Acoustical Assurance Period – obfuscation

First of all, the obfuscation/misinterpretation by the Motorcycle Rights Organizations relevant to the U.S. EPA/Code of Federal Regulation’s “Acoustical Assurance Period” (AAP) located at Title 40 → Chapter I → Subchapter G → Part 205 → Subpart D → §205.152

See: https://www.ecfr.gov/cgi-bin/text-idx?SID=d2d0ed3881013fdb0749ea2d54013cf7&mc=true&node=se40.27.205_1152&rgn=div8

(3) Street motorcycles must be designed, built and equipped so that, when properly maintained and used, they will not produce noise emissions in excess of the levels specified in paragraph (a)(1) of this section, for an Acoustical Assurance Period of one year or a distance of 6000 km (3730 mi) after the time of sale to the ultimate purchaser, whichever occurs first.

Don’t believe the obfuscation: The Motorcycle Rights Organization’s will attempt to defer or negate LOUD Biker culpability for illegally removing the OEM – Factory-installed motorcycle muffler and replacing same with an illegally loud NOT FOR ROAD USE muffler by obfuscating, misinterpreting the meaning and intent of the Acoustical Assurance Period.

Loud Biker advocates will tell you that the stock/OEM, quiet, factory-installed muffler is only “good” for 3730 miles or one-year from the time of retail/sale.  NOT TRUE – the original, U.S. EPA approved, factory-installed muffler is intended to remain in compliance for the LIFE OF THE MOTORCYCLE according to the author of the AAP, Kenneth Feith (Former EPA Employee).  The AAP is simply a “warranty period” required by the EPA from the manufacturer to the consumer to ensure the acoustical integrity of the factory-installed muffler…for more information, please see:

ACOUSTICAL ASSURANCE PERIOD (Excerpts from article)

“The regulation includes an Acoustical Assurance Period (AAP), which specifies a relatively short period during which a motorcycle’s noise abatement elements must be in compliance with the federal regulation during street usage.  Some have interpreted this to mean that, once the AAP has expired, the regulation no longer applies.  This wording of the regulation needs clarification that noise emissions limits apply for the life of the motorcycle.”

 “The EPA should make clear in the regulatory requirements that the tampering provisions apply to all persons for the life of the motorcycle.  In other words, noise limits for owners/operators remain in effect for the life of the motorcycle and do not expire at the end of the AAP.”
