2020 Triumph Bonneville 0.9L Petrol · OV70 VOJ

The Triumph Bonneville has maintained a clean MOT record with no defects recorded across the most recent three tests, all of which passed without fail. The latest inspection on 23 July 2025, at just 311 miles, confirms the vehicle remains roadworthy under current DVSA standards. There is no evidence of recurring mechanical issues, and the absence of advisories suggests no critical components have been overlooked in prior servicing. However, the test’s proximity to the current date—just over a year old—means some wear patterns may have developed since then, particularly in areas prone to low-mileage degradation such as suspension lubrication or minor fluid leaks. The recorded mileage of 311 miles over six years, averaging approximately 52 miles annually, is exceptionally low for a vehicle of this age and type. This suggests prolonged periods of inactivity, which can accelerate certain forms of wear, such as dried-out suspension bushes, seized wheel bearings, or degraded rubber components like throttle bodies or brake hoses. The minimal mileage increments between tests—ranging from just 11 to 11 miles between 2023 and 2025—are unusual and may indicate the vehicle has spent extended time stationary, potentially exacerbating issues like corrosion or fluid stagnation. Buyers should verify whether the vehicle has been stored properly, as prolonged immobility can lead to hidden mechanical deterioration. Given the lack of defects in the MOT history, the primary focus for an in-person inspection should centre on components often affected by low-mileage stagnation. Check for signs of seized or stiff suspension joints, particularly the rear swingarm pivots and front fork seals, as these can degrade without regular movement. Inspect the wheel bearings for play or excessive heat when the wheels are spun, as prolonged inactivity can cause them to seize. Examine the brake system for corrosion on caliper slides or binding calipers, which might not have been detected in a static MOT test. Additionally, assess the exhaust system for rust or leaks, as moisture accumulation during storage can accelerate corrosion. The engine bay should be scrutinised for dried-out fluids, such as coolant or oil, which may have settled or degraded over time. Finally, verify the battery health, as low usage can lead to sulfation and reduced capacity.
