SKIS AND RUNNERS
The skis on your Ski-Doo are not flat on their bottoms, they are slightly convexThis is done to improve stability at high speed on straightawaysThe plastic ski on the MX and MX incorporates more of its use (rocker effect)This plastic ski will work very well on snowy surfaces as it increases flotation and reduces dragFor oval and Ice Lemans, the new profile is superior to the steel skiA B
