Some people are just scared of all motorcycles, even 50cc mopeds with a top speed slower than an Olympic sprinter. But there exists a handful of bikes with a reputation of being frightening, not just among the general public, but with trained professional riders and members of the moto-press alike. Nowadays with every commuter bike having over 100hp and the ability to top “the ton” easily, it can be hard to see what all the fuss was about on some of these. You have to remember though, when many of these bikes were new engine power was way ahead of suspension and chassis design, and brakes and tires were not even up to the standard of today's cheap mountain bikes.
