From some experience of bike reviews in a previous life, a couple of things stand out in hindsight (and indeed were fairly obvious at the time). First, the emphasis for the testers is firmly on performance, and it can't be any other way. You ride the bikes as the importers present them and you get a good sense of how they compare from a performance standpoint - indeed, a better sense than most owners ever get. What you cannot say much about are the broader aspects of ownership. Reliability? You can speculate, but given it is speculation you can't say much without risking inaccuracy and hence unfairness. Running costs? Same, really. Even intangibles such as character resist comment because they are so much in the eye of the beholder and because the relatively short time spent on each bike doesn't allow a deep appreciation to build up. Second, even with respect to performance, it is easy to be worlds away from the owner experience. So many apparently minor aspects of set-up affect the performance of modern bikes. They steer differently on different tyres, an aftermarket rear shock transforms the suspension, different brake pads transform the brakes, etc. With adventure tourers, all this is magnified compared with, say, sport bikes, and you have the added difficulty that typical conditions of use will vary so widely from owner to owner. Nevertheless, I still enjoy reading what the testers write about the bikes. Life would be poorer without all this. IMO. You can also find a bit of stuff to read between the lines.
