ISO 6460-2:2014 defines test cycles for measurement for the gaseous exhaust emissions from motorcycles, as well as for determining the fuel consumption of motorcycles as defined in ISO 3833, equipped with a spark ignition engine (four-stroke engine, two-stroke engine, or rotary piston engine) or a compression ignition engine. The test cycle 1 is equivalent to the test cycle specified in the European Union Commission Directive 2003/77/EC[6] and the test cycle 2 is equivalent to the test cycle specified in global technical regulations No.2 (WMTC), United Nations Economic Commission for Europe, ECE/TRANS/180/Add.2[9]. A selection of other test cycles adopted or to be adopted by several countries is described in Annex C for information purpose.
