Ski-Doo enjoyed great success with their 550-fan powered X-package, the only X-package that was offered all season long. This is an economical way to get the technology from the race department in a super-light (435 lb) sled that doesnâ€™t break the bank. More features have been added for 2007, with upgrades found in the suspension, track and seat. Clicker Take-Aparts up front, Take-Aparts in the rear (no clickers) and a Rip Saw track is standard. A 440-style seat gives it showroom appeal that is, well, it looks pretty damn hot. Your wife might even get jealous.
