2017 Harley-Davidson Flfb Fatboy 1745 18 1.7L Petrol · HD17 FAB

A completely unblemished MOT record across five consecutive tests demonstrates a strong and consistent roadworthiness profile for this 2017 Harley-Davidson Fat Boy. Every annual examination from 2021 through the most recent pass on 5 September 2025 returned a clean result with no advisories, defects, or failures recorded. Such an unbroken clean sheet across multiple testing cycles is uncommon and points to either genuinely low wear rates or diligent pre-test rectification. For a prospective buyer, this consistency provides immediate confidence that the machine has met basic safety and structural standards year after year without the need for component replacements flagged at test time. With 17,552 miles accumulated over nine years, this Fat Boy has covered roughly 1,950 miles annually, placing it firmly in low-mileage territory for a motorcycle of this age. The usage pattern shows steady annual accumulation without significant gaps between tests, suggesting the vehicle has remained in regular but light use rather than being laid up for extended periods. Mechanically, low annual mileage on a big-capacity V-twin like the 1745cc Milwaukee-Eight engine means the powertrain itself is unlikely to have suffered from excessive internal wear, but the relatively modest running does raise questions typical of any low-mileage machine: seals, gaskets, and rubber components can deteriorate faster from infrequent use than from regular riding, and corrosion can take hold on unprotected surfaces during periods of standing. The consistent year-on-year testing does, however, indicate the bike has not been off the road for any prolonged stretch. With no specific components flagged across the MOT history, buyer guidance must focus on the areas that low-mileage Harley-Davidsons commonly develop issues with beyond the scope of standard testing. On a test ride, pay particular attention to the primary and final drive system, listening for any clunks, rattles, or vibration irregularity from the transmission that might suggest worn components. Feel for smooth throttle response and check for any tendency to stall or run unevenly when cold, which can indicate fuel system or sensor issues that accumulate on infrequently ridden bikes. Inspect the exposed V-twin engine cases, pushrod tubes, and primary cover for any signs of oil seepage, as even minor misting from these areas is worth noting. Brake feel should be firm and progressive, with no binding or sponginess at either the front disc or rear system, and the brake lines, particularly where they route near the exhaust, should be checked for any heat-related deterioration. For the chassis and running gear, inspect the front fork stanchions for oil residue or corrosion pitting, and test the suspension through normal riding to ensure no knocking or harshness over uneven surfaces. The Fat Boy's fat front end places additional stress on head bearings and steering damper components, so check for any notchiness or hesitation when turning the handlebars from lock to lock at low speed. Examine the wheels, particularly the solid-disc front wheel and the chunky rear, for any impact damage or run-out. Given the low mileage and clean MOT history, requesting evidence of recent servicing including oil changes, primary fluid, and brake fluid replacement is advisable, as these consumables degrade with calendar age regardless of mileage. A compression test and a check of the battery's resting voltage would also be prudent given the bike's relatively low annual use, ensuring the machine is mechanically sound beneath its faultless paper trail.
