2012 Triumph Bonneville 0.9L Petrol · HY12 WNH

The vehicle currently holds a roadworthy status following a pass in June 2026 at 9,228 miles. However, the immediate mechanical history shows a worsening trend regarding the front suspension. A failure occurred in May 2026 at 9,209 miles due to a serious fluid leak on the nearside front shock absorber, which followed an advisory for light oil misting in the June 2024 test at 7,671 miles. While the bike passed the subsequent test, the progression from misting to a major leak indicates component failure. The mileage pattern is exceptionally low for a 14-year-old motorcycle, totaling only 9,228 miles and averaging roughly 660 miles per year. This low usage suggests the bike sits stationary for long periods, which can lead to degradation of rubber components and fluid breakdown. There are significant gaps between tests, such as the 22-month interval between August 2022 and June 2024, and the 24-month gap between June 2024 and June 2026. These intervals of infrequent use often correlate with the aging of seals and tyres despite the low mechanical wear. A buyer must prioritize inspecting the front suspension assembly to ensure the shock absorber has been properly replaced and not merely patched. The inspection should also target the braking system, as the record shows recurring fluctuations in brake effort dating back to 2016 and 2017, which indicate corroded rotors or sticking calipers caused by inactivity. Given the low mileage and age, check for dry rot on tyre sidewalls, perished brake lines, and any surface corrosion on the frame or exhaust, as these are common issues for vehicles that are infrequently driven.
