Motor Cycles (Noise) Mr. Nicholas Baker asked the Minister of Transport what action he is taking to restrict noise from motor cycles imported into the United Kingdom being emitted noise above permitted noise levels; and if he will bring forward proposals to reduce the permitted noise level for motor cycles. Mr. Kenneth Clarke Enforcement of the current noise limits for motor cycles is primarily a matter for the police. However, the condition of exhaust systems is checked as part of the MOT test which applies to them after their third year of life. Consultations have already taken place on proposals for more stringent noise limits for various categories of vehicles including motor cycles. It is hoped to proceed with the necessary regulations shortly.
