Ski-Doos can go as fast as 55-128 mph depending on their engine and design. The slowest Ski-Doos are the utility models like the Skandic, Tundra, and Expedition. The top speed of these models ranges from 55 mph up to 70 mph. In contrast, the fastest Ski-Doo can hit an amazing 128 mph! Regarding the “average” Ski-Doo models, it’s safe to say that their top speeds typically fall into the 80-110 mph range.

Keep in mind that the top speed of a Ski-Doo depends on several factors, many of which may vary from one ride to the next. The most important ones are as follows:
- The model year
- The sled’s condition
- Settings and modifications
- Type of cooling system (fan-cooled vs. liquid-cooled)
- Type of fuel and oil
- Track dimensions / Studs
- Gross weight
- Snow conditions
- Terrain
- Altitude
- Ambient temperature
- Humidity
- Wind
As you can see, many factors affect the available speed on a Ski-Doo. That’s why the numbers in this article should be considered as approximate values. However, these are pretty average numbers that most riders can typically reach without any issues.
Also, it’s good to know that these top speed numbers were read from speedometers, which usually show 5-10% higher speeds than the actual speed. If you want to check the actual speed of a Ski-Doo you should use radar or GPS.
Let’s move on and take a closer look at the performance of Ski-Doo snowmobiles by category!
The Slowest Ski-Doo
The slowest Ski-Doo was arguably the Ski-Doo Alpine, which was manufactured in the late ‘70s. This model also carries the “world’s slowest snowmobile” title as well! The Alpine was designed for workmen who appreciated the machine’s reliability and durability.
It featured a massive steel frame and 15-inch twin tracks. It was powered with a 436cc, 2-stroke, 2-cylinder Rotax engine, which was equipped with a mechanical reverse as well.
Thanks to these features, it was able to haul heavy loads without any issues.
300-500cc Ski-Doo Models
When it comes to vintage Ski-Doo models, most of them were manufactured with 300-500cc engines. The most commonly used power sources were the Rotax 300, 377, 380, 440, 470, 500, and 583 engines. Surprisingly, many of these vintage sleds are still running on the trails!
The 377-380 Rotax engine typically offered 45-65 mph, while the Ski-Doos with 440-500cc engines can reach a top speed of 70-85 mph.
Here are some top speed numbers of popular vintage Ski-Doo models:
- Ski-Doo Freestyle 300 top speed: 40-45 mph
- Ski-Doo Safari 377 (Fan) top speed: 45-50 mph
- Ski-Doo Formula S 380 top speed: 55-65 mph
- Ski-Doo MXZ 380 top speed: 55-65 mph
- Ski-Doo GSX 380 top speed: 55-65 mph
- Ski-Doo MXZ 440 top speed: 70-80 mph (liquid-cooled) 60-70 mph (fan-cooled)
- Ski-Doo MX 470 top speed: 75-80 mph
- Ski-Doo Formula Z 500 top speed: 80-85 mph
- Ski-Doo MXZ 500 top speed: 75-85 mph
550cc Ski-Doos
Ski-Doos with the 550cc 2-stroke Rotax engine are still available off the shelf. The top speed of these Ski-Doo 550 snowmobiles ranges from 65 mph up to 90 mph. Some popular models are the MXZ 550 and the Skandic 550, which is a utility sled with moderate top speed.
- Ski-Doo MXZ 550f top speed: 80-90 mph
- Ski-Doo Skandic 550 top speed: 65-75 mph
- Ski-Doo Renegade 550f top speed: 65-75 mph

- Ski-Doo Grand Touring 583 top speed 85-90 mph
- Ski-Doo Formula Deluxe 583 top speed: 90-95 mph
How Fast Does a Ski-Doo 600 go?
Ski-Doo 600 snowmobiles can go as fast as 55-110 mph, thanks to the 600R E-TEC engine (125 HP). The slowest models in this category are the utility sleds again with a top speed of 55-95 mph. However, these sleds are definitely not designed for trail racing! In contrast, the fastest Ski-Doo 600 models can reach a remarkable 100-110 mph under ideal conditions.
The most popular Ski-Doo 600 models are as follows:
- Ski-Doo Tundra 600 top speed: 55-60 mph

