Polaris® redefines Terrain Domination® With the All-New AXYS Platform on 2015 RUSH and SWITCHBACK Models
Five short years after Polaris shocked the world, reinventing the snowmobile by introducing the PRO-RIDETM chassis on the RUSH model, the brand with a track record of 60 years of Terrain Domination® is doing it again.
Polaris engineering, innovation, manufacturing capabilities and passionate understanding of what real riders really want have led to the all-new AXYSTM platform, the next-generation premium performance platform that is rider-balanced for terrain-dominating control.
Polaris began development of the AXYS platform with a clean sheet of paper and a simple goal: To radically raise the bar in the three dimensions that define world-class snowmobiles: Control, performance and comfort.
The all-new AXYS platform delivers the ultimate riding experience:
• Rider BalancedTM Control
• Unrivaled Acceleration
• Rider-Centric Comfort
Polaris is introducing a total of nine new 2015 RUSH and Switchback models built on the AXYS platform.
The foundation for the AXYS platform is an all-new chassis. This all-new chassis is built from the ground up with 93% new parts, including a carbon-fiber overstructure. The new chassis structure and design make 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 BalancedTM 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 Polaris® get there?
1. Put the rider in the right location on the sled.
2. Centralized the vehicle mass.
3. Optimized the suspension geometry to better control pitch.
Rider BalancedTM means putting the rider in the perfect position on the sled. The new chassis does just this, resulting in maximum control and maximum fun factor – at the same time.
On the new chassis, the rider is moved forward to a more balanced position on the sled. The rider’s hands are moved 4.5" forward, the feet are 2" forward, the knees are 4.5" farther forward, and the seat is 4.5" forward to put the rider in the perfect position to enjoy complete control of the sled and a great ride.
In neutral riding position, the AXYSTM platform allows the sled to corner like it’s on rails with very little tip in the corners. When the trail gets rough or the rider jumps off into the powder, rider balance then enables the rider to move back and make the front end light to climb up on top of the snow or the moguls.
This perfect balance is unequaled by rider-forward competitors whose sleds can handle unpredictably in the rough, or can exhibit excessive ski-pressure on-trail, effectively diminishing the fun factor. Polaris delivers balance where others deliver forward bias.
Centralized Vehicle Mass
Vehicle mass is more centralized on the new chassis, enhancing cornering and control. The rider experiences easier and more precise handling.
Suspension Design & Positioning
The completely redesigned geometry of the all-new PRO-XC® progressive-rate rear suspension is optimized for the best performance and Rider BalancedTM Control. Through innovative Polaris engineering and construction, the suspension is both lighter and stronger.
• It features a lightweight, forged aluminum rear crank.
• It has a completely redesigned crank and pivot.
• The front torque arm was moved rearward. This helps control pitch, increase travel, and
improve the rail profile.
The all-new PRO-XC® suspension delivers Active Pitch ControlTM. With Active Pitch Control, pitch is controlled by the suspension geometry and not simply by a high spring rate. This makes the sled less sensitive to adjustment while allowing optimal weight transfer.
As a result, the PRO-XC suspension delivers improved performance in ALL conditions, at all speeds. In big bumps and stutter bumps, at high and low speeds, the more compliant suspension setup produces:
• Flatter Cornering: Inside ski lift is significantly reduced.
• Chatter Bump Control: Control through chatter bumps is significantly increased. The front
end of the sled stays planted even when accelerating through a corner.
• More-controlled Weight Transfer: A rider can enjoy strong, high-acceleration launches without any compromise in cornering precision.
The AXYSTM platform delivers exactly what every rider craves: more power and less weight, resulting in unrivaled, class-leading acceleration. Polaris® achieved a 15% improvement in the power-to-weight ratio on AXYS.
• Class-leading acceleration and speed through the 1⁄4 mile
• Class-leading 0-60 mph
• Class-leading corner-to-corner acceleration for 30-50 mph
*Based on internal Polaris testing utilizing MY14 competitive product.
• With its clean-sheet approach to developing the AXYS platform, Polaris engineers
minimized weight throughout the sled without compromising strength.
• Selected models are up to 38 pounds lighter than they were on the previous chassis.
• The 2015 RUSH on the AXYS platform weighs at least 30 lb. less than a competitive trail
• While the weight was reduced, the sled’s strength, durability and reliability were maintained
New 800 H.O. Engine
Developed in conjunction with the AXYS platform, the new 800 H.O. engine delivers outstanding power and its integrated mounting position optimizes the balance of the chassis.
