I have an 07....it's a very nice sled to ride, and I had lots of fun on it last year. I will be keeping it through this year. Problems I have had:
- 07 motor blew at 500 miles....replaced with 08 motor under warranty and all is good so far (at 1200 miles now)
- Clutch bushings wear out quickly, clutch is finiky to fine tune and doesn't like to run day in/day out consistant RPM like the Polaris I came off of....
- Had a throttle position sensor go back (under warranty, but it cost me 2 or 3 rides)
- Challenger Lite track (if equipped) falls apart quickly....at 1200 miles it looks like my Polaris track did with 4,000+ miles
- Chaincase exploded (warranty)....I would say that was a freak occurance tho
Overall I would say good sled but somewhat tempermental. The upside is, they are a great buy on the used market. If you get a good deal, it's a LOT of sled for the money and will run with any of the 08-09 stuff no prob. I rode with new Cats all last year and it was the same thing....a primary clutch with cracked spider, blew a diamond drive, low/high RPM. They (sleds) all kinda suck, but at least the revs are fast LOL
