           1.3.3.5 During this conditioning procedure, at the request of the manufacturer, the engine and the silencer may be cooled in order that the temperature recorded at a point not more than 100 mm from the exhaust gas outlet does not exceed that measured when the motor cycle is running at 110 km/h or 75% S in top gear. The engine and/or motor cycle speeds are determined to within +/- 3%.
