2010 Harley-Davidson XL 1200 X Forty Eight 1.2L Petrol · HD60 ADE

A persistent, multi-year advisory regarding a noisy exhaust system defines the mechanical profile of this motorcycle, appearing in every recorded test from 2021 through to the most recent pass on 13 August 2026. While the vehicle has successfully passed its inspections throughout this period, the continuity of this specific defect suggests a long-standing issue with the exhaust assembly, such as a loose mounting, a developing leak at a flange, or internal degradation of the silencer. This pattern indicates a stable but unresolved condition that has remained constant for at least five consecutive testing cycles. The recorded mileage of 13,651 miles against a 2010 manufacture date represents an unusually low annual accumulation of approximately 853 miles per year. For a vehicle of this age, such low usage often implies infrequent operation, which can lead to different mechanical considerations than high-mileage vehicles. While there is less wear on the drivetrain and engine internals, long periods of inactivity can affect rubber components, seals, and fluid integrity. The MOT history shows consistent annual testing without significant gaps, which provides a continuous record of its roadworthiness despite the low frequency of use. A prospective buyer should focus specifically on the exhaust system to determine the severity of the recurring advisory. During a test ride, listen closely for irregular popping, rhythmic tapping, or increased decibel levels that fluctuate with engine RPM, as these can indicate exhaust leaks or structural issues within the manifold or silencer. It is also advisable to inspect the exhaust mounting points and brackets for signs of loosening or vibration-induced wear, as the advisory has remained unchanged for several years. Beyond the exhaust, the low mileage profile warrants a physical inspection of all perishable components that may degrade through age rather than wear. Check for any signs of weeping from gaskets or seals, particularly around the engine and primary drive, and ensure that any rubber hoses or cables do not show signs of cracking or perishing. While the MOT record is relatively clean of other defects, the combination of low usage and a chronic exhaust advisory means the mechanical focus should remain on the integrity of the exhaust assembly and the condition of components that may have sat idle for extended periods.
