2021 Yamaha MT 125 (mtn 125-A) 0.1L Petrol · ST21 ABO

The vehicle most recently passed its MOT on 17 June 2025, indicating a generally stable mechanical condition. With only a single advisory noted regarding the rear tyre tread, the overall maintenance trend appears consistent, suggesting the motorcycle has been kept in a roadworthy state without a history of recurring structural or mechanical failures. The recorded mileage of 10,925 miles over approximately five years is notably low, averaging roughly 2,185 miles per annum. While this suggests minimal wear on the engine internals, gearbox, and primary drivetrain, such low usage often indicates periods of inactivity. This usage profile shifts the inspection focus from wear-and-tear degradation to time-based deterioration, where components may fail due to standing rather than active use. Regarding the specific MOT advisory, the rear tyre is approaching the legal limit and will require replacement in the near future to ensure safe grip and braking performance. During a physical inspection, check the tyre for squaring, where the centre tread wears faster than the edges, and examine the sidewalls for perishing or hairline cracking resulting from age and UV exposure. Ensure the front tyre is similarly inspected for age-related hardening of the rubber compound, which can significantly reduce cornering traction. Given the low annual mileage, particular attention must be paid to the effects of standing. Inspect the brake discs for surface corrosion and check for binding calipers that may have seized during periods of inactivity. The 12V battery should be tested for voltage stability, as infrequent charging cycles often lead to premature failure. Finally, verify the service history to ensure that engine oil and brake fluids have been changed according to the manufacturer's calendar intervals rather than mileage alone, as these fluids degrade chemically over time regardless of distance travelled.
