All these friggin rule changes are a joke! Has the commission nothing better to do than look for POTENTIAL problems? If so, what are they doing in their role? Surely they should be looking at ways of improving the sport and making it EASIER to compete, not adding more rules that do nothing to improve the sport and only frustrate the owner/rider of the bike(s).
I've seen fingers chopped off at work. I've seen fingers chopped off at ice skating. I've seen a bloke stabbed through chest with his own surfboard. Pedestrians get bowled over all the time. Bike riders get cleaned up on a regular basis. People trip over chips in shopping centres......and on it goes. Point is, you can't stop stupid from being stupid and you can't wrap society in cotton wool.
Yes, people get injured riding and even working on motorcycles, but that's the way it has always been and no stupid rule(s) is ever going to change that.
I won't be fitting any chain guard to any of my bikes. PERIOD
