K2 AMP Richtor 90XTI 2015 Review by A Better Ski

The K2 AMP Richtor 90XTI is a great mix of frontside capabilities and all mountain freeride performance. It’s a versatile ski that is designed to charge anywhere on the mountain, and great for those who spend an equal amount of time on the frontside groomers and off piste. It didn’t blow us away in any one category, but rather surprised us with its overall versatility, and ability to take you just about anywhere you want to go on the mountain.

Size: 177

Days: 1

Riders: Matt

Conditions: Groomers, Hard Pack, Soft Spring Slush, Bumps

Boots: Rossignol Alias Sensor 120

Bindings: Salomon Z12

On the Snow Feel: The K2 AMP Richtor 90XTI has a stable feel to it without being locked in. The All-Terrain Rocker and low swing weight help to keep the ski maneuverable and easy to turn, but it’s not super playful or loose feeling.

Powder: The K2 AMP Richtor 90XTI has a long, low profile rocker that really aids in floatation in the deeper snow. At 90mm underfoot, it doesn’t have the same surface area (or float) as wider skis, but for the 90mm underfoot category, the Amp Richtor is near the top for float.

Turn Initiation and Carving: One of the biggest surprises for me was how easy it was to turn the K2 AMP Richtor 90XTI. The lightweight construction and long low profile rocker seems to reduce the swing weight, and with a tapered tip, turn initiation was smooth and easy. Even at lower edge angles and speeds the ski was responsive. I found it relatively easy to flex into the turn, but it didn’t have the liveliest or most energetic rebound. Rather, the ski was predictable, smooth, and fun. It seemed to cater more to the finesse skier, rather than someone who really likes to charge down the fall-line. Again, I wouldn’t say that rebound was bad, but just don’t expect the ski to throw you from edge to edge. Still, its low weight allows you to maneuver the ski with ease, and it still remains quite quick from edge to edge. It’s a capable carver with a smooth, easy going personality.

Speed: K2 designed the AMP Richtor 90 with their ROX technology that places a “secondary core” on top of the primary core. This MOD structure, as they call it, helps to increase the dampening properties of the ski, making it more stable at higher speeds. In addition, the K2 AMP Richtor 90XTI has two metal laminates above and below the core, increasing the overall dampness. At high speeds the ski feels stable, so long as the snow remains relatively smooth and soft. When encountering harder snow, or chopped up snow, the tip begins to chatter, and stopping at high speeds becomes a bit of a challenge.

Uneven Terrain: The K2 AMP Richtor 90XTI does a good job in the soft chop and crud. Here the softer flexing tip, and its low profile rocker, seems to do a nice job of absorbing terrain and smoothing out the ride. The skis isn’t going to blast through the crud like a heavier more burly ski, but rather floats over the top and absorbs the terrain. As things firm up, however, the ski becomes a bit more bouncy, and less stable.

Moguls: The K2 AMP Richter 90XTI is a quick and maneuverable ski. The tail is flat, and relatively stiff, so not the most forgiving, but it also releases easily, and helps power you into the next turn. The AMP Richtor makes a fine mogul ski, but you need to stay a bit more aggressive.

Edge Hold: The ski is built to be quite torsionally rigid, and provide better edge hold, but the long low profile rocker and tapered tip reduces the overall effective edge, almost cancelling out the benefits of the ROX technology. Edge hold is still good, but not exceptional.

Flex: The tip is a medium flex while the rest of the ski is quite stiff (longitudinally). This allows the ski to be forgiving, capable in the soft snow, and yet stable at speed and in the soft chop.

Switch: This ski is directional and best going forwards.

The K2 AMP Richtor 90XTI is a solid all mountain ski for those who like to spend an equal amount of time on the frontside groomers and off piste terrain. It didn’t blow us away in any one category, but has a well-rounded capability that can take you all over the mountain. It has some of the best float for a 90mm underfoot ski, and is good in the soft snow and crud. On the groomers it’s predictable and fun, but not super powerful and snappy. It’s solid on the frontside and solid off piste. The K2 AMP Richtor 90XTI is a good ski for those who like to ride the entire mountain.
