2020 Harley-Davidson Fxfb FAT BOB 1745 20 1.7L Petrol · OY69 KZX

This motorcycle presents a clean bill of health. The most recent MOT, conducted on 9 May 2026 at 5,725 miles, passed with zero defects recorded. Looking back across the full history, the maintenance trend is entirely stable and unbroken. Every single test since February 2023 has returned a pass with no advisories or failures. For a Harley-Davidson Fat Bob, this is a strong indicator that the bike has been kept in sound mechanical order, with no recurring faults or emerging deterioration patterns flagged by any tester over the past three years. The mileage profile tells a very specific story about how this machine has been used. At just 5,725 miles, the annual average sits at roughly 954 miles per year, which is exceptionally low for a 2020 model. The increments between tests reveal long periods of dormancy. Between the February 2023 test at 5,429 miles and the May 2024 test at 5,638 miles, the bike covered only 209 miles in over a year. From May 2024 to May 2025, it added just 63 miles. The most recent twelve months saw a marginal increase of 24 miles. This is not a motorcycle that has been ridden hard or regularly. Such low usage raises different concerns than high mileage wear, particularly around fuel system condition, tyre age, and seal integrity from prolonged standing. Despite the clean MOT record, a buyer should still conduct a thorough physical inspection. Low-mileage motorcycles often suffer from perished rubber components, dried-out fork seals, and corroded brake lines caused by sitting idle rather than wearing out through use. Check the tyre date codes carefully; rubber degrades with age regardless of tread depth. Inspect the exhaust headers and downpipes for surface corrosion, which can develop from short trips that never allow the system to fully heat and dry. Examine the battery terminals and wiring harness for green corrosion, a common issue on bikes that sit between rides. The suspension and steering head bearings deserve close attention. Even with minimal mileage, a motorcycle that has been stationary for extended periods can develop flat-spotted bearings or stiff, dried linkage bushings. Compress the front forks and swingarm to check for smooth, unrestricted movement. While the MOT tester found no structural corrosion or mechanical defects, a buyer should still scrutinise the frame welds, particularly around the steering head and rear subframe, for any signs of rust jacking or paint bubbling. The clean MOT history is reassuring, but it does not replace a hands-on assessment of a machine that has spent more time on a stand than on the road.
