This agenda item relates to UN R41 Motorcycle Noise.

GRBP will consider a revised proposal submitted by the expert from IMMA which aims to minimize a proliferation of approval numbers (ECE/TRANS/WP.29/GRBP/2019/25/Rev.1).

GRBP will also recall that, at the previous session, it adopted ECE/TRANS/WP.29/GRBP/2019/24 but agreed to postpone its submission to WP.29 and the Administrative Committee (AC.1), awaiting other amendment proposals.

GRBP will consider the text by the expert from IMMA to amend UN Regulation No. 41-04
