Thank you. As a biker I really dislike bikes made lout just to be made loud.

No, it doesn't save lives, most serious accidents are being t-boned on the junction, the car failing to yield to the biker with priority, biker losing control over the machine, or biker being reckless.

Most of it (at least in the UK) is attributed to ineffective observation, which in case of the bikers means education (training) and better visibility (special lights, bright coloured jacket and helmet).

Not a deafening ride.
