2010 - They said it was impossible to break three pounds per horsepower. That’s exactly why we did it. The 2010 Summit. A perfect example of what can happen when innovative design meets advanced engineering. Built on the impossibly light yet strong REV-X platform, Summit remains the only mountain sled to break three pounds per horsepower. Translating to easier climbs, higher highmarks and the ability to boondock where others wouldn’t dare. Just another way that our engineers and designers are keeping Summit exactly where it belongs. On top. Summit Everest - the mountain performance standard.
