Motorcycles have been widely used as private transportation
means, but are now confronted with difficult situations to meet
increasingly stringent noise control regulations which requires
various noise abatement technologies.
Manufacturers, on the other hand, are required to produce
totally balanced motorcycles overcoming restrictions in space,
To cope with this situation, utilization of high techniques for
measurement and analysis of noise is indispensable including those
for detection of noise sources in order to take effective noise
Well balanced motorcycles must be protected from tampering or
improper maintenance, and it is essential that noise control
regulations must be technologically feasible in view of the
situation in each country.
