MOT Test Part 8:

8.1.1. Exhaust noise
If possible, you should assess the exhaust noise by revving the engine to approximately half the maximum engine speed. The engine should be warm before you carry out this check.
It is not possible to rev the engine on twist and go type motorcycles.
The exhaust system and silencer should be in such condition, or of such a type, that the noise emitted from the motorcycle is
not clearly unreasonably above the level expected from a similar motorcycle with a standard silencer in average condition.
Defect
Category(a) Exhaust noise levels in excess of those permitted - Major
