Ski-Doo has revised their Pilot 5.7 skis, with reinforcements added to strategic locations, including the thickness on the outside edge just in front of the outer carbide runner. This is certain to improve durability and strength of the otherwise well-mannered skis.
When it comes time to replace the Pilot 5.7 skis on a 2006 model, be sure to get the 2007 ski bottoms; LH 505 072 165; RH 505 072 164.
The wider Pilot 6.9 skis have been enhanced for 2007 as well. They also get similar reinforcements to the ski bottom, but now they use a single square carbide runner on the center keel only as part of the Summit weight reduction for 2007. An additional carbide runner may still be added to the outer edges for aggressive riding in packed conditions.
