6. SPECIFICATIONS

           6.1. General specifications

           6.1.1. The following information shall be provided on the motor cycle in an easily accessible but not necessarily immediately visible location:
           (a) the manufacturer's name
             (b) the value in dB(A) recorded during the stationary test required by paragraph 6.2.1.1.
             (c) the engine speed at 3/4 S if S does not exceed 5000 min-1, or at 1/2 S if S exceeds 5000 min-1

6.2. Specifications regarding sound levels

           6.2.1. Methods of measurement

           6.2.1.1. The noise made by the motor cycle type submitted for approval shall be measured by the two methods described in annex 3 to this Regulation for the motor cycle in motion and for the motor cycle when stationary.[19]/

           6.2.1.2. The two values measured in accordance with the provisions of paragraph 6.2.1.1. above shall be entered in the test report and on a form conforming to the model in annex 1 to this Regulation.

           6.2.1.3. The sound level measured by the method described in annex 3, paragraph 3.1. to this Regulation when the motor cycle is in motion shall not exceed the limits prescribed (for new motor cycles and new exhaust or silencing systems) in annex 6 to this Regulation for the category to which the motor cycle belongs.

           6.3. Additional specifications regarding exhaust or silencing systems or components filled with fibrous material.

           6.3.1. If the motor cycle is fitted with a device designed to reduce the exhaust noise (silencer), the requirements of annex 5 shall apply. If the inlet of the engine is fitted with an air filter and/or an intake-noise absorber which is (are) necessary in order to ensure compliance with the permissible sound level, the filter and/or absorber shall be considered to be part of the silencer, and the requirements of annex 5 shall also apply to them.

           6.3.2. A diagram and a cross-sectional drawing indicating the dimensions of the exhaust system shall be appended to the certificate referred to in annex 1.
