2009 Harley-Davidson Flhr 1.4L Petrol · FP09 DBX

Structural integrity issues regarding the swinging arm define the recent history of this motorcycle, specifically a major failure in March 2026 due to corrosion on the nearside front of the arm. While the vehicle subsequently passed its test on 4 April 2026, this failure breaks a long sequence of clean passes dating back to 2020. The emergence of significant corrosion on a primary structural component suggests a shift in the vehicle's condition that warrants close scrutiny. An average annual accumulation of approximately 2,248 miles indicates relatively light usage for a motorcycle of this age. This low-mileage profile typically means less mechanical wear on the drivetrain and engine internals compared to high-mileage examples. However, the recent failure for structural corrosion despite low usage suggests that environmental factors or storage conditions may have had a more significant impact on the chassis than operational wear. A physical inspection should focus heavily on the repair carried out to the swinging arm to ensure the corrosion was fully remediated rather than superficially treated. Examine the nearside front of the arm for any remaining pitting, bubbling paint, or uneven surface textures that could indicate ongoing oxidation. Check all other structural joints and the frame for similar signs of corrosion, as the failure of one major component often points to vulnerability in other exposed metal areas. During a test ride, pay close attention to the stability of the chassis and the feel of the rear suspension. Listen for any unusual knocks or creaks when traversing uneven surfaces, which could indicate compromised rigidity or bushing wear associated with the previously corroded area. Ensure the motorcycle tracks straight and does not exhibit any unexpected lateral movement or instability under braking and acceleration, as these can be symptoms of structural deficiency in the swinging arm assembly.
