2004 Triumph Bonneville T 100 0.8L Petrol · DX04 FYM

The Triumph Bonneville T100 shows an unblemished MOT history, with the most recent test on 2 September 2025 at just 4,925 miles—well within the 12-month cycle. No advisories or defects were recorded across any of the five consecutive passes, indicating a vehicle that has consistently met DVSA standards for brakes, emissions, suspension, and structural integrity. The absence of recurring issues suggests that, at least on paper, the bike has been maintained at a basic level without any obvious neglect or mechanical degradation. That said, the 2025 test was conducted just over a year ago, meaning the vehicle is now due for its next MOT. While this is standard practice, the low mileage since then raises questions about whether the bike has been ridden regularly or stored. The recorded mileage of 4,925 miles over nearly 22 years—an average of around 224 miles annually—is extraordinarily low for a motorcycle of this age. Between the 2016 and 2019 tests, the bike accumulated only 125 miles in three years, and since the last MOT in 2025, it has barely moved. Such minimal usage could imply prolonged storage, which may accelerate wear on components like the battery, tyres, and rubber seals. The lack of mileage gaps or sudden spikes also suggests the vehicle has not been subjected to heavy or varied riding conditions, which might otherwise stress suspension bushes, chain tensioning systems, or throttle linkages. However, the consistency of the MOT passes implies that even with limited use, the owner has not overlooked critical maintenance. Given the low mileage and clean MOT record, a buyer should prioritise an inspection of high-friction components that degrade even with minimal use. The battery, last tested in 2025, should be checked for voltage and corrosion at terminals—prolonged inactivity can lead to sulfation. Tyres, though not flagged in MOTs, may have developed dry rot or uneven wear due to storage; tread depth and sidewalls should be examined closely. The chain and sprocket require inspection for stretch or rust, as static conditions can accelerate corrosion. Suspension components, while not historically problematic, should be tested for stiffness or binding, particularly if the bike has been stored on uneven surfaces. Finally, a thorough check of the electrical system—including lights, switches, and wiring harnesses—is essential, as moisture and oxidation can compromise functionality over long periods of inactivity. The absence of advisories does not guarantee these areas are flawless, especially given the bike’s extended periods of disuse.
