Motorcycle Seat Conversions: Maintaining Safety and Legal Compliance at Ausmec Mobile RWC and Mechanics

At Ausmec Mobile RWC and Mechanics, we understand that some riders may prefer a single-seat setup for their motorcycle. However, it's crucial to ensure any seat conversions comply with Queensland Department of Transport and Main Roads (TMR) regulations ( to maintain safety, legal compliance, and proper insurance coverage.

Here's a breakdown of key TMR guidelines for motorcycle seat conversions:

Converting from Dual Seat to Single Seat:

  • Reduced Insurance Premiums: You may be eligible for lower Compulsory Third Party (CTP) insurance premiums with a single-seat configuration.
  • Converting Back for Passengers: If you plan to carry a passenger (pillion) in the future, you must convert the seat back to a dual configuration.
  • Registration and Insurance Updates: It's essential to update your CTP category and motorcycle registration details to reflect the current single-seat configuration. Failure to do so could result in a lack of insurance coverage for you and your passenger in case of an accident, and potential penalties.

Conversion Requirements:

  • Irreversible Modifications: TMR discourages easily reversible seat conversions. A compliant conversion should involve permanent modifications.
  • Seat Length Reduction: The modified single seat must be 500mm or less in length. Simply using a removable seat cowl or cover is not sufficient.
  • Pillion Footpeg Removal and Deactivation: The pillion footpegs must be removed, and their mounting points disabled by removing brackets and drilling out threaded holes.

Converting from Single Seat to Dual Seat:

  • Rider and Pillion Accommodation: The converted dual seat must provide adequate seating space for both the rider and a passenger.
  • Footrests for Both: Both the rider and pillion must have proper footrests for a safe and comfortable ride.
