1999 Yamaha SR125 0.1L Petrol · T335 GJB

The vehicle’s most recent MOT test on 2025-05-21 at 17,232 miles confirmed full roadworthiness with no defects recorded, maintaining a consistent pass history across all four tests. There is no evidence of recurring mechanical failures or advisories, suggesting the vehicle has been operated under stable conditions without significant neglect. The absence of major faults in the past two years—including no indications of suspension degradation, binding brakes, or structural corrosion—implies that core systems have been either well-maintained or have not yet reached critical wear thresholds. However, the lack of advisories does not preclude hidden issues, particularly in components not routinely tested under MOT regulations. The recorded mileage of 17,232 miles over nearly 27 years equates to an average of approximately 638 miles annually, which is unusually low for a vehicle of this age. The intervals between tests reveal no rapid accumulation of miles—each test occurred roughly 12–14 months apart, with mileage increases of around 50–150 miles per year. This pattern suggests prolonged periods of inactivity rather than regular use. While low mileage can reduce wear on high-stress components like the engine or transmission, it also raises concerns about fluid degradation (e.g., oil, brake fluid, coolant) and potential stagnation-related issues such as seized fasteners or degraded seals. Given the sparse MOT history, a prospective buyer should prioritise a thorough inspection of components not routinely checked during MOTs. Focus on the suspension, particularly the condition of the rear swingarm pivots and fork seals, as these are prone to corrosion and wear over extended periods of inactivity. Examine the brakes for uneven pad wear or glazing, as low mileage can mask gradual degradation of friction materials. The drivetrain, including the chain (if applicable) and sprocket, should be inspected for rust or excessive slack, while the engine’s compression and valve clearance should be checked for signs of wear from prolonged storage. Structural integrity of the frame and fuel system integrity—especially for any stored fuel—are also critical, given the vehicle’s age and the potential for perished hoses or degraded rubber components.
