc drive pulley joins the CVTech Invance driven pulley to provide reliable clutch operation at low temperatures. The small diameter bearing allows the belt to sit lower in the primary drive pulley, resulting in a super low first gear ratio. This also creates a wider gear ratio in the secondary pulley, allowing every last drop of juice to be extracted from the compact engine.
The rugged Hayes “Stealth” hydraulic brake master cylinder is paired with a composite Stealth lever and lightweight caliper to provide excellent modulation, feel and braking power.
The compact engine tips the scales at only 22.7 kg (50 lbs), meaning it has plenty of energy to spare with its class-leading power-to-weight ratio.
Thanks to its apron and heat exchangers on the track housing – all made of alloy, the engine keeps its cool, even when things get hot!
MANIABILITY
Yamaha’s lightweight mountain skis deliver everything you need to waltz through deep snow. Their large 7″ (17.8 cm) footprint helps increase lift and actively raises the front section of the snowmobile when gliding through deep powder. Traction bars on the top of the skis provide a solid footing when the ride gets really rough. The unique keel design translates into effortless steering and predictable handling – in both fresh powder and hardpack.
The 11.4 cm (4.5″) handlebar-mounted flange places the J-tips on the handles and the climbing strap within easy reach, whether the rider is sitting or standing.
Derived from the streamlined SRV-M front suspension, this new lightweight, ultra-compact design reduces annoying drag from spindles and suspension components in deep snow. Neutral spacing allows for great maneuverability in tight terrain and predictable trail riding. Lightweight forged aluminum stub axles combine with generously curved upper and lower delta arms to provide a wide caster angle that’s ideal for attacking tight turns and easy steering.
Sharp serrations are cut into the lightweight running boards to keep the snow out of the way and to allow the rider to plant his feet firmly when standing, so that he can ride the white carpet with confidence.
CONFORT
It’s almost like a return to the past… A modern snowmobile with the weight of a 30-year-old fan-cooled snowmobile opens up a new era of functionality and fun.
To restart the engine and shift into reverse, simply push a button. The back-up alarm sounds once you’re in reverse, and the warning tone continues to sound until you push the button again to turn off the ignition and start moving forward. It’s a simple, lightweight and effective way to get out of a tight spot.
An adjustable handlebar and heating elements in the throttle are standard.
The 44-liter fuel tank, coupled with the fuel-injected engine that sips gas, means you travel far between fill-ups.
The electric starter combines with electronic fuel injection to bring the snowmobile to life every time and at lightning speed, in a myriad of conditions.
The 4-inch race-inspired windshield is just high enough to deflect snow off the console.

The seat is shaped to facilitate the transition from sitting to standing. The seat’s tapered edges also make it easier for the rider to move sideways, which increases maneuverability – both on the beaten path and in the great outdoors. Finally, the passenger seat is available as an option for two-up riding!
The double-walled amortos provide all the adjustment possibilities you need to adapt the comfort to your tastes.
