Overview of the Kore X 90
Overview of the Kore X 90 The Kore X 90 is a 90 mm waist all‑mountain ski from the Kore family, built for versatility. It targets skiers who spend most of their time on groomers but want a single ski that can handle chopped snow, occasional off‑piste laps and light powder. The tip‑and‑tail rocker with camber underfoot eases turn initiation while maintaining edge hold and rebound. In short, the Kore X 90 is designed as a do‑it‑all ski that leans slightly freeride while staying very capable on‑piste.
On‑snow performance
On‑snow performance On groomers the Kore X 90 feels lively and precise: camber underfoot provides good grip and pop, and the carbon‑reinforced layup keeps the ski responsive. Shorter lengths shine in quick, playful turns while longer lengths deliver stability at speed. In chopped snow the ski tracks well and remains controllable. In deeper, heavy powder the 90 mm waist limits flotation compared to wider freeride skis, but it still handles light fresh snow confidently thanks to the rocker profile.
Construction, materials and weight
Construction, materials and weight The ski pairs a lightweight Karuba‑poplar core with multilayer carbon and graphene reinforcements, giving a high strength‑to‑weight ratio and snappy feel. The sandwich‑cap style construction balances durability with direct energy transfer to the edges. A structured UHM C sintered base offers good speed and wax retention. Weight is competitive for its class (retailer listings report ≈1,970 g per ski at 170 cm), making the Kore X 90 agile and less tiring on long days.
Specs and what they mean
Specs and what they mean Available lengths: 156, 163, 170, 177, 184 cm. Sidecut and radius change by length (e.g., 130‑91‑113 at 170 cm, ~14.7 m radius). Tip ~124–136 mm, waist ~87–95 mm, tail ~108–117 mm depending on size. Narrower waist aids quick edge‑to‑edge transitions and firm‑snow carving; larger radii in longer skis favour smooth high‑speed turns. Rocker in tip and tail improves turn initiation and soft‑snow flotation, while camber underfoot preserves edge grip and rebound.
Verdict — who should buy it
Verdict — who should buy it The Kore X 90 is ideal for intermediate to advanced skiers wanting one versatile ski for varied conditions, offering lightweight agility, good edge hold and playful behavior. Pros: light, responsive, well‑rounded for on/off‑piste days. Cons: limited deep‑powder performance and slightly less damping at very high speeds than heavier freeride skis. If you need a true powder specialist, look to wider models; if you want a nimble all‑mountain performer, this is a strong pick.
