You don't actually have to plug the K2 Amp Rictor 90 XTi Ski in to get it to work, because it supplies plenty of power all on its own. At 90mm underfoot, it splits the size difference between all-mountain and freeride skis, with a construction that's as comfortable plowing through soft snow as it is railing top-to-bottom turns down groomers. Built from aspen, paulownia, and maple for the perfect combination of lightness, stiffness, and liveliness, the Amp has a moderate turning radius to keep things manageable in tight spots as well as on open slopes, and a Titanal laminate that helps it rally at top speed and bust through crud without getting jittery or unstable. K2 built the Amp using its All-Mountain Baselin 2. 0 technology, which matches the rocker and sidecut profiles to provide a big sweet spot for all turn shapes, a short, rounded tip for predictable turn initiation, and blunt, round tail for easy turn release in all conditions. Combined with the traditional camber underfoot, this allows the ski to hold or release an edge whenever you want, so you can rally down hardpack or stay quick and nimble in the trees. The Power Tip also helps the Amp plane up and over soft snow, and the Hybridtech sidewalls combine traditional sidewalls and lightweight cap construction for durability, edge hold, and smooth turn initiation. The Amp even has Z-Clip skin grommets, so you can stick some K2 skins on and rip some backcountry lines if you get tired of crushing the frontside.
