I can't speak specifically about European models but the counter balancer chain tensioner is a weak spot. If it breaks, serious engine damage can result and apparently it can break without the rider knowing. However, some people put viewing holes in the case to make sure it's ok after a routine chain tensioning sesion. I myself have never had any problems, though.
My 12K miles KLR uses little or no oil between changes. I'm very happy about that. It's been rock solid despite the abuse I give it.
Keep in mind, though, there is nothing hi tech about this bike but that's why its inexpensive.
