No L 24/42 Official Journal of the European Communities 27. 1. 87 COUNCIL DIRECTIVE of 18 December 1986 amending Directive 78/1015/EEC on the approximation of the laws of the Member States relating to the permissible sound level and exhaust system of motorcycles (87/56/EEC) THE COUNCIL OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Economic Community, and in particular Article 100 thereof, Having regard to the proposal from the Commission " Having regard to the opinion of the European Parli- ament (%), Having regard to the opinion of the Economic and Social Committee (%), Whereas Annex I to Directive 78/1015/EEC (") defines limits for the sound level of motorcycles ; whereas Article 8 of that Directive states that the Council shall, on a proposal from the Commission, decide on a reduction in the maximum permissible sound levels provided for in the said Annex I; Whereas, when Directive 78/1015/EEC was adopted, emphasis was given to the fact that it costituted a step towards the improvement of the environment, that the technical development of less noisy motorcycles should be further encouraged that the limit values prescribed at the time should be reduced to approximately 80 dB (A) before 1985, particularly in the case of more powerful motorcycles, and that the levels to be fixed should take account of the technical resources which would be avai- lable at that date; Whereas the protection of the population in urban envi- ronments against acoustic nuisance calls for suitable measures to reduce the sound level of motorcycles; whereas such a reduction should be made possible by the technical progress achieved or to be promoted in the manufacture of these types of vehicle; Whereas, to this end, Directive 78/1015/EEC should be amended in order to make the prescribed method of measurement more representative of the conditions of actual use of motorcycles in urban traffic, to reduce the number of categories of motorcycle in view of the diffe- rent methodology and to reduce the differences in the treatment of these categores; whereas the definition of sound level limit values for each of these new categories of motorcycle will lead to an effective reduction in the ) OJ No C 263, 2. 10. 1984, p. 5. %) O] No C 94, 15. 4. 1985, p. 142. ) O No C 104, 25. 4, 1985, p. 3.

Article 2 1.

Two years after the dates referred to in paragraph 2, Member States may prohibit the initial entry into service of motorcycles the sound level and exhaust system of which do not comply with the said Directive.
