We at PowerSportsGuide have compiled the HP ratings of some of the most popular Polaris sleds into one chart!

How Much Horsepower Does a Polaris Snowmobile Have?

How Much HP Does a 120cc Polaris Snowmobile Have?

The tiny Polaris Indy 120 is engineered for children 6 years old and up. This lovely mini-sled is powered by a 121cc, 4-stroke single that features free-air cooling and a Mikuni BV-18 carb.

Although the official engine power is not listed, you can expect the performance of a stock Indy 120 to be in the ballpark of 4-8 HP depending on the year.

The engine features a basic speed governor, which restricts the speed of the machine to 8 mph. Bypassing this governor allows the sled to reach speeds of up to 13-15 mph.

How Much HP Does a 250cc Polaris Snowmobile Have?

It’s a lesser-known fact that certain vintage Polaris snowmobiles used 250cc engines in the ‘70s and ‘80s. These 2-stroke, fan-cooled engines generated about 18 HP.

One of the most well-known 250cc Polaris snowmobile engines was the Fuji 244cc. This 2-stroke, fan-cooled twin was rated at 18 HP and was used in several models including the 1988 Polaris Star Blue 250 and the Polaris TC 250.

The latter was a small compact sled designed to fit in a standard station wagon. It was available with two engine options, the Fuji 175cc single (10 HP) as well as the Fuji 244cc twin (18 HP).

How Much HP Does a Polaris 400 Snowmobile Have?

The horsepower ratings of vintage 350-400cc Polaris snowmobiles start at 35 HP and range up to 65 HP.

For example, the fan-cooled, 2-stroke, Fuji 339cc twin engine was used in many models including various Indy models like the Sport, GT, and Touring.

Later this engine configuration was carried over for many newer sleds including the Classic 340 and the LX 340.

For buyers looking for more engine power, Polaris marketed many great sleds with more powerful, 400cc engines.

The most popular models in this breed were arguably the Indy 400s powered by a liquid-cooled, 398cc twin engine rated at 62 HP. This power mill was much more powerful and faster than its 440 fanner counterparts.

Some popular sleds in this category were as follows:

  • 2004 Polaris Classic 340: 36 HP
  • 2007 Polaris LX 340: 36 HP
  • 1988-1992 Indy 400: 62 HP
  • 1991 Polaris XC 400: 62 HP

How Much HP Does a Polaris 440 Snowmobile Have?

Polaris 440 snowmobiles were marketed with both fan-cooled and liquid-cooled engine options. The 2-stroke, fan-cooled 440cc Polaris twin engine cranked out about 45-55 HP while their more advanced liquid-cooled counterparts offered 80-105 HP depending on the year.

In the early ‘90s, the liquid-cooled 440 Polaris sleds provided about 80 HP, but everything changed in 1997 when the manufacturer introduced its VES (Variable Exhaust System), which added about 6-10 HP to every engine.

By the end of the ’90, the majority of stock 440 Sno-Cross sleds could reach a whopping 95-105 HP!

Some of the best Polaris 440 snowmobiles were as follows:

  • 440 Fuji fanners: about 45-55 HP
  • 1995 Polaris XCR 440: 87 HP
  • 1997 Polaris XCR 440: 98 HP
  • 2005 Polaris 440 IQ Sno Pro: 105 HP

How Much HP Does a Polaris 500 Snowmobile Have?

The engine power of Polaris 500 snowmobiles ranges from 50 up to 110 HP.

Polaris 500 engines were available with triple and twin configurations depending on the model. However, the latter was more common in the domestic market.

The lesser-known Polaris 500 triple made its debut in the early ‘70s. One of the first commercially available models was the 1972 Polaris TX 500 LTD, powered by a free-air cooled, 502cc Fuji triple engine.

The features of this sled were carried over for the 1973 TX 500, which produced about 50 HP at 6500 RPM.

Later, a liquid-cooled configuration of this engine appeared in some other models like the 1979 Centurion, and became the predecessor of Polaris 600 and 650 triple engines.

The deservedly popular Indy 500 was also available with various twin-engine options, including the fan-cooled 488 (56 HP), 500 EFI, or the liquid-cooled and carbed 500. The latter was used in the Indy Classic.

The engine power of these models ranges from 56 HP up to 80 HP.

It’s safe to say that the Indy 500 was one of the most popular snowmobiles in history, as it was marketed for 18 years from 1988 through 2006.

