Since we gave the Indy 800 XC SP variable exhaust, it has two basic throttle positions - idle and gone. It has more performance throughout the powerband including a spectacular 12 horsepower gain at 6,000 RPM. Other new features include easier starting and new race proven gas shocks on the front suspension. The Indy 800 XC SP rides on our race-proven EDGE? chassis which gives you an industry leading 13.9' of rear axle travel and our exclusive Position Sensitive rear track shock underneath. Up front, EDGE? has 10.3'of travel, with our Controlled Roll Center design and a wide 42.5' ski stance which are some of the reasons SuperTrax magazine called it 'the best-handling Polaris ever.'
