2006 Supermoto USA Noise Policy

If the choice is to run quiet, or not run at all... everyone is going to have to run quiet.

So, here's is what is going to happen:

1. Your exhaust pipe will be inspected in tech.

A. The only pipes that will pass tech without additional inspection are:
-- LeoVince FIM
-- CRD Offroad Abs Performance 2
-- FMF Q series
-- 2 stroke pipes
-- Stock pipe on any model *
-- pipes on any 4 stroke < 200 cc *

B. Pipes not listed in a. will be inspected for the following:
-- sound reducing end cap/cork *
-- additional sound reducing baffle plates (for supertrapp style exhaust)
If your bike has a cork/ your pipe mount screws will be taped with a metal tape. Any modification/removal of the cork after tech will be grounds for disqualification and removal of any points earned.

C. bikes not meeting A or B will not be allowed to participate in the event.

* is not a guarantee of passing sound test. We reserve the right to black flag any bike at any time for excessive noise.
 

2. We will be performing sound testing during practice and race sessions.

If you are over 98db at 100 feet at any time, you will be given one opportunity to resolve it before being excluded. This means we will black flag you from any practice or race session where you are found to be over the db limit.

You will not be allowed to reenter the track until the issue is resolved. Your bike must pass off track sound tech before you can reenter the track. 

There will be NO REFUNDS for those who have entered the races and or practice and are unable to meet sound requirements.
 

3. We will be providing a separate sound tech for those who are concerned they may not pass or those who have failed.

Testing away from the track surface will be conducted to ensure compliance.

Statement:
Our official limit is 98db at 100 feet WOT. This is the last gasp measurement that we will have to do. We want you to voluntarily comply with this; the absolute last thing we want to do is to send riders home.

We know all about the forestry service test and it's standards, (3', 45 degrees, 1/3 throttle). That test has very little impact on the noise that our bikes make (since so much time is spent above 1/3 throttle).

There are some pipes that are the very edge of the 98 db limit and you guys know who you are (some akro's, CHM's, FMF's etc). We want to encourage you guys to at a MINIMUM go back to your stock pipes.

Everybody has known about this for some time, so it should not be a surprise.