It features a high-efficiency intake and exhaust – including a 3-stage electronically-controlled exhaust valve. This delivers:
• Improved running quality and quieter ride
• Automotive smart actuator that provides feedback to the ECU for more accurate position
• Fuel economy improvement
The electronic oil pump eliminates power-robbing gear drive – and provides more precise, improved oil delivery.
• 35% reduction in throttle effort
• More accurate & consistent oil delivery
• Altitude and temperature compensating
• Features diagnostics and failsafe
The engine weight was reduced by 3.5 lb., including a lightweight new engine mounting system and innovative, lightweight new materials that help reduce noise and weight.
Thermostat with Bypass:
• Warms up to operating temperature 40% faster
• Water flows through the engine at all times
• No possibility of cold shocking the engine
New Throttle Body:
• Lighter weight
• Reduced throttle effort
• Improved TPS location & orientation to prevent water intrusion
Improved Engine Air Flow
Polaris® drivetrain engineers optimized the airflow in the new 800 H.O. engine with high- efficiency intake and exhaust and free-flowing, less-restrictive air flow, resulting in increased power output.
All-New Crankshaft = Enhanced Acceleration
The new, lightweight crankshaft provides the same balance as the previous crankshaft – with a 2.5-pound weight reduction in rotating mass. That produces a 25% reduction in inertia, improved throttle response and increased acceleration. The engine reaches its optimal operating RPM faster.
In the 2013-2014 snocross racing season, this lighter crankshaft delivered holeshot-winning enhanced acceleration for Polaris snocross racers. Recreational riders will experience enhanced acceleration from corner to corner – plus the engine delivers significantly improved fuel economy at trail speeds.
The AXYSTM platform also raises the bar for rider comfort. Rider-Centric highlights of the AXYS platform include:
Integrated Storage: Storage was designed and developed right along with the AXYS platform, so it installs securely and easily, and features seamless, integrated styling that matches the sled’s design lines.
Enhanced 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.
Improved Left-Hand Controls: The new left-hand controls feature improved ergonomics, updated styling, and enhanced hand and thumb warmer control. Controls are easy to operate with gloves on, and have an improved tactile feel.
More Comfortable Seat: The new seat utilizes a new high-performance seat foam, and the seat design is narrower in front to provide greater maneuverability. The seat is easily interchangeable with an accessory 2-up seat for true 2-up seating.
Longer, Larger Running Boards: The new seat is complemented by wider running boards that give the rider more options in foot and leg positioning. RUSH® running boards have 15% more space, Switchback running board space is increased by 11%.
Industry’s First LED Premium Lighting: Models built on the AXYSTM platform feature the industry’s first LED headlights as standard equipment. New LED headlights deliver the industry’s best lighting for significantly better visibility. Model Year 2015 AXYS LED lights are 30% brighter and nearly 1 lb. lighter.
Industry-Leading Color LCD Digital Gauge: Another industry first for Polaris®, the AXYS 60th Anniversary models feature the most advanced instrumentation in snowmobiling.
Premium Fit & Finish: Interfacing surfaces between body panels and components are shorter for minimized gaps.

Thanks to 4Nines for the best summary of the AXYS features and benefits that I have seen on the internet, including the Polaris corporate websites!
Just want to point out that the new 800 H.O. engine is ONLY available in the AXYS chassis. It has special attachments for the motor mounts built into the motor castings, and would not install easily in a stock 2010-2015 PRO-RIDE chassis. Also the routing of the intake and exhaust are different.
UPDATE here is how the 3 stage electronically controlled Exhaust Valves work:
The valves are closed up to 6200 rpm.
at 6200 rpm the first stage opens.
at 7200 rpm the second stage opens.
The Electronic oil pump is controlled by the Engine Control Unit computer, so the potential for sophisticated oil delivery is there. In addition to throttle position and rpm, altitude and temperature are also used by the computer to decide how much oil to inject into the engine.
Sources in Polaris have identified problems that began during warmup on the 800 Cleanfire engine. The new system employs a thermostat that bypasses directly back into the motor, and can get the engine to operating temperature 40% faster. The coolant temperature readout on the Polaris IDD gauge will also make the rider aware of how warmup is progressing.
If you look closely at the section in post #1 regarding the 800 H.O. and the new lighter weight crankshaft, you will be able to understand how much is changed on this engine.
Reducing crankshaft weight by 2.5 pounds reduces its inertia (resistance to change in RPM) by 25%. This will allow greater acceleration.

The Polaris website now has some additional information about engine changes:
These are some of the features also in the new 800 H.O. I have not found pictures of this new 600, but it could look very similar to the 800 H.O. on the outside.Now in the AXYS™ chassis, the 600 engine features new lightweight integrated mounts, electronic oil pump and bypass thermostat.
This information is found in the "Overview" tab of the View the sled.
