A national summit conference on the issue of motorcycle sound involved
40 representatives of the street and off-road motorcycling communities,
as well as motorcycle manufacturers, aftermarket companies, event organizers,
law enforcement, municipal government, research institutions and regulatory
agencies. Participants were invited to participate in this face-to-face
discussion hosted by the AMA, and considered various aspects of the
issue in a series of seminars and open discussions. They agreed to continue
those discussions in the coming months.
"We're pleased that this important dialogue has begun, and we believe
that it's a promising beginning," said Robert Rasor, AMA President.
"We're grateful to all those who shared their perspectives, helping
American motorcyclists to address this issue in positive and constructive
SUGGESTED ACTION ITEMS FOR ON-ROAD MOTORCYCLES
- Representatives of the American Motorcyclists' Association and the
Motorcycle Riders' Foundation will draft a clear statement on motorcycle
noise and the need for riders to behave in ways that will not damage
the quality of the lives of other citizens. The statement once endorsed
by the Boards of AMA and MRF will be offered to State Motorcyclist
Organizations and other riders groups for their endorsement.
- Manufacturers of motorcycles and their original equipment will be
invited to become parties to the Agenda. This will require a range
of measures be taken by manufacturers to assist in the resolution
of the problem of motorcycle noise. The manufacturers participating
in the Sound Summit recognize that in the development of the measures
it will be appropriate to consult with and involve the main riders'
organizations and other interested parties.
- The aftermarket industry, including both the manufacturers and suppliers
of aftermarket parts and equipment will be invited to become parties
to the Agenda. As with the manufacturers of motorcycles and original
equipment this will require them to develop effective measures that
will assist in the resolution of the motorcycle noise problem. In
so doing the need to consult and involve riders' representatives and
other interested parties is recognized as both desirable and necessary.
- The riders' organizations, in consultation with other interested
parties, undertake to develop a social awareness program. The purpose
of which will be to inform riders of the need to ensure that their
motorcycles and the way in which they ride them, do not significantly
impinge upon the freedoms and quality of life of other citizens.
- In support of this objective it is recognized that the extent to
which noise is a factor in ensuring the safety of motorcyclists and
other road users, needs to be further investigated. Accordingly funding
for research into this question will be sought by the Parties to the
- It is accepted that for the reasonable noise limit values and the
certification of replacement parts procedures to be fully effective,
the development of new measures to ensure the fair and effective enforcement
of them is needed. Accordingly the support of Federal agencies and
legislators will be sought to provide the resources to enable fair
and effective enforcement means and methods to be developed.

- Hard, flat surface required; no obstacles within 30 m radius of
- 80/82 dB(A) limit
SAE J1287 Jul98 Stationary Sound Test Procedure
- In-use noise measurement for off-highway motorcycles and ATVs
