2015 Harley-Davidson Fxsb 1.7L Petrol · PO15 WSN

The 2015 Harley-Davidson FXSB presents a stable and improving maintenance trend, culminating in a fully clean MOT pass on 28 May 2026 at 17,136 miles with zero defects recorded. That result is the fifth consecutive pass in the vehicle's history, and the trajectory is clearly positive. The only advisory on file, an exhaust noise defect noted on 28 April 2022 at 12,792 miles, has not reappeared in any subsequent test, suggesting the owner rectified the issue and has maintained the motorcycle to a consistent standard since. No recurring faults, no new advisories, and no failures indicate a well-kept machine with no emerging mechanical concerns. The mileage pattern tells a clear story of very light use. Across roughly eleven years of ownership, the odometer has advanced just 17,136 miles, averaging approximately 1,558 miles per year. Annual intervals between tests show incremental gains of around 800 to 1,300 miles, with the largest single jump occurring between April 2023 at 13,624 miles and April 2024 at 15,073 miles, an increase of 1,449 miles. There are no suspicious gaps or sudden spikes that would suggest odometer tampering or prolonged periods of neglect. The accumulation is steady and consistent with a motorcycle ridden sparingly but regularly enough to keep seals, fluids, and moving components exercised. Despite the clean paper record, a buyer should still conduct a thorough in-person inspection focused on areas the MOT does not fully interrogate. The 2022 exhaust noise advisory warrants a close visual and auditory check of the full exhaust system, particularly the header flanges, clamps, and muffler seams, to confirm no new leaks or deterioration have developed since. Given the low annual mileage, fuel system components such as fuel lines, the fuel pump injector o-rings, and tank interior should be inspected for stale fuel corrosion or perished rubber. Tyre date codes deserve attention; even with ample tread depth, rubber older than five years can harden and compromise grip, and a motorcycle sitting for long intervals between rides is especially prone to flat-spotting and sidewall cracking. Suspension and steering head bearings should be checked for notchiness or play, as infrequent use can cause brinelling in bearings that see only light loads. Brake calipers and master cylinder seals merit inspection for sticking or fluid contamination, since a motorcycle that stands for extended periods can develop binding pistons and degraded brake fluid from moisture absorption. Chain tension, sprocket tooth profile, and final drive lubrication should be assessed, as a poorly maintained chain on a low-mileage bike can still corrode from neglect. The clean MOT history is encouraging, but low mileage alone does not guarantee mechanical soundness, and hands-on verification remains essential.
