2020 Harley-Davidson Fxbb Street BOB 1745 20 1.7L Petrol · CK20 VML

The vehicle is currently roadworthy, though the most recent inspection indicates a shift from previous clean records. During the test on 11 March 2026 at 40,100 miles, the tester flagged an advisory for a noisy exhaust that may not be standard. This suggests an aftermarket exhaust system or a developing leak in the manifold assembly. Despite this finding, the overall maintenance trend remains stable over the last four years, following several clean passes between 2022 and 2025. The mileage progression is consistent with typical annual use for this age, averaging approximately 6,700 miles per year. There is a significant gap in usage between the March 2022 test at 15,686 miles and the March 2023 test at 27,258 miles, where the bike covered over 11,000 miles in twelve months. Since then, the accumulation has steadied to roughly 3,000 to 3,300 miles per test interval. This regularity suggests the vehicle has been used consistently rather than suffering from long periods of stagnation. A buyer should conduct a close inspection of the exhaust system to determine if the noise stems from a high-performance modification or a failing structural component. The 2023 advisory regarding a rear tyre worn close to the legal limit indicates that the previous owner occasionally neglected basic consumable replacement until the threshold was met. Since no structural corrosion or brake-related defects were recorded in the history, the focus should remain on the current state of the tyres, chain tension, and fluid seals to ensure the 40,100-mile mark has not resulted in premature wear of the drivetrain components.
