2018 Triumph Bonneville 1.2L Petrol · PP66 BMP

The Triumph Bonneville in question has maintained a consistent MOT history, with every test since June 2022 passing without any recorded defects or advisories. The most recent inspection on 1 August 2025—just over a year ago—confirmed the vehicle’s compliance with all current roadworthiness standards, including emissions, brakes, steering, and suspension. There is no evidence of recurring mechanical issues, and the absence of advisories suggests previous owners adhered to basic servicing requirements. However, the lack of defects does not preclude wear that may not yet be visible or detectable without a thorough mechanical inspection. The recorded mileage of 9,172 miles over eight years—approximately 1,146 miles annually—indicates unusually light usage for a vehicle of this age. The gap between tests, particularly the 14-month interval between the June 2023 and June 2022 MOTs, suggests prolonged periods of non-use, which could accelerate certain forms of degradation such as battery corrosion, tyre degradation, or suspension component drying out. The consistency in mileage increments (e.g., 1,779 miles between August 2023 and August 2024) further implies the vehicle was not actively driven during off-seasons, a pattern that may have implications for fluid levels, chain tension, and general mechanical readiness. Given the clean MOT record, a prospective buyer should prioritise an inspection of high-wear components that are not routinely checked during an MOT. The suspension—particularly the rear swingarm bushes, coil springs, and rear axle bearings—should be examined for excessive play or corrosion, as prolonged static periods can compromise rubber and metal fatigue. Brake discs and pads, while not flagged in past tests, warrant scrutiny for uneven wear or binding calipers, especially if the vehicle has been stored with wet brakes. The electrical system, including the battery and starter motor, should be tested, as low mileage increases the risk of sulphation or terminal corrosion. Finally, a thorough check of the exhaust system for leaks or structural weakness is advisable, as rust propagation can occur even in low-mileage vehicles exposed to varying weather conditions.
