In the summer of 2019 i purchased a 2009 500ss with only 1900 miles on it for my 2019-2020 season. I was very skeptical but have read a lot of reviews on the sled but most of them were old, from when then sled was new. I decided to write my own 10 year review. This is a badass sled. Its light weight (only about 500lbs dry). Easy to maneuver around the deep snow. You dont feel as tired after a long day of trail or off trail riding because its not as heavy as most sled. It's got a strange amount of power for a 600. Lifts the skis right off the ground with ease! Starts 1st or second pull every time. I weigh 180lbs and have gotten the sled up to 85mph. It was still pulling but not that hard. Im sure with someone smaller on it it would go faster, but you're not doing 85mph in the trails anyway so crusin 50-60 is just fine. I've ridden/owned 440s-900s of every brand sled and this is by far my favorite sled. I would recommend this sled to anyone.
