The 800 Polaris® Titan™ SP is agile and versatile and features the Ripsaw track with 1.375 inch lugs, high-flotation PRO-FLOAT skis, and Polaris IFP Shocks. AXYS® Rider-Balanced™ Handling & Performance AXYS® Rider-Balanced™ Control: The AXYS® Titan™ Chassis positions the rider for Rider-Balanced™ Control in all riding situations - solo, 2-up, with cargo on-board, or towing a load. This platform delivers unmatched ride & handling on- and off-trail. Balanced handling on all terrain; Superior mobility, agility and performance in deep snow; Ride & handling are not compromised when hauling or towing cargo 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.
