Then we went back up top and switched for a 2018 Gen4 Summit 850 175. The first thing we noticed was this sled doesn't lose grip on sidehills. We could move our feet back a little farther for a more manageable rider position. This changed how we looked at tree lines, because we weren't lining up and rocketing through gaps. Instead, we could drive through them in total control, pick new angles either up or down, and keep on driving.
The second thing we noticed with the new sled is how much lighter the 2018 Summit 175 feels and rides than a 2016-17 Summit XM 800 174. Most of this obviously comes from the new Gen4 chassis updates and improved power and response from the 850 ETec engine. Either way, it feels like more of a completed machine.
