2007 ATVA MX Sound Testing
Procedures for Pro & Amateur Racers
Morgantown, WV (3/5/2007)
– The ATV Promoters Group (ATVPG), in cooperation
with AMA Racing and ATVA, announced that Pro ATV motocross
racers will need to comply with slightly stricter
sound-limit requirements now that they are competing
under the AMA Pro ATV Racing banner.
The decibel limit for the 2007 racing
season is 99-decibels. While racing in ATVA-sanctioned
events last year, pro riders were required to comply
with a 102-decibel limit as measured using the Society
of Automotive Engineers J-1287 test standard. The
test is performed with a sound meter on the "A"
scale measured 20 inches from the exhaust, with the
engine running at a designated rpm. For example, a
450cc quadcycle tested at 3,750 rpm.
AMA Pro ATV racing will use the same
test on competitors, but instead of measuring machines
at a designated rpm, the test rpm will be determined
by the formula of 306,000 divided by the engine's
stroke. What this means is that the pro machines will
be tested at a slightly higher rpm than in previous
seasons.
Amateur racers will still be tested
under the old procedures.
Another important distinction for this
year's pro competitors is that the race manager can
require post-race sound testing. In that event, the
AMA technical inspector will conduct the test, and
the machine must meet a sound limit of 101 decibels.
Given the stricter requirements and
the proximity of the first round of the series - the
ATV Southern Nationals at Mill Creek Motocross Park
in Pell City, Alabama, March 10-11 - Pro riders will
be permitted a grace range within 3 decibels of the
maximum limit of 99 decibels for the first four rounds
of the series.
Thereafter, Pro riders must meet the
99-decibel limit by the fifth round - the Birch Creek
National at Birch Creek in Danville, Virginia, April
28-29.
The 12-round Series revs up on March
10-11 with the ATV Southern Nationals at Mill Creek
MX Park, located in Pell City, Alabama, and concludes
August 11-12 with the Loretta Lynn's Dirt Days, in
Hurricane Mills, Tennessee.
