Features SC-5U REAR SUSPENSION: Our sport-utility suspension. Refined ride both on trail and on top of powder. Articulated rail to maximize deep snow traction in reverse or locked out when towing. REV-X PLATFORM: Extremely light, yet strong with a riding position for superior maneuverability in deep snow. ROTAX ACE ENGINES: Both the 900 ACE and 600 ACE four-strokes use Advanced Combustion Efficiency Technology to deliver brisk performance, excellent fuel economy and ultra-low maintenance. The 900 ACE is rated at up to 21.8 mpg, 10,8 L/ 100 km)* and the 600 is the most efficient in snowmobiling at up to 29 mpg (8 L/100km). Proven Intelligent Throttle Control (iTC) throttle-by-wire technology opens up a new world of customization and drivability options. Includes three shift-on-the-fly driving modes (Sport, Standard, ECO), Learning Key feature and optional finger throttle operation. FINGER THROTTLE (ACE ENGINE ONLY): The throttle block can be rotated forward for use as a finger throttle, if preferred. Great for changing hand positions on a long ride and for more control in bumps. PILOT DS 2 SKIS: Single-keel with excellent sidehilling bite, thanks to thin outer edges. Narrow and thin, yet stiff. Shorter behind its complementary spindle with flat tail for easier counter-steering and sidehilling. DUAL A-ARM FRONT SUSPENSION: Advanced geometry keeps the skis firmly planted – no matter the conditions – to deliver precision and control. ANALOG GAUGE WITH DISPLAY: Smartly-styled analog speedometer and tachometer plus LCD digital information screen.
