Looking at upgrading to a newer machine and am wondering if there are any quirks or flaws with any years of the 570’s? What year did they start selling it? I am very familiar with the 97-05 sportsmans. Completely restored 3 and currently working on a ‘01 6x6. Only ridden/owned 500’s and a 335. Would go after an 800 or 850, but the newer 570’s come up regularly and are pretty affordable with only 1k miles or so. Have heard of some 570’s overheating, but not sure if it a year range or Why they overheat. Thanks.
