ABSTRACT
The Euro 5 limits for L-category vehicles are applicable since 2020 and for this reason there is lack of studies examining the emissions of this category. In this study we tested a 1000 cm3 Euro 5 motorcycle over the World Harmonised Motorcycle Test Cycle (WMTC). The gaseous pollutants were approximately half of their respective limits. The cold start (first 2 minutes) contributed to the majority of the emissions. The solid particle number emissions were also 6.5 times below the limit for passenger cars, but the particles not counted with the current methodology were around 2 times higher. High concentrations of volatiles were emitted at the high speed part of the cycle.
