2015 Harley-Davidson XL 1.2L Petrol · BF15 AON

The 2015 Harley-Davidson XL currently sits in a failed MOT state as of the test conducted today, 16 June 2026, at 5,096 miles. The maintenance trend is clearly worsening. After four consecutive clean passes between 2020 and 2024, this latest test has flagged three distinct defects, all pointing toward neglect of basic cosmetic and lighting components rather than a sudden mechanical failure. The exhaust is registering as noisy under item 8.1.1(a), the registration plate lamp is missing entirely under 4.7.1(b)(ii), and critically, all rear direction indicators are absent, with only bar-end units fitted that are not clearly visible from the rear when the rider is seated, failing 4.4.1(a)(ii). These are not complex mechanical faults, but they do indicate the bike has either been poorly modified or inadequately maintained in its most recent period of use. The mileage profile tells a story of extremely light use. From 1509 miles in May 2020 to 4,754 miles in May 2024, the bike covered roughly 3,245 miles across four years. Then, in the twenty-three months between May 2024 and today, it added only 342 miles. That is a dramatic drop in annualised usage, from approximately 811 miles per year down to roughly 175 miles per year. Long periods of standing can cause stale fuel, perished rubber brake hoses, degraded tyre sidewalls from ozone cracking, and corrosion in the exhaust system, which may well explain the noisy exhaust noted in today's failure. The low mileage does not automatically mean low wear in this context; it can mean the opposite for perishable components. A buyer should approach this machine with suspicion regarding its storage conditions and recent activity. The failed exhaust noise check warrants a close visual inspection of the full exhaust system for internal corrosion, holed baffles, or loose mounting brackets that could have deteriorated during prolonged inactivity. The missing rear indicators and registration plate lamp suggest either a botched custom lighting install or simple neglect; either way, the wiring loom behind the seat and under the rear mudguard should be inspected for damaged connectors, chafed cables, or amateur splices. Given the extended periods of low use, the brake fluid should be tested for moisture content, the tyres checked for date codes older than five years regardless of tread depth, and the fuel system assessed for varnish or contamination. The mechanical core of the engine and drivetrain appears sound based on the clean pass history, but the peripheral systems and cosmetic compliance are clearly substandard today.
