You asked: “Please confirm the make and model of equipment required to test motorcycles for ULEZ exemption, specifically testing NOx output to produce a Certificate of Conformity.”
The testing that would be required for motorcycles is the type-approval ‘type 1’ emissions test. This test must be performed on a dynamometer capable of being adjusted for appropriate road-load coefficients and with a driver aid capable of displaying the appropriate velocity/time co-ordinates for the legislative drive cycle for each class of motorcycle. Emissions analysis must be by a minimum of a 5 gas analyser specified to measure NOx over the required drive cycle, whilst taking account of total gas volume over the same cycle, and producing a single value in grammes/km. Emissions testing is to be carried out in accordance with the regulation ECE/TRANS/180/Add2
