Loud pipes may or may not save lives*,
but they will surely cost money this summer in one Alberta city.
The city of Edmonton has moved to
require motorcycles to keep within noise limits as specified by the new SAE J2825 sound emission tests for motorcycles.
Any motorcycles that exceeds the test limits will be subject to a fine of $250.
Edmonton police have acquired eight
sound meters, and will start using them on some city streets next
Police said motorcycles across Canada
were tested for adherence to the sound limit while the Edmonton law
was being written; about one in six failed the test, but all had
modified exhaust systems. They said stock pipes had no trouble
Edmonton’s city council still needs to
pass the bylaw, but that is expected.
ABOUT THE SAE J2825 TEST
It’s a 2 stage test;
First an idle test, which can be
as a screening test where the sound level of any model tested must not
exceed 92dbA. Following the screening test a mid
test is conducted, motorcycles are separated into 2 classes:
- 2000 rpm for less than 3 cylinders
and more than 4 cylinder, limit is 96 dbA
- 5000 rpm for 3 or 4 cylinders,
is 100 dbA
(test procedure calls for 75% of
rpm or 2000/5000 rpm, whichever is less)
