The Amendment 4 to GTR2 was published – A major step forward for harmonisation of motorcycle emission standards

One of the key updates in this Amendment to GTR No. 2 was the expansion of the scope providing possibility for two-wheeled vehicles with a design speed under 50 km/h and with an engine capacity under 50 cc to be tested with the GTR 2 test cycle profile (WMTC), with a 10 minutes cold engine phase followed by a 10 minutes warm engine phase. The test speeds would be capped to the maximum design speeds of these vehicles.
