2013 Yamaha YBR 125 0.1L Petrol · RO13 ABU

The 2013 Yamaha YBR 125 demonstrates a deteriorating maintenance trend, as evidenced by its failed MOT on 31 May 2023 at 27,106 miles. The most recent test revealed multiple critical faults including an exhaust gas leak, front tyre worn to the legal limit, restricted rear brake pivot movement, a continuously illuminated stop lamp, and an insecure chain guard. This failure follows a pattern of recurring mechanical issues, with the 2021 test also recording a failed status due to a non-functioning rear position lamp and worn drive chain, indicating inconsistent upkeep over time. The recorded mileage of 27,106 miles over 13 years equates to an average of approximately 2,085 miles per annum, which is notably low for the vehicle's age. Mileage progression shows steady accumulation from 8,665 miles in June 2016 to 27,106 miles in May 2023, with no significant gaps in testing intervals. The 2020 test at 17,868 miles recorded no defects, suggesting a period of acceptable condition, though subsequent failures indicate emerging issues. The low annual mileage may contribute to component degradation through infrequent use, potentially leading to seized or binding mechanisms rather than wear from regular operation. Prospective buyers should conduct a thorough inspection focusing on the exhaust system for leaks, particularly around joints and the manifold, and verify front tyre tread depth against legal minimums. The rear brake assembly requires careful examination of the pivot point for smooth operation and the brake light switch functionality to prevent it remaining engaged. The chain guard must be securely fastened, and the drive chain tension and wear should be assessed, as both were flagged in previous tests. Additionally, the rear wheel bearing play noted in 2022 and 2021 warrants investigation for potential bearing failure or hub damage. The fuel cap sealing washer and footrest rubbers from the 2016 failure may still present issues if original components remain in place.
