Ski-Doo knew they needed to add some more zip to the package to attract even more buyers. The single-popper 300 is now called the Freestyle Session (also offered with the 550). New models include the 415 pound Freestyle Backcountry (136â€ x 16â€x 1.25â€) and Freestyle Park (121â€ x 15â€ x 1.25â€), powered by a (60 HP) 550 fan cooled twin with revised port timing for improved low-end torque. Off throttle response is quite fun, with plenty of zip to pop up and over whatever you choose. HPG shocks front and rear improve suspension capability. Only the 300 has the narrow 32.2â€ stance, all 550s are at 39â€.
