What to check before the MOT

Built from this model's own failure record, not general advice.

  • Start with not working - it accounts for 41.8% of failed tests on this model.
  • Then check missing and has a serious fluid leak, 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 (10.6% of all tests) - not a failure, but money you will spend sooner or later.
  • Average recorded mileage at test is 26,019 miles, which is the number to compare any advert against.

6-10 years 83.04% 395
11-15 years 82.82% 163
