2017 Yamaha YS 125 0.1L Petrol · HS17 ELX

The most recent MOT test on 2025-05-06 confirms the vehicle remains roadworthy with no defects recorded at 4,601 miles. The consistent pass history since 2023—with no advisories or failures—suggests the Yamaha YS 125 has been maintained at a basic level, though the lack of defects does not imply thorough servicing. The final pass in May 2025 was just 14 months ago, which is acceptable given the low mileage, though a test every 12 months is the DVSA’s minimum requirement. No recurring issues indicate a worsening trend, but the absence of advisory notes means critical components like suspension bushes, coil springs, or binding calipers were not specifically inspected beyond a pass/fail threshold. The recorded mileage of 4,601 miles over nearly nine years—approximately 511 miles annually—is unusually low for a vehicle of this age. This pattern suggests the bike has spent extended periods stationary, which can accelerate wear on rubber components (tyres, seals) and lead to corrosion in exposed metal parts. The 2022 failure at 2,697 miles, though without recorded defects, is anomalous given the subsequent passes at identical mileage in 2023. This inconsistency may imply a temporary oversight in test procedures rather than a mechanical issue, but it warrants scrutiny of the 2022 test centre’s thoroughness. The gap between the 2023 and 2025 tests—nearly two years—is also notable, as it exceeds the standard 12-month interval, potentially masking early-stage failures in components like the exhaust system or electricals. A buyer should prioritise an in-person inspection of the suspension system, particularly the rear coil springs and bushes, as these are common failure points on this model and often go unnoticed until they bind or degrade. The brakes, while not explicitly flagged, should be checked for uneven wear or corrosion on the calipers and discs, especially if the bike has been stored for long periods. Corrosion on the frame, especially around the fuel tank mounting or rear subframe, is another critical area given the low mileage and potential for moisture ingress. Finally, the electrical system—including lights, switches, and the battery—should be tested, as these components degrade passively over time and are frequently overlooked in low-mileage vehicles. The 2022 failure without defects suggests a review of the test report for any unrecorded advisories or discrepancies.
