What is the Fastest Production Snowmobile?

Two snowmobiles are battling it out today for the title of the fiercest and fastest snowmobile on the planet. Equipped with turbocharged 998cc engines, both are powerhouses capable of generating up to 200 horsepower.

So prepare yourself to meet the two contenders for the fastest production snowmobile ever:


The SRX LE has consistently retained the title of the fastest snowmobile on the planet for three years in a row. Spotting the iconic Yamaha sporty blue look, it continues to crush the competition on appearances alone.

On subsequent yearly updates, the engine on the SRX LE models does not undergo much change. Most improvement efforts are focused on the track and suspension, which according to users, leads to remarkable performance differences.

For instance, on the SRX LE 2024, Yamaha revamped its ski type from the Turner III to the new Yamaha Styke Single Keel. The rear suspension also received an upgrade to the more capable Dual Shock SR 137.

When it comes to specs, the SRX LE is star-studded. Delivering unmatched top speed and acceleration is the turbo 4-stroke 998cc engine rated in the ultra-performance class. Introduced in 2016, the YSRC Clutch continues to set apart the snowmobile from its competitors. It’s an improvement of the CVT system and comes with a primary clutch and secondary roller clutch.

The chassis features an independent double-wishbone front suspension designed to limit chassis roll and make for more predictable handling. Front shocks still utilize the Fox 1.5 Zero Intelligence quick-switch system that affords riders three different suspension settings. The drop-link style Dual Shock SR 137 rear suspension is both lightweight and makes for a smoother ride.

SRX LE features the Ripsaw I from Camso, though some sellers may include the Ripsaw II track. Both tracks offer excellent traction and durability, thanks to their hard-wearing lugs.

Key Benefits of the Sidewinder SRX LE

Incredible power: The Genesis turbo engine still retains its reputation and respect as the industry’s definition of quality. It features a nickel alloy turbine body capable of withstanding elevated temperatures. Another unique feature of the engine is the intake system composed of three separate throttle bodies to ensure a quick response with almost no lag.

Efficient power delivery: Calibrated for durability and cool operation, the YSRC crutches efficiently transmit the massive amount of torque from the Genesis turbo engine while still minimizing early belt wear.

Easy handling: The lowered ride height keeps the sled stable in tight corners and at higher speeds. Yamaha centralized the mass to make for a well-balanced sled that is fun to throw around in all conditions.

Brand new single keel ski: The newly-designed ski tries to balance light-weight steering effort without sacrificing the precise handling.

Enhanced comfort: For leg comfort and positioning during long rides, Yahama retained the two-piece, tapered tunnel design with running boards equipped with aggressive foothold alterations that keep your boots in place while offering excellent snow removal.

Heated seat:  Riding on the coldest of winter days will be more comfortable thanks to the seat warmers with two settings.

Ergonomic controls:  Much focus was placed on making the throttle and brake levers easy to operate and fully ergonomic.
