5—Ski-Doo Summit SP 600R 154
The Summit SP 600 is in my top five mostly because of the new powerplant. And you can get it with SHOT. The new Rotax 600R E-Tec engine is crisp, plenty powerful for a 600 and features that same smooth powerband you find on the Rotax 850. And it comes with many of the very things I like on the bigger Summits, like the PowderMax with FlexEdge track and Rev Gen4 platform. Hands down though, I prefer the 154-inch track over the 146.
6—Polaris 850 Pro RMK 155
See No. 3 because I pretty much have the same feelings for the Polaris 155 as I do for the 163. A strong engine to match the AXYS chassis. There was a time that the mid-150s tracks were my favorite and I was steadfast in that … until the 160s came along.
