Vintage riders know just how far snowmobiling has come with front suspension comfort and how it affects handling and safety. Snowmobiles from the leaf spring era, which was pretty much from the beginning right up to the 2011 Yamaha Bravo, relied on a variety of front suspension technologies that really didn't change much over the decades. When Polaris first adopted the trailing arm independent front suspension (IFS) for what would become the most popular line of sleds in snowmobile history, the leaf spring remained relevant in every snowmobile line of the period. Where the leaf spring design had become a staple, alternative suspension concepts were unsettled.

i remember early 70's RUPP's had leaf spring with a shock on the side, my 73 ski doo TNT silver Bullet had leaf springs with the shock on top....i thought that was ahead of it's time back then! my buddies all had ski doo olympique's with no shock and the ski's would flop all over the place...plus when 2 people sat on the Olympique's the ski's barely touched the ground,lol .....ahh the good ole days!
