Motorcycle Emissions
Motorcycles to become more environmentally friendlyBy
2006, exhaust emissions from new motorcycles will be
the same as for cars. This is the main objective of
the new European legislation seeking to reduce motorcycle
emissions over the next four years. FEMA will be part
of the Working Group which aims at developing the technical
details in connection with the new legislation.
The objective of the new EU-legislation will be achieved
in two steps. The first one reducing of 60% the Carbon
monoxide (CO) and Hydrocarbons (HC) emissions of new
four-stroke bikes produced from 1st April 2003. The
second one, entering into force on 1st January 2006,
will apply a further 50% reduction compared to the 2003
limits. 2-stroke engines will see their emissions output
reduce by 30% for CO and 70% for HC. Motorcycle have
a quite low level of oxides of nitrogen (NOx) and limits
will remain the same for 2003 giving the time for the
Industry to achieve more drastic NOx measures for 2006.
The technical requirements set for new bikes produced
from 2006 can be achieved quite easily with current
technologies, such as fuel injection systems and catalysers.
To give an example, the 1000cc Suzuki V-Strom produced
in 2002, equipped with a regulated catalyser, oxygen
sensor and fuel injection, complies with 2003 emissions
limits and is very close to the 2006 ones. In terms
of costs, the price of this bike is about the same as
its competition (Triumph Tiger, Honda Varadero, BMW
R1150GS, Aprilia CapoNord, Yamaha TDM900. (Source: Motorrad
- March 2002).
In parallel with the implementation of these new emissions
requirements, a new dedicated test cycle for motorcycles
will be introduced. The World Motorcycle Test Cycle
(WMTC), as it is officially called, will have its own
emission limits but these will be set in correlation
with the ones presently set in the legislation, to ensure
a similar environmental performance. The new test will
for a period run in parallel with the present modified
car test cycle, giving temporarily the manufacturers
a choice between two type-approval procedures.
In use conformity checks and durability requirements
will also be introduced from 2006, to control the conformity
of original emission output of vehicles under normal
conditions of use, and to guarantee the environmental
performance during the first 30.000 km traveled. FEMA
will participate in a working group set up by the European
Commission to investigate the practical implementation
of these measures, and will make sure that riders will
not bear the costs of such measures. The European Union
will at a later stage introduce requirements for the
measurement of Carbon dioxide (CO2), motorcycles will
be included in this strategy.
Fiscal measures have been agreed to encourage the fitting
of devices making older bikes "cleaner" and
new ones pre-complying with the emission limits set
for 2006. However, Member States can still include a
"pollutant factor" in their national road
traffic taxes and penalise older vehicles. FEMA member
organisations will continue to promote the real benefits
of Powered Two-Wheelers for urban mobility, and try
to avoid discriminatory measures being introduced in
their countries.
