The 800 RUSH® PRO-S is for riders who want the ultimate in cornering and handling, and a sled that virtually eliminates stutter bumps. Its powerful, proven 800 H.O. Cleanfire® engine paired with the AXYS® Chassis deliver Rider-Balanced™ Control, Unrivaled Acceleration, and Rider Centric Comfort.
Rider Balanced Control
AXYS® Chassis
The AXYS® chassis features 93% new parts, including a carbon-fiber overstructure and aluminum handlebars on SnowCheck Select or Limited Edition models and an aluminum overstructure on standard models. The chassis structure and design makes it possible to change the rider positioning, centralize vehicle mass, redesign the rear suspension, add more power, remove weight, and evolve the rider’s riding experience. In short, it is the key to delivering rider-balanced control, unrivaled acceleration, and rider-centric comfort.
Rider Balanced Control
Rider Balanced Control gives the rider:
- Flatter cornering without sacrificing the fun factor
- More precise handling in all conditions
- Better control in big bumps AND chatter bumps
How did we get there? Polaris:
- Put the rider in the right location on the sled.
- Centralized vehicle mass.
- Optimized the suspension geometry to better control pitch.
Rider Balanced Positioning
On the AXYS® chassis, the rider is moved forward to a more balanced position. The rider’s hands are moved 4.5” forward, the feet are 2” forward, the knees are 4.5” forward, and the seat is 4.5” forward. In the neutral riding position, the AXYS® platform provides bite for flatter, positive cornering. When the trail gets rough or the rider jumps off into the powder, rider balance enables the rider to move back and make the front end light to climb up on top of the snow or the moguls.
PRO-XC™ Rear Suspension
The completely redesigned geometry of the PRO-XC™ progressive-rate rear suspension is optimized for the best performance and Rider-Balanced Control. Through innovative Polaris engineering and construction, the suspension is both lighter and stronger, featuring:
- Lightweight, forged aluminum rear crank.
- Completely redesigned crank and pivot.
- Front torque arm was moved rearward to control pitch, increase travel, and improve the rail profile.
Active Pitch Control™
The PRO-XC™ suspension delivers Active Pitch Control™ which controls the pitch by suspension geometry and not simply by a high spring rate. This makes the sled less sensitive to adjustment while allowing optimal weight transfer.
Unrivaled Acceleration
Lightweight
When developing the AXYS® platform, Polaris engineers minimized weight throughout the sled without compromising strength. The 800 RUSH PRO-S is more than 30 pounds lighter than the previous chassis and weighs at least 30 lb. less than a competitive trail performance model.
800 Cleanfire® H.O. Engine
Developed in conjunction with the AXYS platform, the proven 800 Cleanfire® H.O. Engine delivers class-leading acceleration. The integrated mounting position optimizes the balance of the chassis. Featuring:
- 3-stage electronically-controlled exhaust valves
- Electronic oil pump
- Thermostat with bypass warms up to operating temperature 40% faster and improves durability
- High-efficiency intake and exhaust
- VForce Reeds
- Lightweight crankshaft
- Throttle body is lighter weight and reduces throttle effort
- Grooved Piston
3-Stage Electronically-Controlled Exhaust Valves
3-stage electronically-controlled exhaust valves provide improved running quality, crisper throttle response, smoother idle and improved fuel economy. The active feedback for the exhaust valve position provides more accurate fueling in transient situations. These exhaust valves also improve combustion stability, leading to improved durability and engine life.
Electronic Oil Pump
Electronic oil pump eliminates power-robbing gear drive – and provides more precise, improved oil delivery for performance and durability as well as a 35% reduction in throttle effort. Requires no adjustments.
High-Efficiency Intake and Exhaust
Porous intake duct material and high-flow exhaust system create a better breathing engine package for more power. The silencer provides reduced sound levels while on the trail. Vforce reeds provide improved performance, throttle response and reed durability.
VForce Reeds
Provide improved performance, throttle response, and reed durability.
Lightweight Crankshaft
Lightweight crankshaft weighs 2.5 lbs less, delivering 25% lower inertia and quicker throttle response and spooling. This provides improved acceleration. Designed and engineered specifically for the 800 Cleanfire® H.O. Engine for increased durability, this same lightweight crankshaft is used in Polaris Race sleds, including during the past 2013-14 and 2014-15 seasons, showing it's proven durability.
800 Cleanfire® H.O. Engine Piston
Grooved piston was designed specifically for the 800 HO Cleanfire® Engine to increase durability and engine life.

Interactive Digital Display
Another industry first for Polaris - the most advanced instrumentation in snowmobiling. This 4.3" high resolution, full color, LCD digital display provides a rider with information including:
- Sled performance: Speedometer, tachometer, dual tripmeters, average speed, max speed, engine/trip hours & odometer
- Sled operating conditions: Coolant temperature, diagnostics & maintenance warnings
- Riding conditions: Air temperature, time of day in 12 or 24-hour clock format

- This gauge comes as an option on some SnowCheck models, and is available as an accessory option
Left-Hand Controls
The left-hand controls feature improved ergonomics, updated styling, and enhanced hand and thumb warmer control. The controls are easy to operate with gloves on, and have an improved tactile feel.
LED Lights
All models built on the AXYS® platform feature standard LED headlights. LED headlights deliver the industry’s best lighting:
- Nearly 1 lb. lighter and high beams are 80% brighter than incandescent lighting.
- Color temperature or output of the lights (the “whiteness” of light, reported in Kelvin) is 5000K, closely matching daylight.
- LED headlights last the entire lifetime of the sled. A major durability enhancement over traditional incandescent headlights which experience filament burn out.
- For constant visibility and enhanced safety, the low beams remain on at all times. Even when the high beam is activated, there is never a period of no light.
Wind Protection
The hood and windshield designs produce significantly enhanced wind protection for a rider, and the foil on the side panels further enhances protection.
Integrated Storage
Storage was designed and developed right along with the AXYS platform, so it installs securely and features seamless, integrated styling that matches the sled’s design lines.
- Compression-molded materials provide semi-rigid storage and enhanced styling
- Sturdier zippers provide better cargo security and protection
- Installs without tools
Premium Fit & Finish
Interfacing surfaces between body panels and components are shorter for minimized gaps
- Interfaces are strategically located in recessed areas
- Styling of storage elements results in clean, integrated lines
- Components are engineered for functionality and styled for the best styling
