- Start with missing - it accounts for 45.3% of failed tests on this model.
- Then check does not conform to the specified requirements and not working, the next two most common reasons.
- The most common advisory is noise is clearly in excess of that emitted by a similar motorcycle fitted with a standard silencer in average condition (24.2% of all tests) - not a failure, but money you will spend sooner or later.