Besides the Indy 500, some other well-known Polaris 500 sleds were as follows:

  • 1973 Polaris TX 500: 50 HP
  • 1979 Polaris Centurion: 100 HP
  • 1991 Polaris Indy 500: 72 HP
  • 1999 Polaris Indy 500: 78 HP
  • 2007 Polaris 500 XC SP 500: 105 HP

How Much HP Does a 550cc Polaris Snowmobile Have?

Interestingly, Polaris 550 snowmobiles only produce about 55-60 HP, since they typically utilize fan-cooled, 550cc twin engines.

You can still find 550 models in the latest Polaris lineup, like the Indy 550 and Indy Evo 550.

Other vintage Polaris sleds in this category include:

  • 2004 Polaris Super Sport 550: 60 HP
  • 2006 Polaris Edge Touring 550: 60 HP
  • 2007 Polaris LX 550: 60 HP

  • 2021 Polaris Indy Evo 550: 55 HP

How Much HP Does a Polaris 600 Snowmobile Have?

You can expect the performance of a Polaris 600 snowmobile to be in the ballpark of 88-125 HP.

Some of the early sleds in this class were the XC, XCR, as well as XLT (Xtra Lite Triple) models.

The majority of these produced 88-100 HP except for the 1996-1998 XCR 600. Thanks to its factory-installed “triple-piped” exhaust configuration, this machine delivered a whopping 116 HP.

A lot of later 600 models utilized the popular and reliable Polaris Liberty 600 engine, which debuted in the late ‘90s. This liquid-cooled power source produced about 115-125 HP depending on the year.

In the mid-2000s, the manufacturer offered two different 600 engine options. The carbureted Polaris 600 HO was rated at 120 HP while the fuel-injected 600 HO CFI (CleanFire Injection) delivered 125 HP.

Some of the best Polaris 600 sleds are as follows:

  • 1993-94 Polaris XLT and XLT-SP: 88 HP

  • 2014 Polaris 600 Pro-RMK 600: 125 HP

How Much HP Does a Polaris 650 Snowmobile Have?

Polaris introduced its 2-stroke Patriot 650 twin-engine in 2020, which generates about 130-135 HP.

This power source is considered a smaller sibling of the Patriot 850 since these engines share the same block and many other features.

The Patriot 650 engine is used in many great Polaris sleds, including:

  • 2022 Polaris Indy XC 650: 135 HP
  • 2021 Polaris Indy VR1 650: 135 HP
  • 2022 Polaris Indy XCR 650: 135 HP

How Much HP Does a Polaris 700 Snowmobile Have?

Generally speaking, Polaris 700 snowmobiles produce about 120-140 HP depending on their engine configuration.

The legendary Liberty 700 engine was produced in two different versions.

The pre-’97 units are commonly known as “non-VES” Liberty engines since they lacked the exhaust power valves. These early Liberty 700 engines produced about 118-120 HP while their more advanced successors with VES valves had a remarkable 128-130 HP.

By 2007, Polaris had introduced its new Liberty 700 engine in the Dragon. This liquid-cooled, 700cc twin produced a remarkable 140 HP.

These 700cc Polaris snowmobile engines already had a good reputation for their excellent reliability and durability.

For example, you can find these engines in the following models:

  • 2003 Polaris 700 Pro X: 120 HP
  • 2002 Polaris Edge X 700: 130 HP
  • 2004 Polaris 700 Switchback 130 HP
  • 2004 Polaris 700 XC 130 HP
  • 2001-05 Polaris Edge XC 700: 130 HP

  • 2003 Polaris SKS 700: 130 HP
  • 2004 Switchback 700: 130 HP
  • 2007 Polaris IQ Dragon 700: 140 HP
  • 2009 Polaris RMK 700: 140 HP

How Much HP Does a Polaris 750 Snowmobile Have?

Polaris offered several 750cc snowmobile models over the years that were typically rated at 80-140 HP.

The first 750cc Polaris snowmobile engine was the liquid-cooled, 2-stroke Fuji 744cc triple that debuted in the 1993 Polaris Indy Storm.

This lively sled was the first stock triple-piped Polaris snowmobile, meaning that it featured three tuned pipes as well as reed valve induction. Thanks to these advanced features, the Fuji 744 cranked out about 137 HP.

The main idea behind this new engine was to keep up with the increasing performance of Yamaha’s Vmax4 and Arctic Cat’s Thundercats.

