ADMINS: Forum Build Off Question

[fourtyounce]

I didn't see how to contact an admin, so here's a question from KTM Talk. What method will be used to measure the bikes noise level(db)?

I am sure Okie will see this soon

I am not sure that it was specified

 

[Rich Rohrich]

Using the MIC published RPM numbers for sound testing and the SAE J-1287 test procedure,
MX bikes must be below 99db
Off-road bikes must have a Spark Arrestor and be below 96db

Thank you.
