I was impressed!!! My F5 snopro had great acceleration and awesome midrange... The suspention was alittle soft like everyone says... but it rides very nice. After a few miles the coolent light turned on so i stopped and let it cool good thing I was close to home... I needed to burp the baby.... I own a 2002 Polaris XCSP 500 and I switched and rode it. Man o Man There was quite a difference in the two brands... I punched the Cat and it was gone, the polaris took a little longer to get up and go.. The track and gearing made a difference I think. I am trading to the 1" track hopefully it will be this awesome on the top end too.
