BMW has initiated a recall on 2012-2014 C600 Sport and C650GT scooters because of a problem with their timing chain tensioners. As of this writing, recalls have been announced in Canada and Germany but not for the U.S., though we expect the U.S. National Highway Traffic Safety Administration will announce a similar recall shortly.
According to Transport Canada, the timing chain tensioner may have been manufactured incorrectly, potentially allowing the chain to lose tension. Should this happen, it will make a noticeable noise and, if the scooter is operated, may result in an engine breakdown.
BMW dealers will replace the timing chain tensioner on recalled units. The Canadian recall affects 163 units.
Again, no recall has been announced as yet for the U.S. but we expect one to be announced in the near future. We will provide an update if/when NHTSA announces a recall.
