2004 Harley-Davidson XL Sportster 1.2L Petrol · OU04 WHW

The vehicle most recently passed its MOT on 14 May 2026, and the overall maintenance trend is exceptionally stable. With a consistent history of passes over the last decade, the vehicle demonstrates a high level of sustained roadworthiness. The only recorded failure occurred in 2016 and was limited to registration plate dimensions, which is a minor administrative defect with no impact on mechanical integrity. The recent appearance of an advisory regarding a noisy rear exhaust indicates the onset of wear or deterioration in the exhaust system, but the general trajectory remains positive. With a recorded mileage of 28,397 miles over a 22-year lifespan, this motorcycle has averaged approximately 1,291 miles per year. This is considered very low usage for its age. While low mileage generally suggests reduced wear on the engine internals and drivetrain, it often implies that the vehicle has undergone periods of prolonged standing. Such usage patterns can lead to specific degradation issues caused by inactivity rather than mechanical wear, requiring a different approach to the pre-purchase inspection. Given the low annual mileage and age, a physical inspection must prioritise time-based degradation. Particular attention should be paid to the tyres; the buyer should check the sidewalls for perishing, cracking, or flat spots, as rubber hardens over time regardless of remaining tread depth. Inspect the brake discs for surface corrosion or pitting and ensure the calipers are not binding, which is a common occurrence for vehicles that spend long periods stationary. The health of the 12V battery should also be verified, as infrequent use often leads to premature cell failure. Regarding the recent advisory, the buyer should listen for excessive drone or audible leaks from the rear exhaust during the test drive, as this may indicate a failing baffle or corrosion in the pipework. It is also critical to verify the service history to ensure that fluids, specifically engine oil and brake fluid, have been changed according to a calendar schedule rather than mileage intervals, as these fluids degrade chemically over time. Finally, a thorough check of the chassis and engine casings for any signs of standing corrosion or oxidation is recommended to ensure the structural integrity has been preserved.
