Working Party Working Motorcycle Noise Motorcycle Noise Uniform Provisions Concerning the Approval of Motor Cycles with regard to Noise Under the current 04 series of amendments to UN Regulation No. 41, the engine speed should be measured during all tests in Annex 3 and Annex 7 (Additional sound emission provisions - ASEP). However, IMMA has found that there is very little difference between the measured and the calculated engine speed for a manual transmission (MT) vehicle (Annex, figure 1) and no impact on the test result (Annex, figure 2). Therefore, this proposal would introduce a calculated engine speed for MT vehicles and for continuously variable transmission (CVT)/automatic transmission (AT) with locked gear mechanism into UN Regulation No. 41. 19 Nov 2014
