Category A1 motorcycle without sidecar, with a power rating not exceeding 11 kW and with a power to weight ratio not exceeding 0,1 kW/kg, and capable of a speed of at least 90 km/h.

The following paragraphs shall be inserted after paragraph 3:" 3a. TYPE-APPROVAL OF STAGE IIIA ENGINES (ENGINE CATEGORIES H, I, J and K) Member States shall refuse to grant type-approval for the following engine types or families and to issue the document as described in AnnexVII, and shall refuse to grant any other type-approval for non-road mobile machinery in which an engine, not already placed on the market, is installed: – H: after 30 June 2005 for engines – other than constant speed engines – of a power output: 130 kW ≤ P ≤ 560 kW, – I: after 31 December 2005 for engines – other than constant speed engines – of a power output: 75 k ...[+++]W ≤ P

a C.I. engine having a net power in accordance with section 2.4 that is higher than or equal to 19 kW but not more than 560 kW and that is operated under intermittent speed rather than a single constant speed; or

If the AFM does not contain a one-engine-inoperative cruising speed, the speed to be used for calculation must be that which is achieved with the remaining engine(s) set at maximum continuous power.

a C.I. engine having a net power in accordance with section 2.4 that is higher than 18 kW but not more than 560 kW ( ) and that is operated under intermittent speed rather than a single constant speed.

It should, however, be recalled that a few years ago, the Commission proposed, for reasons of safety, to limit the engine power of large motorcycles through its proposal for a Directive on the maximum design speed, maximum torque and maximum net engine power of two or three wheel motor vehicles.