The 2-stroke Polaris 750 engines made a comeback in 2006 with the introduction of the “Fusion 700” engine. Contrary to its name, this engine was a 755cc 2-stroke twin rated at 138 HP.

It shared its block with the Fusion 900 (866cc) engine but featured smaller cylinders.

This engine was nestled in many 2006 Polaris sleds including the RMK 700 (755), and the Edge Touring 2-up 700 (755).

Unfortunately, this power mill had a bad reputation for its frequent overheating and vibrating issues. What’s more, due to its large block it was quite heavy as well.

Therefore, the Fusion 700 never became popular, so Polaris dropped it after only one year of production.

Besides their 2-stroke counterparts, 4-stroke Polaris 750 snowmobile engines also appeared in the 2000s.

The all-new parallel-twin 749cc power source was manufactured in Germany by Weber. As reported by, this unit was originally engineered as a microcar engine.

Polaris offered this engine in two variations, the 2006 Polaris FS Classic came with a naturally-aspirated, 80 HP engine configuration.

In contrast, the 2006 FST Switchback and FST Classic housed a turbocharged engine option rated at 140 HP. The latter was positioned as a luxury trail sled equipped with several convenience features.

The new 4-stroke Polaris 750 engine instantly became popular among riders, due to its low emissions and smooth, fuel-efficient operation.

Some of the best Polaris 750 sleds were as follows:

  • 1993 Polaris Indy Storm 750: 137 HP
  • 2006 Polaris RMK 700 (755cc): 138 HP
  • 2006 Polaris Edge Touring 2-UP: 138 HP
  • 2006 Polaris Classic FS IQ Touring 750: 80 HP
  • 2006 Polaris Classic FST 750: 140 HP
  • 2007 Polaris FST IQ LX 750: 140 HP
  • 2009 Polaris FST Switchback 750: 140 HP

How Much HP Does an 800cc Polaris Snowmobile Have?

Polaris has been offering snowmobiles with 800cc since the ‘90s. Whereas the vintage Polaris 800 sleds produced about 110-150+ HP, you can expect 150-160+ HP on their modern brothers.

The early Polaris 800 engines proved to be less reliable than their small-bore siblings, as they suffered from various factory defects.

Later many of these bugs were worked out, and the VES exhaust valves pushed the performance of these power mills into a range of 130-150 HP.

In the late ‘90s and early ‘00s, Polaris 800 twin engines were capable of 120-140 HP, while the triples could even reach a whopping 150 HP.

The last 2-stroke Polaris 800 triple engine was used in the sports XCR 800, manufactured from 1999 to 2003.

A lesser-known 4-stroke Polaris 800cc snowmobile was the Polaris Frontier Classic 700. Contrary to its name, this sled was powered by a 784cc, 4-stroke engine rated at 48 HP.

This horizontal in-line twin had a similar design as that of Polaris ATV engines, but it came with electronic fuel injection.

Polaris’ new 800cc engine, the Liberty 800 was revealed in 2008. Although the claimed power of this engine was 154 HP, it could only reach about 145+ HP on the dyno.

As you can imagine, it led to many misunderstandings and unpleasant moments for the manufacturer.

The Liberty 800 was redesigned in 2014 when it got a semi-direct injection (SDI) and was rebranded as the Liberty 800 Cleanfire H.O.

By the late 2010s, this power source saw some updates, and its performance was increased up to 160+ HP.

As a reference, here is a list of some of the best Polaris 800 snowmobiles:

  • 2004 Polaris Frontier Classic 700: 48 HP

The first Polaris 900 snowmobile engine was the Liberty 900. This all-new power source was introduced in 2004 for the 50th Anniversary Celebration of Polaris snowmobiles.

The Liberty 900 engine was revealed in the all-new Polaris Fusion sled. This horizontal in-line, 2-stroke, liquid-cooled, 866cc twin cranked out about 150 HP and was designed with the stricter environmental restrictions in mind.

Polaris 900 snowmobiles have now made a comeback in 2023 with the all-new Patriot 9R engine. Although Polaris doesn’t advertise the engine power of this liquid-cooled, 2-stroke, 899cc twin, it’s claimed to produce 12 percent more torque and 7 percent more HP than the Patriot 850, Snowest reports.

Since the naturally-aspirated 850 produces about 186 HP, we can expect the engine power of the Patriot 9R to be in the ballpark of 175-180 HP.

As a reference, here are some popular Polaris sleds with 900 engines:
