2006 Harley-Davidson Flstf 1.6L Petrol · KX55 SUY

The vehicle’s most recent MOT tests, conducted on July 7, 2025 , reveal an unusual but technically compliant history—it passed once and failed once on the same day at 6,837 miles , with no recorded defects or advisories in either instance. This suggests the tester did not identify any major failings, though the duplicate entry implies either a procedural anomaly or a minor oversight in documentation. The preceding tests, all passing without failings, indicate a stable maintenance record over the past four years, with no evidence of recurring mechanical issues. However, the lack of advisories or defects in any test raises questions about whether critical components—such as suspension bushes, coil springs, or binding calipers—were ever scrutinised beyond basic compliance. The recorded mileage of 6,837 miles at the latest test, combined with the vehicle’s 2006 production date, points to an exceptionally low annual average of 342 miles , far below typical usage patterns for this class of motorcycle. This suggests prolonged periods of inactivity, which could accelerate wear on seals, fluids, and rubber components due to stagnation. The mileage increment between tests remains consistent—around 250 miles per year —with no sudden spikes or gaps that would indicate aggressive riding or neglect. While low mileage generally reduces mechanical stress, it also increases the risk of fluid degradation (e.g., brake fluid, coolant) and corrosion from moisture accumulation in standing conditions. Given the absence of failings or advisories, an in-person inspection should prioritise fluid condition and integrity , particularly brake fluid (for moisture contamination) and engine oil (for sludge or degradation). The suspension system—especially rear shock absorbers and steering head bearings—should be checked for excessive play or corrosion, as prolonged inactivity can exacerbate wear in these areas. Tyres, despite no recorded issues, warrant inspection for uneven wear or embedded debris, which could indicate past neglect. Finally, the exhaust system and catalytic converter should be examined for leaks or excessive corrosion, as these components are prone to deterioration even with minimal use. The lack of advisories does not preclude hidden wear, so a thorough mechanical review is essential.
