(3) Under Article 5 of Directive 97/24/EC, the Commission is required to submit, within 24 months from the date of adoption of the said Directive, to the European Parliament and the Council, a proposal prepared on the basis of research and an assessment of the costs and benefits deriving from the application of tightened-up limit values and laying down a subsequent stage during which measures will be adopted aimed at further tightening of the limit values for pollutants of the vehicles concerned; such action is limited to motorcycles, since a subsequent stage entailing tighter limit values for mopeds, to be applied from 17 June 2002, is already provided for in Directive 97/24/EC.
