Regulation No. 41 (Noise emissions of motorcycles)

Paragraph 6.3., amend to read:

"6.3.1. The motor cycle manufacturer shall not intentionally alter, adjust, or introduce

any device or procedure solely for the purpose of fulfilling the noise emission

requirements of this Regulation, which will not be operational during typical

on-road operation.

The vehicle type to be approved shall meet the requirements of Annex 7 to this

Regulation. If the motor cycle has user selectable software programs or modes

which affect the sound emission of the vehicle, all these modes shall be in

compliance with the requirements in Annex 7. Testing shall be based on the

worst-case scenario.

In the application for type approval or for modification or extension of a type

approval the manufacturer shall provide a statement in accordance with Annex

8 that the vehicle type to be approved complies with the requirements of

paragraph 6.3.1. of this Regulation.

The test results obtained in accordance with the provisions of paragraph 6.3.2.

above shall be entered in the test report and on a form conforming to the model

in Annex 1 to this Regulation."

by more than 1.0 dB(A) the limits given in paragraph 2.6. of Annex 7."
