The 2019 Polaris snowmobile lineup is loaded with innovative technology, including the all-new Polaris 850 Patriot engine, exciting new INDY 129 models, new technologies on the industry-leading PRO-RMK deep snow models, and the new INDY EVO model, designed specifically for new riders.
All-New, SnowCheck-Exclusive Polaris 850 Patriot Engine
The Polaris Liberty engine lineup is expanding with the introduction of the all-new Polaris 850 Patriot Engine, a powerful new member of the Liberty family that includes the 600 Cleanfire and 800 H.O. Cleanfire engines.
With the knowledge gained from 25 years of legendary Liberty engine manufacturing, the Polaris Powertrain Team started with a clean sheet and a focus on durability as it developed the all-new Polaris 850 Patriot engine—the most powerful Polaris snowmobile engine ever. Proven through extensive and demanding testing, this engine is incredibly durable and reliable—and it is backed by a standard 4-year warranty. The new liquid-cooled 850 twin delivers class-leading Durability, Acceleration, Response, and Power.

Note: Data based on internal Polaris testing
The Polaris 850 Patriot engine is all-new: The only parts used on any other Polaris engine are the spark plugs, two sensors and some common fasteners. This includes the new Patriot strategic engine mounting system that was designed to integrate with the AXYS architecture. Minimum vibration is delivered to the rider and belt life is maximized.
The Polaris 850 Patriot engine includes an all-new, high-performance, high-durability piston featuring a higher compression height and thicker dome. The all-new, low-inertia crankshaft is designed to be both strong and stiff while maintaining low weight and inertia for ultimate response. The crankshaft features advanced, high-capacity bearings and a larger clutch taper design. The new lightweight throttle bodies feature a simple, durable design, while a contactless TPS ensures reliable, consistent performance, with no adjustment required.
Developed using Computational Fluid Dynamics (CFD), the cylinder and cylinder head designs are optimized for strategic cooling and feature patent-pending designs for the combustion chambers and exhaust ports. A patent-pending water bottle-integrated thermostat maximizes durability and cooling efficiency. The innovative thermostat design is simpler and more durable.
The new electrical system delivers peak efficiency with its power-boosting regulator that ensures quicker starting and helps deliver maximum electrical power at idle and low rpm. The new ECU features a faster processor, exhaust valve control integration and provides more input and output capabilities.
This all-new engine features many other all-new technical components including a new 3-stage E-VES-II exhaust valve system that features a simplified coplanar valve with fewer parts and lighter weight. A new exhaust system—pipe and resonator—provides improved flow and sound quality. And the VForce reeds were designed specifically for this engine and have new carbon fiber petals for improved performance.
This new engine is available in select models across the RMK, Switchback, RUSH and INDY line-ups exclusively through SnowCheck. Polaris will also continue to offer a line-up of proven, high-performance Liberty engines, including the 600 Cleanfire and the 800 H.O. Cleanfire engines.
Polaris INDY Family Expands With Exciting New Models, Technology: INDY EVO, INDY SP 129, INDY XC 129
The Polaris INDY family expands for 2019 with the introduction of the all-new INDY EVO and the INDY 129 models.
The new INDY EVO is a trail-ready snowmobile built specifically for new riders. The INDY EVO delivers a comfortable, sporty and confidence-inspiring ride experience that will fuel a new rider’s passion for snowmobiling. The sled is engineered so it can evolve in stages with riders as they gain experience. An accessory is available that lets the sled grow with the rider through increased power and suspension capability.
The all-new INDY 129 models—the XC and SP—deliver Rider Balanced Control, precise handling, and the highest fun factor. These versatile new models are built on the proven, lightweight AXYS Chassis and introduce the all-new PRO-CC 129 Rear Suspension that provides trail riders with outstanding ride, unrivaled acceleration and the versatility they need.
The SP and XC models are truly purpose-built:
- INDY SP 129: Trail Performance. Available with the 600 Cleanfire engine.
- INDY XC 129: Premium, High Performance Trail. Available with the 600 Cleanfire engine, the 800 Cleanfire H.O., or with the SnowCheck-exclusive new 850 Patriot engine.
The all-new PRO-CC Rear Suspension is the next-generation suspension from Polaris. It produces class-leading acceleration, a smooth ride and flat cornering. The rear suspension’s coupled design controls pitch through geometry without reducing the fun factor Polaris riders have come to expect. Race-proven Walker Evans Velocity and Needle technology shocks are featured on INDY 129 XC models and have improved clicker accessibility for the easiest adjustability.
These new models feature new PowderTrac TR extruded aluminum running boards, new lightweight XT Hyfax, a choice of aggressive tracks and the expanded versatility of accessory seating and storage options. The new INDY 129 models can be converted quickly and easily from solo seating to 2-up seating with the accessory passenger seat with handgrips. INDY 129 models come with a standard underseat storage bag and several other accessory storage solutions are available that can be used with or without the passenger seat.
New PRO-RMK React Front Suspension
Polaris RMK models are the world’s greatest mountain sleds. They are the lightest, strongest and most flickable deep snow snowmobiles available, and for model year 2019, these sleds have been elevated to the next level of performance with the all-new AXYS PRO-RMK React Front Suspension, new PowderTrac XT Running Boards, new lightweight components, and are available with the most powerful Polaris snowmobile engine ever, the all-new, SnowCheck-exclusive, Polaris 850 Patriot engine.
