This from the DfT:[/size]"Motorcycle noise can be especially intrusive. Existing maximum noise limits for motorcycles are significantly higher than for cars, and even from June 1999, when a more stringent 80 dB(A) noise limit will be applied to new motor cycles over 175cc, limits will still be 6 dB(A) higher. These relatively high limits reflect the limited scope on motorcycles for cladding and other noise suppression techniques. Furthermore, the fitting by some motorcyclists of inappropriate or altered silencers, mainly on older machines, can exacerbate the problem of motorcycle noise. The UK now has one of most stringent series of regulations in force to control both construction standards for, and the sale of, replacement silencers for motorcycles."[/color]
