Say what, a SuperSport? Polaris has been watching the likes of the Ski-Doo Freestyle and they had to jazz up their 550 as well with aggressive looks to capture the younger market. The 2007 SuperSport gets some of the eye-candy from the RAW RMKs and the Dragon, adding â€œboy racerâ€ sizzle to an otherwise traditional EDGE chassis. The 550 is now up to 60 HP with Nicasil cylinders and improved fuel economy. Does the seat look familiar? Itâ€™s the Pro X2 seat! The TEAM LWT secondary is in there, as are Nitrex gas cell shocks all around.
