Polaris 800 Pro RMK 155 VS Ski-Doo Summit X154 800R E-TEC – COMPARISON

Polaris RMK 800 is a universal snowmobile from a well-known brand, in demand in Russia and abroad. The model under consideration received high performance qualities, which were confirmed by factory testers, as well as ordinary users. The owners of this snowmobile are family people, as well as athletes, fishermen and hunters. Based on this, we can conclude that the car attracts not only its appearance, but also its driving characteristics. This snowmobile is the most popular on the Russian market, among other Polaris models.

Polaris RMK 800 is a multi-purpose mountain-class snowmobile designed to perform professional tasks. Thus, before us is not just a car for recreation, but also for work needs. The scope of application of the Polaris RMK 800 snowmobile is extensive and varied. The equipment is capable of towing sleds and loads, as it has a high carrying capacity. The machine can be used in mountain conditions, on a specially prepared track with compacted snow, as well as on an icy road. This model is equipped with an engine adapted to high loads. The motor does not experience problems associated with overheating or hypothermia. The power unit makes it possible to quickly reach maximum speed if it is necessary to overcome a certain section of the road within the allotted time. We must admit that this is one of the fastest snowmobiles in its price category.

The manufacturer took care of the high driving qualities of the snowmobile, and specially for this purpose equipped it with an extended Competition track, which features high lugs. This made it possible to increase geometric cross-country ability on slippery ice, as well as loose snow-covered surfaces. The rugged frame construction and proprietary Pro-Ride suspension ensure smooth passage of obstacles with a high level of comfort. In addition, the suspension and frame were significantly lighter thanks to the use of carbon materials. The QuickDrive drive system, which uses aluminum side steps, has also been significantly lightened. The rear suspension includes coil springs, which are necessary when driving in deep snow. In general, all of the above components significantly increased the vehicle’s maneuverability and improved comfort.

If necessary, you can order a special configuration designed for driving on special roads - for example, with jumps. For such conditions, a unique suspension has been developed that is resistant to jumps and other extreme conditions. Among the features of this suspension (it is installed at the front) is the absence of a stabilizer, as well as the ability to adjust the stiffness to adapt the car to certain road conditions. So, especially for this purpose, the suspension is equipped with adjustable Walker Evans shock absorbers. Among other features, we note a durable caterpillar track with special rigidity parameters. With such a caterpillar there should be no problems when moving on snowy and icy surfaces. As a result, we have a car with excellent driving characteristics, high strength and stability. At the same time, we will add simple and understandable controllability, which does not require professional skills. From this point of view, the machine can be recommended to novice users. We note the ability of the Polaris RMK 800 snowmobile to quickly overcome steep turns, as well as actively avoid obstacles - for example, stones or trees. It was possible to achieve such driving qualities not only with the help of outstanding chassis parameters, but also by reducing the weight of the structure, which uses lightweight composite materials.

Design and equipment

The Pro-Ride frame and suspension are lightweight to make the snow machine faster and more maneuverable. Carbon inserts protect internal parts in the event of a collision. The basic package includes the following elements:

  • Electric starter;
  • Reverse gear;
  • Heated steering wheel grips and throttle trigger;
  • Windshield;
  • Passenger backrest;
  • Rear towbar;
  • Speedometer;
  • Odometer;
  • Front reinforced bumper;
  • Rear reinforced bumper;

The Polaris 800 RMK is simple and easy to control. The equipment is able to maintain balance even when taking sharp turns. The side steps are made of aluminum. They are wide and your feet won't slip off them.

Engine

The Polaris RMK 800 snowmobile is equipped with a gasoline power unit from the environmentally friendly Liberty family of Polaris' own production. The engine has a compact two-cylinder layout with a displacement of 800 cc. cm. Each cylinder is 85 mm long and the piston stroke is 70 mm. The engine develops 154 horsepower, which is one of the best figures in its class. The unit is equipped with liquid cooling with a restart function. The multifunctional cooling system provides the ability to work not only in frosty, but also in relatively warm seasons - for example, at temperatures above zero degrees. The motor will not experience overheating. For uninterrupted operation of the engine in frosty conditions, an electric starter and a pre-heater help well, without which it is hardly possible to do at minus 40 degrees and below. As practice and factory tests show, the average gasoline consumption of a Liberty family engine is 16-17 liters per 100 km.

But there is a configuration designed for performing various jumps and the like, that is, for extreme driving. In this case, the snowmobile is equipped with a powerful front suspension, which does not have a stabilizer. This suspension allows you to adjust the base of the skis, which allows you to prepare the machine for certain operating conditions. There are also Walker Evans® adjustable shock absorbers. The caterpillar belt has lugs with increased rigidity, thanks to which the machine can be used not only on snow surfaces, but also on ice. All this together gives the snowmobile quite high strength, stability and easy control in various situations.

The second modification, also known as Polaris 800 PRO-RMK 155, is a version exclusively designed for extreme operating conditions. Among its class, this model occupies a leading position; this mountain device will allow you to get an unforgettable experience from traveling along the most difficult routes.

As for the snowmobile's handling, the Polaris 800 PRO-RMK 155 is quite simple and manageable. The equipment is able to maintain balance even when taking very steep turns. By its structure, this modified version has high reliability of most parts and assemblies. The manufacturer managed to significantly lighten the model without losing strength and rigidity. As in the previous modification, this one has a 795 cc power plant, which allows you to overcome various obstacles that arise when traveling long distances. The model can be used both in the mountains and on ice.

