My wife is going to look at an 08 600 SDI tomorrow, with a 144x2 track I know nothing about these sleds, it has about 700 miles on it, a cousin of hers looked at it (it is out of town) and said it is in showroom condition) Is there any known issues with these? Are they reliable? How easy are they to ride? And could someone post some pics of one? Are they a 16" track? Thanks for any info.
