Proposal to amend Annex 7, paragraph 3.1, to add provisions allowing discard of test runs when additional operating conditions lead to riding conditions not expected to occur in real traffic such as front wheel lift up, apparent wheel spin, chain slap, or engine lugging, and amend paragraph 3.2.2 to specify that if unusual riding conditions occur during testing, the test shall be performed in the next higher gear and maximum vehicle speed shall be reached at line BB’ instead, thereby ensuring consistency with the 05 and 06 series of UN Regulation No. 41.
