2005 Yamaha YFM 660 0.6L Petrol · AE54 XOO

The maintenance trend for this 2005 Yamaha YFM 660 appears stable, though the MOT record is severely outdated relative to the current date of July 2026. The most recent test occurred on 7 October 2021 at 8,310 miles, resulting in a clean pass with no defects recorded. A preceding test on 6 October 2021 at the identical mileage shows a failure, yet notably lists no defects. This anomaly strongly suggests a procedural or administrative failure, such as a documentation discrepancy or an aborted inspection, rather than a sudden mechanical fault, given the immediate defect-free pass the following day. Without a valid MOT for nearly five years, the current roadworthiness status remains entirely unverified. The recorded mileage of 8,310 miles is exceptionally low for a 21-year-old machine, equating to an average of just 396 miles per year. The data shows zero mileage accumulation between the 2021 tests and the present day, indicating the vehicle has either been stored unused or has not been presented for statutory testing since October 2021. Prolonged stationary storage poses distinct mechanical risks, including stale fuel, perished rubber components, and corroded brake systems, which standard MOT records do not capture. The sparse data prevents any assessment of wear trends, leaving the true condition of consumables and structural components unknown. A buyer must conduct a rigorous physical inspection to verify the condition of components that deteriorate through age and inactivity rather than mileage. Focus on the structural integrity of the chassis and suspension mounts, checking for corrosion that can compromise the frame during off-road use. Inspect all rubber bushes, tyre sidewalls, and seals for perishing, as these degrade naturally over time regardless of use. The braking system requires close scrutiny; binding calipers and pitted brake discs are common on machines left standing, directly impacting stopping efficiency. Drain and inspect the fuel system for varnish or contamination, and assess the drivetrain for stiffness or seization. The absence of recent mechanical verification means these elements must be thoroughly evaluated before any operation.
