2025 K2 Reckoner KF

We always love seeing new pro models come through the test, and the 2025 K2 Reckoner KF is a good one. Based on athlete Karl Fostvedt and his proclivities for launching huge jumps and taking big lines, the KF brings a different approach to the Reckoner line without changing it completely. For normal powder skiing and playful attitudes, the Reckoner skis do just fine, but if you’re a top-level athlete who’s seriously pushing the boundaries of what’s possible on the snow, you may need something different. This is where the Reckoner KF comes in. They take the base character and personality of the Reckoner series and put in some hard-charging and deep snow capabilities. The result is a stiffer Reckoner that floats, plays, charges, and crushes. The new KF puts a wonderful spin on an already wonderful line of skis.

While K2’s catalog lists the wood core to be TBD in terms of material, it’s safe to assume that at least some aspen will be involved as that’s the backbone wood for most of K2’s skis. The big change here is that instead of their normal carbon boost braid, we get a total carbon braided core. This adds considerably more carbon to the mix than any other Mindbender ski, boosting stiffness and response. In addition to this full layup, we also get the normal carbon spectral brad that buts more torsional stiffness in the underfoot zone and a looser flex in the tips and tails. Even more carbon is on the menu for the KF, inserting Carbon Boost stringers and uni-directional flax to the mix. Basically, all carbon applications are used here and then some. This is in an effort to keep the ski stiff and precise while also remaining light and mobile. Freeride coach Noah Novotny states that the KF is “Very playful and more stable than I would expect. It was stiff enough under foot to ski crud at speed and other freeride terrain.”

In addition to the build being very different, we get a new Reckoner shape as well. This ski boasts measurements of 137/114/134 mm, giving it that symmetry that Reckoner has been known for. This produces a turn shape of 23-meters in the 184 cm length, putting it on the slightly longer side of the spectrum. With freeride skis like this, it’s nice to have a bit of extra straightness to put your own spin on the turn shape and style. KF gets K2’s Powder Twin Rocker profile that is very extended with high rise splay and long length rockers in both tips and tails. This adds to the overall flotation and soft snow performance. Noah continues to note that this ski is best for “Powder snow and other freeride terrain. A great ski for catching air and doing tricks. The more progressive mount point and 114 width mean it wants to do tricks into powder.” That sounds like typical Fostvedt stuff to us.

As a result of the pro-based build and innovative shape, this Reckoner KF is more of a specific ski, as most pro models are. Whether Karl is a hero of yours or if you’re simply a collector of all pro-model skis, this Reckoner is a unique ski and an interesting choice. With the specific carbon applications involved here, it does separate from other Reckoners in terms of flex, so do not expect simply a different width Reckoner—this is a totally different ski with very specific intentions.
