2021 Triumph Bonneville Speedmaster 1.2L Petrol · JC71 JRC

The Triumph Bonneville Speedmaster has maintained a clean MOT history with no defects recorded in either of the two most recent tests, most recently passing on 8 October 2025 at just 11,070 miles. This suggests a stable roadworthiness trend over the past year, with no recurring issues or advisories to indicate deteriorating mechanical conditions. The absence of any failings—even minor—implies that the vehicle has been kept in a state of basic compliance, though this does not preclude hidden wear or deferred maintenance beyond MOT scope. The recorded mileage of 11,070 miles over approximately five years equates to an unusually low annual average of around 2,214 miles. This pattern, combined with the two-year gap between MOT tests, raises questions about the vehicle’s storage conditions or usage. Such low mileage could indicate prolonged periods of inactivity, potentially accelerating issues like suspension fluid degradation, battery sulphation, or minor corrosion from moisture exposure. The lack of intermediate MOTs or service records further obscures whether routine upkeep—such as brake fluid changes, fuel system maintenance, or tyre rotations—has been consistently performed. Given the sparse MOT history, a buyer should prioritise an in-person inspection of critical components that are not routinely tested. Focus on the suspension, particularly coil springs and bushes, for signs of fatigue or dry rot, as low mileage does not exempt these from wear over time. The brakes, while not failed, should be checked for uneven pad wear or binding calipers, especially if the vehicle has been stationary for extended periods. Examine the exhaust system for leaks or corrosion, particularly around joints, and inspect the battery terminals for oxidation, which can develop even with minimal use. Structural integrity, including the frame rails and subframe mounts, should also be scrutinised for hidden rust or misalignment, as these issues often go unnoticed until they compromise safety.