How Fast Does a Ski-Doo 800 Go?
Ski-Doo 800 sleds can go as fast as 85-115 mph. All of these models are powered with the 800cc, 2-stroke 800R E-TEC Rotax engines. Mountain Ski-Doos like the Summit offer slightly lower top speed, but it’s not a big issue in an off-trail sled. Performance-minded riders can choose from many other 800cc trail Ski-Doos, which can easily hit 105-115 mph!
Here are some popular models in this category:
- Ski-Doo Summit 800 top speed: 85-90 mph
- Ski-Doo XRS 800 top speed: 105-110 mph
- Ski-Doo REV 800 top speed: 105-110 mph
- Ski-Doo MXZ 800 E-TEC top speed: 105-115 mph
Top Speed of Ski-Doo 850 Snowmobiles
The top speed of the 850cc Ski-Doos can reach the amazing 100-130-mph range. That’s why these sleds are considered to be the flagship models in Ski-Doo’s fleet! They are powered with the 850cc, 2-stroke, E-TEC Rotax engine, which puts out no less than 165 HP.
- Ski-Doo Freeride 850 top speed: 85-95 mph
- Ski-Doo 850 Renegade top speed: 105 – 115 mph
- Ski-Doo Backcountry X 850 top speed: 100-110 mph
- Ski-Doo Summit 850 top speed: 90-100 mph
- Ski-Doo MXZ X 850 E-TEC top speed: 120-130 mph
How Fast Does a 900 ACE Go?
The 900 ACE is also a popular 4-stroke power source of some touring and utility Ski-Doo models. It features 3 cylinders and produces 95 HP. (On pre-2019 sleds it was only 90 HP.) Ski-Doos powered with the 900 ACE can typically reach the top speed of 80-90 mph.
If you are looking for Ski-Doos with this engine option, you should take a look at the Renegade or the Grant Touring 900.
- Ski-Doo Renegade 900 ACE top speed: 80-90 mph
- Ski-Doo Grand Touring 900 ACE top speed: 80-90 mph
How Fast Does a Ski-Doo 1200 Go?
The top speed of Ski-Doo 1200 snowmobiles is about 95-110 mph. These models are powered with the 1170cc, 3-cylinder, 4-stroke Rotax engine, which is currently the biggest snowmobile engine in the industry! You can find this power source in the Renegade 1200 or the MXZ 1200.
- Ski-Doo Renegade 1200 top speed: 95-105 mph
- Ski-Doo MXZ 1200 top speed: 100-110 mph
What is the Fastest Ski-Doo?
The fastest Ski-Doo is arguably the MXZ X 850, with a 128 mph (recorded) top speed! This high-performance Ski-Doo comes with the 850 E-TEC Rotax engine and weighs only 471 pounds. If you want to learn more about this sled, don’t miss this informative review:
Conclusion
Ski-Doo top speed numbers vary widely depending on the model. Even the slowest models can hit the 60-70 mph range, while the fastest Ski-Doos can go as fast as 100-130 mph!
When it comes to the performance of Ski-Doo engines it’s safe to say that they depend on many factors, which are as follows:
- The higher the displacement the higher top speed you can expect from the sled.
- A 2-stroke engine puts out more horsepower than a 4-stroke engine (with the same displacement).
- Turbocharged Ski-Doo engines offer significantly better performance compared to their naturally-aspirated counterparts.
- It’s good to know that new Ski-Doo models come exclusively with fuel injection systems. This means carbureted Ski-Doo engines are not manufactured anymore! The fuel injection system gets the most out of 2-stroke Ski-Doo engines, and also helps keep the emissions low.
This is our short review of the Ski-Doo top speed numbers and engines. We hope you find it useful!
