Four state-of-the-art >500 cc Euro 3 and one 150 cc Indian specification motorcycles were selected and evaluated over the Euro 3 and world harmonized WMTC test cycles for regulated pollutants and particles. The objectives of the work were to examine the correlation between emissions on the WMTC and Euro 3 cycles, to compare those results with previous work completed before the European WMTC limits were set, to examine particulate emissions, and to then evaluate the durability of one machine.The correlation between Euro 3 and WMTC emissions results was used to extrapolate the appropriate level of WMTC limit values from the emissions limits on the Euro 3 test cycle. These WMTC extrapolated emissions limits were in line with the previous AECC motorcycle test program conducted in 2004 on Euro 2 motorcycles and also confirmed the appropriate level of the WMTC Euro 3 limits set in European Directive 2006/72/EC amending 97/24/EC.As a result of these 2004 and 2008 test campaigns, two of the selected motorcycles were tested in both Euro 2 and Euro 3 versions, allowing for comparison of the emissions performance improvement realized by the motorcycle manufacturers.Even though Euro 5 SI passenger car gaseous emissions limits are much lower than Euro 3 motorcycle levels, some of the tested bikes almost met them. All the bikes met the Euro 5 diesel passenger car particle number limit, after recalculation to give a NEDC equivalent value, despite sporadic rich operation giving higher particle numbers.A further phase of work evaluated durability performance of a selected Euro 3 motorcycle. The durability exercise was cut short as both CO and NOx emissions exceeded the prescribed Euro 3 limits after only a couple of thousands of kilometers accumulated on a chassis dynamometer and had reached double the limit values well before the end of the durability period.
