The picture
Across 1,700 MOT tests, the Tiger 900 Gt Pro returns 94.6% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is uneven braking force. Stiff steering bearings and a non-functioning shock absorber round out the top three. Average tested mileage sits at 9,877, 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.
