2019 Triumph Bonneville 1.2L Petrol · EX19 CKA

The most recent DVSA examination on 7 March 2026 recorded a PASS outcome, with two advisories raised concerning the front wheel rim bead and rear brake disc wear. Across the recorded MOT history, the Bonneville has demonstrated a stable maintenance profile, with all tests from 2022 onwards resulting in a pass and no defect progressing into a failure category. The only recorded failure was on 12 February 2022 for an inoperative headlamp dipped beam, which was remedied and passed at the subsequent retest seven days later, suggesting an isolated component rather than a systemic electrical fault. The reappearance of the front wheel rim bead distortion advisory across both 2025 and 2026, alongside a consistent rear brake disc advisory, indicates that while the vehicle remains roadworthy, certain wear items have settled into a recurrent pattern that warrants careful buyer attention. With 25,879 miles recorded over a seven-year ownership span, annual mileage averages approximately 3,697 miles, which is markedly low for a modern motorcycle and strongly indicative of irregular use or extended periods of standing. Such a usage profile typically means that high-stress mechanical components such as the engine internals, transmission, and chain drive have experienced limited wear, but ancillary systems more affected by calendar age than by mileage are likely to require closer scrutiny. The mileage consistency across MOT entries suggests no dramatic accumulation or gap periods, pointing to a vehicle that has been used sparingly but steadily, consistent with a leisure or weekend motorcycle rather than a daily commuter. Given the recurring advisory regarding the front wheel having a slightly distorted bead rim, the prospective buyer should physically inspect the front wheel for any visible deformation of the rim flange, paying particular attention during a test ride for handlebar oscillation, uneven steering feedback, or low-speed instability that could indicate a worsening impact or corrosion beneath the tyre bead. The rear brake disc advisory noted as worn but not excessively should prompt a visual examination of the disc surface for scoring, lipping, and minimum thickness, and the caliper should be checked for any signs of binding or uneven pad wear, particularly given that prolonged standing periods can lead to corrosion-induced piston seizure. On a test drive, listen for any brake shudder or pulsation under firm application and verify that the rear brake delivers consistent feel without dragging. Beyond the recorded advisories, the age and low-mileage profile of this Bonneville demands several time-based inspection points regardless of the clean MOT record. Tyres should be examined closely for sidewall perishing or cracking from age, even where tread depth appears adequate, and the date code on each tyre should be reviewed, as rubber compounds degrade after roughly five years irrespective of wear. The 12V battery is particularly susceptible to sulphation and reduced capacity from irregular charging cycles, so its voltage under load and the date stamp should be verified. Coolant and brake fluid both suffer calendar-based degradation and should ideally have been replaced on schedule regardless of mileage, while chain and sprocket condition, fork seal integrity for any weeping, and the state of the fuel system including injector or carburettor cleanliness should all be assessed. A thorough cold start observation, listening for any irregular idling, smoke emissions, or warning lights, together with verification of full service book stamping at the manufacturer-recommended intervals, will provide the clearest indication of how this low-mileage example has been preserved between uses.
