For model year 2025, my favourite mountain snowmobile from Yamaha is the SX Venom Mountain. This might surprise a few readers, because I usually gravitate towards the higher horsepower and wild handling sleds. You’re probably wondering, why I picked the 2025 SX Venom Mountain as my favourite. This sled made me smile, laugh, and feel like a kid again. It’s a great mountain sled to bridge the gap between the introductory 200 cc starter sleds for young kids and the full sized, and full power, mountain sleds that we ride and love now as adults. Many families need a sled like the SX Venom to keep the interest of and continue to build the mountain riding skills of their children.
The Final Edition
This year, in June, Yamaha announced that the model year 2025 will be its last year producing snowmobiles. Each 2025 sled sold will have the “1968–2025 Final Edition Yamaha” badge mounted near the fuel tank. This Final Edition badge marks the end of a 58-year era of innovation and industry-leading technology.
2025 SX Venom Engine and Features
The 2025 SX Venom is an easy-to-ride snowmobile, driven by a 397 cc two-stroke engine. The 397 cc engine is a good fit for this sled because it’s lightweight and delivers power in a very linear and controllable manner. Just what you want and need if you are someone learning to ride a mountain snowmobile. This smooth engine package has some features that might surprise you.
Engine Features:
- Computerized Ignition (ECM);
- Three-stage Exhaust Power Valve;
- Batteryless Fuel Injection;
- Electronic Oil-injection;
- Electric start;
- Tuned Exhaust;
- Exhaust Pipe Temperature Sensor (EPTS);

Keeping the Weight Down
The 2025 SX Venom is built on an aluminum chassis. It was designed to keep the weight down while still maintaining the durability that Yamaha is known for. The SX Venom is driven by the CVTech Trail Bloc drive clutch and Invance driven clutch system. This clutch design assists with low temperature operation, and creates a wider ratio transmission through the secondary pulley to maximize the compact 397 cc engine.
2025 SX Venom Track and Rear Skid.
The 2025 SX Venom comes with a 15-inch-wide and 146-inch-long track with 2-inch lug depth for extra traction off-trail. It also has a 12-inch travel rear suspension with the single-rail design. This single-rail design helps the sled initiate a turn and feel light when riding. The 10.5-gallon fuel tank and the very efficient 397 cc EFI engine enable this sled to go a long way on a tank of fuel.
Controls and Gauge
The cockpit on the 2025 SX Venom has a simple and clean design with very few frills. It does include, however, all the basic controls a newer rider needs. It has handlebar and throttle lever warmers as well as a push-button reverse with an audible back-up beeper. Also, it has an easy-to-use turnkey electric starter and even a tether for safety. It wasn’t that many years ago that even the biggest of mountain sleds didn’t come standard with a tether. The 2025 SX Venom also comes with a compact digital gauge that shows the rider speed, RPM, fuel level and hours. There are also indicator lights to warn against oil or engine temperature issues.
