2007 Harley-Davidson Fxdb Street BOB 1.6L Petrol · AF07 EYX

The most recent DVSA MOT test dated 16 July 2026 resulted in a pass, with a single advisory recorded for an exhaust noise issue. Reviewing the broader history, the vehicle has passed every annual test without a single failure since at least 2019, indicating a stable and consistent maintenance pattern rather than any deterioration. The same single advisory concerning an excessively noisy exhaust has appeared on every test in the available record, which suggests a long-standing condition that has not progressed to outright failure. This consistency is encouraging from a structural and mechanical standpoint, as it shows no emerging advisories relating to suspension, braking, steering, lighting, or corrosion, all of which would typically appear on a motorcycle of this vintage if significant wear or degradation were present. The recorded mileage of 14,717 miles against a vehicle of approximately 19 years equates to an annual average of around 775 miles, which is exceptionally low even for a motorcycle. Such minimal usage raises the likelihood of extended periods of standing, during which components can deteriorate through inactivity rather than wear. The recorded mileages on the MOT certificates show only modest increments year on year, confirming that the bike has been used sparingly. While low mileage is generally favourable for major drivetrain components, it does introduce specific concerns relating to fluid degradation, internal corrosion of the braking system, and the condition of rubber and composite parts that can perish with age regardless of mileage covered. A prospective buyer should pay particular attention to the recurring exhaust noise advisory, as this has now been present for at least seven consecutive test cycles. A noisy exhaust on a Harley-Davidson Twin Cam can indicate failing gasket seals at the head pipe joints, a deteriorating baffle within the silencer, or corrosion of the outer skin allowing sound to escape. During a test ride, listen for changes in exhaust note under acceleration and deceleration, and inspect the header pipes and silencer joints for any visible soot staining, hairline cracks, or signs of active blowing. Given the bike's age, also examine the exhaust mounting brackets and the condition of the heat shields, as vibration over many years can loosen fixings even with low mileage. The original 2019 advisory also noted a nearside front tyre worn to 1.6mm, close to the legal minimum, which is unsurprising given the age of the rubber and reinforces the need to scrutinise tyre condition thoroughly regardless of tread depth, as old tyres can crack and perish on the sidewalls and shoulders. Beyond the recorded advisories, the low annual usage profile warrants a methodical inspection of components affected by standing rather than wear. Brake discs on a motorcycle that has covered few miles are prone to surface corrosion, which can manifest as brake shudder or uneven feel on the first application, and caliper pistons can seize from lack of use, so check for binding when the lever or pedal is released. The 12-volt battery, particularly if original or several years old, is highly likely to require replacement, and the charging system should be verified with a voltage check. Tyres, even if retaining legal tread, should be examined for sidewall cracking, dry rot, and check the production date code, as rubber compounds degrade with calendar age. Engine oil, primary chaincase fluid, and transmission fluid should all be considered due for replacement based on time elapsed rather than mileage, and the condition of fuel lines, seals, and the tank interior should be assessed, as ethanol-blended fuels can cause deterioration in infrequently used vehicles. Finally, the fork oil and suspension linkage bushes will benefit from inspection, as these can degrade and contaminate internally over prolonged periods of low use.
