Cbr125r: a below-average pass rate worth digging into

Across 922 MOT tests, the Cbr125r returns 68.1% first-time pass — well below the UK fleet average. The single most-logged Major fail is a non-functioning shock absorber. A binding brake and tyre tread under the limit round out the top three. Average tested mileage sits at 22,215, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.
