2015 Triumph Bonneville 0.9L Petrol · EY65 OAL

This Triumph Bonneville has demonstrated a stable roadworthiness trend over the past two years, with no defects or advisories recorded in any of its MOT tests. The most recent test on 2025-04-30—just under a year ago—confirmed the vehicle passed without issue, despite the unusual duplicate entry (one pass, one fail at identical mileage). This suggests the tester may have misapplied the result, but the absence of recurring faults indicates the core systems were functioning as expected at that time. However, the lack of advisories or warnings in any of the five tests is notable; while this implies no hidden issues were detected, it also raises questions about whether minor wear or pre-existing conditions were overlooked due to the vehicle’s low mileage. The recorded mileage of 9,718 miles over nearly 11 years—roughly 883 miles annually—is unusually low for a vehicle of this age, particularly given its classic motorcycle status. The gap between tests is consistent, with mileage increments of around 400 miles per year, which suggests the bike has spent extended periods stationary rather than in regular use. This could mean the previous owner prioritised preservation over frequent riding, or the vehicle may have been stored unsuitably, increasing the risk of corrosion or component degradation from moisture and lack of movement. The most recent mileage reading aligns with the 2025 test date, indicating no significant usage since then. Given the lack of MOT advisories or defects, a buyer should prioritise an in-person inspection of components that are not routinely tested but are critical for a classic bike of this age. Focus on the frame for signs of stress cracks or weld fatigue, particularly around the fuel tank mounting points and rear subframe—common weak areas in Triumphs of this era. The suspension bushes and coil springs should be examined for perished rubber or excessive play, as these are often neglected in low-mileage bikes but can fail catastrophically. The brakes, while not flagged, warrant scrutiny: check for uneven wear on the discs and pads, as well as the condition of the hydraulic lines for leaks or corrosion. Finally, inspect the exhaust system for rust penetration at the heat-shield junctions and the integrity of the catalytic converter, as these are frequently overlooked but can lead to emissions failures or structural compromise. The absence of MOT warnings does not guarantee these areas are sound.
