2021 Yamasaki YM 50-10 0.1L Petrol · KM71 AAZ

The latest MOT test conducted in October 2024 resulted in a pass, following a failure ten days earlier regarding a non-functional offside rear direction indicator. This indicates that the vehicle's immediate electrical faults are being addressed. However, the maintenance trend shows a lack of preventative action regarding the drivetrain, as the advisories for a worn and loose drive chain and a worn rear sprocket were present in both the failed test and the subsequent pass. This suggests that while the vehicle is currently roadworthy, the drivetrain components are in a state of progressive wear that will soon require replacement. The recorded mileage of 6,929 miles over a five-year period represents very low annual usage, averaging approximately 1,386 miles per year. While this low mileage generally implies less mechanical fatigue on the engine and gearbox, it also suggests the vehicle may have spent extended periods stationary. Such usage patterns can lead to specific maintenance issues that are not directly related to distance, such as the degradation of fluids and the perishing of rubber components, which must be closely scrutinised during an inspection. When conducting a test ride, pay close attention to the drive system. The recurring advisories for the chain and sprocket mean you should listen for excessive chain slap, rattling, or a jerking sensation during acceleration, which are symptoms of a loose or worn chain. Visually inspect the rear sprocket teeth for a hooked or pointed profile, which indicates advanced wear. Additionally, test the feel of the nearside clutch and offside brake levers; since they were noted as being shortened, ensure they provide adequate lever travel and do not feel spongy or overly light. Given the low mileage, a thorough physical inspection is required to check for age-related degradation. Examine the tyre sidewalls for any signs of cracking or perishing, as rubber can harden and fail due to age even if the tread depth remains high. Check for surface corrosion on the brake discs and the drive chain, and ensure the calipers are not binding due to lack of use. Finally, verify the service history to confirm that oil and hydraulic fluids have been changed according to the manufacturer's time-based intervals rather than solely on mileage, to ensure the integrity of the lubrication and braking systems.
