Put about 40mi on the new 600 today. Gotta say I was pleasantly surprised. It definitely feels light and had better power than I expected. The throttle response was quick and crisp and the sled pulled very good. Can't wait to get into some steep and deep. I was riding in about 18" of fluff with no base whatsoever but still had some fun. So far, great sled, but need to really test it in some good snow. Oh yeah, and the hand warmers on high will burn your hands!
