Ok, so I've now got 5,460 miles on '09 Versys that I bought May 25th, 2012. Had the oil changed at 600 miles, since then I've changed it four times. Nov. of '12 I changed it before winter, even though I still rode it another 600 miles over the winter. Then June of '13 I changed it, rode all summer, then changed it again in Oct. Only rode it maybe 200 miles between Oct. and this past Mem. weekend when I changed it again. Friend says overkill, 5 changes in less than 6K miles. I say I'm being cautious since the bike sits most of the winter, plus when I do ride, it's primarily to/from work, about 30 miles rnd trip.