Price

The average cost of a Polaris 800 snowmobile on the Russian market is 1 million 200 thousand rubles. The price is for a new car for the basic configuration. As for a used snowmobile, its final cost depends on the technical condition, mileage and year of manufacture. Thus, the estimated price of the RMK 800 model is 850 thousand - 1.1 million rubles. The manufacturer provides a warranty period of 12 months for a new snowmobile. In the event of problems occurring within the specified period, the owner has the right to receive a free service from the service to eliminate the problem.

Snowmobile Polaris 800 RMK Assault 155

Another modification is the RMK Assault 155, a station wagon for little money. The snowmobile is ideal for “rides”, and is also capable of performing everyday tasks, such as towing cargo. The universal characteristics of the model allow you to ride on mountain trails and prepared tracks with ice. The engine capacity of 795 cc remains the same, but lightweight performance and other features make the snowmobile the fastest among other Polaris 800 modifications.

The “machine” showed itself ideally in mountainous areas; the tracks on Polaris snowmobiles were created in the Competition style - they have a good length and the presence of lugs. The latter provide a good and confident ride on slippery surfaces. Among other innovations, it is worth highlighting the lightweight QuickDrive drive system, the presence of carbon inserts in the suspension, as well as aluminum side steps. If you operate the Polaris 800 in heavy snow, the coil spring rear suspension helps ensure a comfortable ride.

Reviews

  • Daniil, Magnitogorsk. Not a bad snowmobile. Only very expensive. At the end of 2021, the car cost me 1.2 million rubles. This model impressed me, and I primarily noted its stylish design, excellent handling and powerful engine. The RMK 800 model is capable of driving on compacted snow and icy roads, as well as on loose snowy terrain. In short, this snowmobile rushes like a tank and does not cause any problems. I've been using it for about 4 months. Sharp steering and wide tracks contribute to excellent maneuverability and directional stability. I often go hunting and fishing with my men; by the way, they also have imported snowmobiles. In terms of handling, my car is on par with the Japanese Yamaha. I hope that Polaris will continue to please me with its reliability. I only fill up with oil and fuel. By the way, the snowmobile officially supports 92nd gasoline.
  • Boris, Nizhny Novgorod region. A good car for every day. I would like to note the high-quality finishing materials that immediately catch the eye, as well as the perfectly fitted details. In general, the build quality is excellent. This is the first impression. In two months I drove more than 1000 kilometers - I really liked the car, it doesn’t break down at all. I am sure that this will continue to happen. At speeds above 80 km/h, fuel consumption increases, but this is quite natural, and it’s a sin to complain. The windshield seemed a little low to me - because of this, the cold wind hits me directly in the face, which, to put it mildly, is not very pleasant. This seems like a small thing, but at the same time it is a serious drawback for such an expensive snowmobile. I had to buy a helmet, and now everything is fine.
  • Garik, Yaroslavl region. A too expensive snowmobile, which I still decided to buy. It has a power of more than 150 hp. s., and from this a certain confidence and pride in the car appears. But these are only the first sensations, since in practice there is nothing like this. Of course, the engine has good dynamics, accelerates quickly, but without spark. This is absolutely not a sports snowmobile - believe me, I have ridden real racing snowmobiles, which the RMK 800 model is no match for. A heavy but overly sensitive steering wheel, sharp but somewhat nervous handling, a stiff suspension and a low windshield are all design flaws that you cannot fix on your own. Fuel consumption is too high for a home snowmobile, especially at maximum speeds. The model has never broken down in two months – well, at least that’s a good thing, but still the price is very high. I cannot recommend this model for purchase, as there are serious shortcomings in terms of controllability and efficiency.

Polaris 800 DRAGON RMK review

The Polaris RMK 800 snowmobile is the ideal choice for the Russian user, comfortable, soft, high quality. For quite decent money, the buyer will receive a lightweight seat, a 12-inch diameter windshield with a transparent base, and a digital display with many functions is now installed as a dashboard. The basic equipment will already please every buyer, but as options you can order a 12V socket, mirrors, a rear trunk and a towing device. In the basic version you can find such elements as an electric starter, handle and lever heaters.

The new product has already received a lot of positive reviews, in particular, they note that the weight has been reduced by 11.3 kg. This is possible thanks to the use of lighter materials and alloys in the base. A Series 5 track is installed, designed specifically for mountain travel. Together with it, an excellent rear suspension helps to conveniently distribute the weight of the snowmobile and improve off-road performance. Tests were carried out before using the Gripper RMK skis, so the device has proven itself ideal on climbs and on difficult terrain. Branded shock absorbers from Walker Evans are adjustable, very high quality and are distinguished by the presence of an aluminum body and have heat-treated valves. Synthetic oil is poured into the shock absorber. This is an ideal solution for suspension operation in the coldest weather, the manufacturer has provided everything.

Evolution

By and large, there are no fundamental changes in the new RMK. No new suspensions, no turbocharged engines, no conceptually revolutionary platforms. But the reduction in the weight of the snowmobile without loss of structural rigidity compensates for the lower engine power compared to its competitors and the lack of striking technical innovations.

Some will say that the difference in weight is too insignificant for a vehicle with one hundred and fifty or more horses under a plastic hood. So, believe me, there is a difference, and quite noticeable!

In the right hands, RMK Pro works wonders. Like a sharpened blade, it easily and quickly cuts through sheets of virgin snow, storms mountain slopes in a controlled and predictable manner, and effortlessly accelerates to three-digit values ​​on the speedometer. So, despite the lack of fundamental changes to the RMK platform, the war in the mountains continues. And I wouldn’t speak with confidence, for example, about the undoubted advantage of the new BRP Summit over the RMK Pro.

The winner in this confrontation will be revealed by an analysis of sales levels at the end of the 2013 winter season.
