Polaris 800 Engine Specs

Polaris manufactures a variety of off- and on-road vehicles including golf carts, ATVs, snowmobiles and motorcycles. It is one of four big factory racing teams that participate in the World PowerSports Asoociation (WPSA) Snowcross circuit. Polaris gives the 800 designation to several of its most powerful and capable vehicles in its snowmobile and all-terrain vehicle (ATV) lineup. The exact specifications and utility of the engine vary between models.

  1. 800 Pro-RMK 163

    • As with all the Polaris 800 series snowmobiles, the Pro-RMK 163 has a two-stroke, 795 cc engine with a 85 mm by 70 mm stroke and bore. It has a digital capacitor discharge ignition (CDI), a single pipe virtual exhaust system (VES), and "Cleanfire" injection. Cleanfire is an electronic fuel injection (EFI) system that has four injectors instead of the normal two, and burns cleaner than standard EFIs. With an overall design philosophy of being lightweight yet durable, it utilizes the RMK Lightweight Cyclone brake type.

    800 Switchback Assault 144

    • The Switchback Assault 144 has the same engine specs as the Pro-RMK with the exception of the disc brake type. The Switchback utilizes the Phantom hydraulic brake type, and is marketed as a cross between the RMK and Rush series, capable of both on- and off-road driving.

    800 Rush Pro-R

    • The fuel injection system on the Rush Pro-R snowmobile compensates for elevation change to ensure easy starts and crisp performance. It has a slightly smaller gas tank that holds 11 gallons, as opposed to the 11.5 gallons of the Switchback Assualt and Pro-RMK.

    Ranger 6x6 800

    • The Ranger 6x6 800 is similar to the Sportsman Big Boss in that it had six-wheel drive, and similar to the Ranger XP 800 in aesthetic design. The engine is still 760 cc, but the engine is tuned to tow heavy loads. It has 10 less horsepower than the Ranger XP at 40 horsepower, but double the towing payload/capacity at 2,000 lbs.

    Sportsman 800

    • The Polaris Sportsman 800 is the brand's best-selling automatic 4x4. The all-wheel drive system automatically engages all wheels when more traction is needed, and reverts to two-wheel drive when it's not. It has an engine braking system that allows you to easily crawl down steep hills at a slow pace. According to atvsforcheap.net, "the Sportsman 800 has a dual exhaust system that gives the 800 twin engine more torque output and power."

    Ranger XP 800 EPS

    • The Ranger XP is an ATV with a four-stroke twin cylinder engine rated at 50 horsepower with a 55 mph top speed. It has a 760 cc high output (HO) displacement, electronic fuel injection, and a liquid cooling system.

    Sportsman Big Boss 6x6 800

    • According to polarisindustries.com, the "Sportsman Big Boss 6x6 800 ATV is our Hardest Working 6x6 ATV ever." It has a 760 cc twin-cylinder EFI engine that powers a true six-wheel drive powertrain.
