2019 Herald SK 125-25B Scrambler 0.1L Petrol · AF68 AAV

The latest MOT test completed on 28 February 2025 resulted in a pass, but the report contains several advisories that indicate a downward trend in the vehicle's mechanical condition compared to previous years. While the 2024 inspection was entirely clean, the 2025 report highlights multiple areas of wear across the braking, drivetrain, and wheel assembly. This shift from a defect-free status to multiple advisories suggests that the vehicle is entering a phase where several consumable components are reaching the end of their serviceable life simultaneously, necessitating more frequent and potentially more costly maintenance. The recorded mileage of 34,379 miles over a seven-year period equates to an average of roughly 4,911 miles per year. This is relatively low usage for a motorcycle of this age, which may imply lighter overall mechanical stress on the engine. However, low annual mileage can often lead to other issues, such as component degradation due to standing time or infrequent use. The current state of the consumables, specifically the brake discs and drive chain, appears consistent with this mileage profile, where age-related wear is becoming more prominent than high-mileage attrition. During a test drive, particular attention must be paid to the braking system and the rear wheel assembly. The advisory regarding a binding front brake and a worn rear brake disc means you should check for any dragging sensation, excessive heat coming from the calipers after a short ride, or any pulsing through the brake lever or pedal. Furthermore, the reported slight play in the rear wheel bearing is a critical item to monitor. Listen for any rhythmic humming, growling, or grinding noises from the rear of the bike, and if possible, check for any lateral movement in the rear wheel while the bike is on a stand, as a bearing with play will eventually require replacement to ensure safety. The advisory for a worn rear drive chain sprocket also necessitates a thorough inspection of the drivetrain. Check the chain for excessive slack, stiffness, or kinking, and inspect the sprocket teeth for a hooked or sharpened profile, which indicates they are nearing the end of their life. Replacing the chain and sprockets as a matched set is highly recommended to prevent premature wear. Additionally, because the vehicle has seen relatively low annual mileage, inspect the tyres for signs of perishing or sidewall cracking, which can occur due to age even if the tread depth appears adequate. Finally, confirm that the service history includes regular oil and fluid changes based on time intervals rather than just mileage.
