2021 Triumph Bonneville 1.2L Petrol · RE52 ELL

The most recent DVSA MOT test for this 2021 Triumph Bonneville was conducted on 7 May 2026, resulting in a PASS outcome with no defects or advisories recorded against the vehicle. The preceding test on 20 May 2025 also resulted in a clean PASS, with no advisory notes logged at that time either. With two consecutive advisory-free passes in the official record, the documented test history reflects a stable and well-maintained roadworthiness profile, with no recorded deterioration in any tested component category across the most recent statutory examinations. In the absence of any documented advisories relating to brake condition, tyre wear, suspension integrity, exhaust emissions, lighting, or structural corrosion, there is no direct evidence from the MOT file of any component approaching statutory failure thresholds. With a recorded mileage of 2,735 miles against a vehicle age of approximately five years, this Bonneville is demonstrating an exceptionally low annual utilisation rate of roughly 547 miles per year. Such low usage is typical of a leisure or weekend machine rather than a daily commuter, and it carries specific mechanical implications that diverge from those associated with higher-mileage examples. Components that rely on regular thermal cycling, lubrication distribution, and mechanical exercise can degrade through prolonged standing periods, even where total mileage is minimal. Rubber components can harden, brake discs and calipers can seize from lack of use, the 12V battery can lose capacity through repeated shallow discharge cycles, and engine and gearbox oil can degrade on a calendar basis rather than purely through service interval mileage. Given the clean MOT record and the low-mileage, leisure-use profile, a prospective buyer should undertake several physical inspections that the MOT history alone cannot capture. Tyres should be examined closely for sidewall perishing or cracking from age-related rubber degradation, even where tread depth remains adequate, and the manufacturing date code on each tyre sidewall should be checked, as tyres older than five years begin to lose structural integrity regardless of remaining tread. The brake discs should be inspected for surface corrosion, pitting, or any evidence of binding calipers, which can manifest on a test drive as pulling to one side, a spongy lever feel, or uneven pad deposition on the disc surface. The 12V battery should be load-tested, as low-mileage motorcycles are particularly susceptible to premature battery failure from chronic undercharging. All fluid systems, including engine oil, brake fluid, coolant where fitted, and final drive oil, should be evaluated against calendar-based service intervals rather than purely odometer-based schedules, and the service book should be verified for evidence of annual inspections or fluid changes that compensate for the low annual mileage. On a test ride, particular attention should be paid to any clonks or vague feedback from the front suspension, which could indicate dried or perished fork oil, and to the operation of the throttle bodies, which can suffer from fuel varnish accumulation and sluggish response after extended periods of inactivity.
