SX VENOM

Pulling from Yamaha’s Enticer 340, the SX Venom was engineered with growth in mind. The fuel-injected, electric-start, two-stroke 397cc single-cylinder engine is propelled by a 121-inch Camso Hacksaw track. Long-travel 'Dual Shock' rear suspension, lightweight alloy chassis, Stryke single keel skis and racy styling are combined in a lightweight sled that’s perfect for anyone in the family to go for a rip! It’s guaranteed fun for young, new and returning riders.


 

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 a smooth, wide range of power.
Performance
The compact power plant weighs in under 50 pounds packing a mighty punch with its class leading horsepower-to-weight ratio.
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.
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.
