COMMISSION DIRECTIVE 2002/41/EC

of 17 May 2002

adapting to technical progress Directive 95/1/EC of the European Parliament and of the Council on
the maximum design speed, maximum torque and maximum net engine power of two- or three-
wheel motor vehicles

THE COMMISSION OF THE EUROPEAN COMMUNITIES,

Article 2

Having regard to the Treaty establishing the European
Community,

Having regard to Council Directive 92/61/EEC of 30 June 1992
relating to the type-approval of two- or three-wheel motor
vehicles (1), as last amended by European Parliament and
Council Directive 2000/7/EC (2) and in particular Article 16
thereof,

Having regard to Directive 95/1/EC of the European Parliament
and of the Council of 2 February 1995 on the maximum
design speed, maximum torque and maximum net engine
power of two- or three-wheel motor vehicles (3), and in partic-
ular Article 4 thereof,

Whereas:

(1)

(2)

(3)

(4)

(5)

Directive 95/1/EC is one of the separate directives under
the Community type-approval procedure introduced by
Directive 92/61/EEC. The provisions of Directive 92/
61/EEC relating to systems, components and separate
technical units for vehicles therefore apply to Directive
95/1/EC.

In order to enable the full type-approval system to func-
tion properly, it is necessary to clarify or supplement
certain requirements of Directive 95/1/EC.

To that end, it is necessary to specify the values to be
to ensure the consistent
entered in the test report
application of Directive 95/1/EC in the case of mopeds,
motorcycles and tricycles with spark-ignition engines
and two- or three-wheel motor vehicles with compres-
sion-ignition engines.

Directive 95/1/EC should therefore be amended accord-
ingly.

The measures provided for in this Directive are in
the Committee for
accordance with the opinion of
Adaptation to Technical Progress set up under Article 13
of Council Directive 70/156/EEC (4), as last amended by
Commission Directive 2001/116/EC (5),

1. With effect from 1 July 2003, Member States may not,
on grounds relating to the maximum design speed, maximum
torque and maximum net engine power:
— refuse to grant EC type-approval for a type of two- or

three-wheel motor vehicle, or

— prohibit the registration, sale or entry into service of two-

or three-wheel motor vehicles;

if the maximum design speed, maximum torque and maximum
net engine power of the vehicles comply with the requirements
of Directive 95/1/EC, as amended by this Directive.

2. With effect from 1 January 2004, Member States shall
refuse to grant EC type-approval for any new type of two- or
relating to the
three-wheel motor vehicle on grounds
maximum design speed, maximum torque and maximum net
engine power if the requirements of Directive 95/1/EC, as
amended by this Directive, are not fulfilled.

Article 3

1. Member States shall bring into force the laws, regulations
and administrative provisions necessary to comply with this
Directive by 30 June 2003 at the latest. They shall forthwith
inform the Commission thereof.

those provisions,

When Member States adopt
they shall
contain a reference to this Directive or be accompanied by
such a reference on the occasion of their official publication.
Member States shall determine how such reference is to be
made.

2. Member States shall communicate to the Commission the
main provisions of national law that they adopt in the field
covered by this Directive.

Article 4

This Directive shall enter into force on the 20th day following
its publication in the Official Journal of the European Communities.

This Directive is addressed to the Member States.

Article 5

HAS ADOPTED THIS DIRECTIVE:

Done at Brussels, 17 May 2002.

ANNEX

The Annexes to Directive 95/1/EC are amended as follows:

1. Annex I is amended as follows:

(a) in point 5 the second line is replaced by the following:

‘Atmospheric pressure: 97 ± 10 kPa.’

(b) in point 5 the fifth line is replaced by the following:

‘Average wind speed, measured 1 m above the ground: < 3 m/s, permitting gusts < 5 m/s.’

2. Annex II is amended as follows:

(a) in Appendix 1, point 3.1.2, Table 1, the first sentence of note (3) is replaced by the following:

‘The radiator, fan, fan nozzle, water pump and thermostat must, on the test bench, occupy as far as possible the
same position relative to each other as if they were on the vehicle. If the radiator, fan, fan nozzle, water pump
and/or thermostat have a position on the test bench which is different from that on the vehicle, the position on the
test bench shall be described and noted on the test report.’

(b) in Appendix 1, point 4.1 is replaced by the following:

‘4.1.

and α

2

Factors by which the torque and power measured are to be multiplied in order to determine the torque
and power of an engine, taking account of the efficiency of the transmission (factor α

tests and in order to bring that torque and that power within the reference atmospheric conditions
specified in 4.2.1 (factor α

).
