Does anyone know of any issues to look for when buying this model used?
Specifically the 2011 vintage. I've read that the drive shaft could possibly rust internally but that could have been fixed in the later models.
I purchased a 2009 m50 about 8 months back and have been happy with the purchase. There have been no problems to date, so other than the shaft drive issue reported in this forum, I don't have any worries recommending the bike.
