COUNCIL DIRECTIVE of 13 March 1989 amending Directive 78/1015/EEC on the approximation of the laws of the Member States on the permissible sound level and exhaust systems of motorcycles (89/235/EEC)

THE COUNCIL OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Economic Community, and in particular Article 100a thereof,

Having regard to the proposal from the Commission (1),

In cooperation with the European Parliament (2),

Having regard to the opinion of the Economic and Social Committee (3),

Whereas it is important to adopt measures with the aim of progressively establishing the internal market over a period expiring on 31 December 1992; whereas the internal market shall comprise an area without internal frontiers in which the free movement of goods, persons, services and capital is ensured;

Whereas Directive 78/1015/EEC (4), as last amended by Directive 87/56/EEC (5), lays down limits for the sound level of motorcycles and provisions governing exhaust systems fitted as original equipment to motorcycles;

Whereas replacement exhaust systems very frequently differ from original equipment; whereas this situation therefore

has, among other things, adverse effects on the sound emissions of motorcycles; whereas an EEC type-approval procedure for such replacement devices, making it possible to

establish that a type of device meets the technical requirements and checks laid down at Community level, is likely to be an adequate means of reducing the sound level of motorcycles in use and of affording the population additional protection against noise nuisances caused by such vehicles;

Whereas, to that end, Directive 78/1015/EEC should be amended by including provisions on exhaust systems as separate technical units to be marketed and used as replacement parts, so that such equipment may be regulated by Community requirements for ensuring effective protection against noise nuisances,

HAS ADOPTED THIS DIRECTIVE:

Article 1 Directive 78/1015/EEC is hereby amended as follows:

1. Article 2 is replaced by the following:
