Whilst refueling yesterday at the Shell I saw this young guy arriving on a KTM 540 trail bike. When stopped, he couldn't touch the ground and next thing rider and bike are flat on the ground. Naturally I gave him a hand to stand up his bike and when I looked at him and the tall bike next to him I couldn't help but wonder: Why for Pete's sake would you ride around on a bike that is way too tall for you? Since the guy was already way to embarrassed I did not want to ask him the question. But I do wonder what motivates riders to buy a new or used bike which they can barely control when they are standing still. And why do the manufacturers make some of their bikes so tall ?
