2020 Triumph Bonneville 0.9L Petrol · YN70 BZT

The Triumph Bonneville’s most recent MOT test on 26 June 2025 confirms it remains roadworthy, with no defects recorded at 2,701 miles. The absence of advisories or failings across three tests—including a double entry in July 2024 at just 215 miles—suggests a stable maintenance history, though the rapid rescheduling of tests within days is unusual and warrants scrutiny. The lack of recurring issues implies the vehicle has not experienced mechanical failures tied to wear, but the extremely low mileage raises questions about its storage conditions and potential neglect of fluid changes or minor servicing. The recorded mileage of 2,701 miles over six years—approximately 450 miles annually—is exceptionally low for a motorcycle of this age. The sudden accumulation of 215 miles between the 2024 tests, followed by no further mileage until the 2025 pass, indicates either a brief period of active use or an error in logging. Such erratic patterns often correlate with vehicles stored for extended periods, where fluids degrade, rubber components dry out, and corrosion may develop unnoticed. The absence of mileage between tests also means critical intervals for oil changes, chain tensioning, or brake fluid refresh may have been overlooked. Given the sparse MOT history, a buyer should prioritise an inspection of the chain and sprocket for excessive wear or rust, as low-mileage bikes often suffer from static corrosion. The suspension bushes and coil springs should be checked for perished rubber or binding, particularly if the bike has been stored without movement. Brake discs and pads, while not flagged in tests, may have deteriorated due to lack of use, so binding or uneven wear should be tested under load. Finally, examine the frame and fuel tank for surface corrosion, as prolonged standing can accelerate rust formation even in low-humidity environments. The lack of advisories does not preclude these areas from requiring attention.
