128 miles per hour
The Ski-Doo MXZ X 850 has a recorded top speed of 128 miles per hour, while the Polaris Switchback Pro-S 800 caps out at 105 mph, and the Arctic Cat ZR 6000 EL Tigre is a bit slower at 88 mph. The Polaris Assault 800 tops off at 112 mph, and Ski-Doo 850 has a top speed of 118 mph.

HHolding the throttle to the bars for about a half mile we recorded 154 km/hour on the Ski-Doo speedometer. For our non-metric buds that translates to 96-mph. Even if you account for 10-percent speedometer error (very common), that still becomes about 86-87 mph.

Ski-Doo MXZ snowmobiles are specifically designed to be the ultimate performance sleds for the trail. They offer instantly responsive, motocross-like handling with exceptional agility. Sporting the latest in snowmobile suspension innovations, MXZ sleds deliver precise cornering, and superior big-bump capability.

1. ZR 9000 Thundercat 137 ARS, 2021 – ARCTIC CAT. Yamaha SRX LE’s claim as the fastest production snowmobile has been disputed by the ZR 9000 Thundercat. In fact, both machines share more similarities than differences.

The REV platform changed the way snowmobilers ride today putting them in a forward leaning position and bringing the center of gravity closer to the middle of the sled. This allowed riders to lean and control the machine on trails and through deep snow with much more ease adding to the overall experience.

2-stroke – 4-stroke is great for an on-trail sled. It’s a more expensive engine up-front but requires less maintenance and will last longer. A 2-stroke engine consumes oil but is more affordable, snappier, and weighs considerably less than a 4-stroke. However, the 2-stroke will require a bit more maintenance.

One of the most important factors to consider when buying a used snowmobile is the state of its engine. A general rule for snowmobile engines is that the higher the performance (aka, turbocharged) of your engine, the shorter the lifespan. On average, snowmobile engines can last between 5,000 and 20,000+ miles.

Snowmobile speed can range from 80 mph to 200 mph, depending on many factors. Beginner sleds are usually slower, while racing snowmobiles are the fastest. Most modern snowmobiles today are high-performance, and can reach speeds of 150 mph and more.
