Keeping it Quiet: Exhaust Regulations for Motorcycles at Ausmec Mobile RWC and Mechanics

At Ausmec Mobile RWC and Mechanics, we understand that motorcycles are known for their exhilarating sound. However, it's crucial to ensure your motorcycle's exhaust system complies with Queensland Department of Transport and Main Roads (TMR) regulations ( to maintain noise limits and responsible operation. Here's a breakdown of key TMR guidelines for motorcycle exhaust systems:

General Regulations:

  • All motorcycles in Queensland fall under Schedule 1, Part 9 of the Transport Operations (Road Use Management—Vehicle Standards and Safety) Regulation 2021. This regulation outlines noise emission standards for motorcycles.

Exhaust Marking and Replacement:

  • Motorcycles manufactured from July 1, 1988, onward have their silencing system components (including mufflers) marked with the manufacturer's name or trademark. Any replacement parts for the silencing system must also display this information for easy identification.

ADR 83/00 Compliance:

  • Motorcycles manufactured from January 1, 2006, must comply with Australian Design Rule (ADR) 83/00. This rule sets specific noise emission limits for motorcycles. These motorcycles also have a "stationary signature" noise limit, which refers to the maximum allowable noise level when the motorcycle is stationary under specific testing conditions.

Noise Testing Procedures:

  • Noise testing for motorcycles follows the National Transport Commission's stationary noise test procedure for in-service motor vehicles. This ensures standardized testing methods for noise compliance.

Exhaust Modifications and Noise Levels:

  • It's essential to avoid replacing or modifying your motorcycle's exhaust system if it's likely to increase noise output beyond the limits of the unmodified system in good working condition. Excessive noise from your motorcycle can not only be a nuisance but can also lead to fines and penalties.
