2012 Yamaha YBR 125 0.1L Petrol · AF12 UBR

Mechanical concerns regarding the steering assembly and exhaust system represent the most immediate points of interest following the most recent pass on 05 September 2025. While the vehicle has maintained a consistent pass record since 2020, the transition from clean tests in recent years to multiple advisories in the latest inspection indicates a shift in the mechanical profile. Specifically, the presence of a stiff or notchy steering headbearing and a noisy exhaust suggests that components which were previously within tolerance are now showing signs of wear or degradation. The recorded mileage of 4,393 miles over a 14-year period reflects an exceptionally low annual usage rate of approximately 314 miles. This pattern of minimal road use can result in specific mechanical implications, such as the degradation of rubber components or the potential for parts to seize due to infrequent operation. While low mileage generally implies less wear on the drivetrain and engine internals, the MOT history shows that even with low usage, specific items like the drive chain and steering components require attention, as evidenced by the 2020 failure regarding an excessively tight chain and the current advisory regarding the steering headbearing. A prospective buyer should pay close attention to the steering feel during a test ride to evaluate the reported stiffness in the headbearing. Any sensation of resistance when turning the handlebars, a notched or uneven feeling through the grips, or a physical hesitation during low-speed manoeuvres would confirm the advisory. Furthermore, the noisy exhaust should be assessed by listening for any unusual vibrations, rattling, or changes in pitch during acceleration and idling, which may indicate loose mounting hardware or internal exhaust degradation. The advisory regarding the rear tyre being worn close to the legal limit necessitates an immediate inspection of the remaining tread depth and the overall condition of the rubber. Beyond tread depth, check for any signs of sidewall cracking or perishing, which can occur on vehicles with low annual mileage and long periods of stationary use. Additionally, the previous failure regarding wheel alignment should be monitored by checking for any unintended pulling or instability when riding in a straight line, ensuring that the steering geometry remains stable despite the reported headbearing issues.
