2009 Triumph Thruxton 0.9L Petrol · P22 ECT

The most recent MOT test on the Triumph Thruxton, conducted on 2026-06-19, resulted in a pass with two advisories: a drive chain that is slightly tight, classified under 6.1.7 (k) (i), and a front brake system showing minor fluctuation in brake effort, noted under 1.2.1 (e). While this is a positive outcome, the vehicle’s MOT history reveals a pattern of recurring issues that warrant closer attention. Notably, the rear direction indicators have consistently failed or been incorrectly positioned in prior tests, with the most recent failure in 2026-06-18 and a prior major failure in 2025-05-02, indicating a potential mechanical or wiring problem that may require professional investigation. Additionally, the stop lamp failure in 2023-04-20, classified as dangerous, suggests a persistent electrical or wiring fault that could compromise braking reliability if not addressed. These recurring advisories and failures suggest that while the vehicle is currently roadworthy, there are underlying issues that may escalate without proactive maintenance, particularly in the electrical and mechanical systems affecting visibility and braking. The recorded mileage of 13,020 miles for a vehicle aged approximately 17 years represents a remarkably low annual usage rate of around 766 miles per year, which is unusually low for its age and likely indicative of either infrequent operation or prolonged periods of inactivity. Such low mileage can mask wear and tear on consumables like brake pads, tyres, and fluids, as well as potential issues arising from standing, such as corrosion in brake systems, binding calipers, or fluid degradation due to stagnation. However, it also raises concerns about the vehicle’s exposure to environmental factors, including exposure to moisture, temperature extremes, or lack of regular servicing, which can accelerate wear in non-consumable components like the drive chain, suspension, and electrical systems. The drive chain’s tightness noted in recent advisories may be exacerbated by prolonged inactivity, leading to increased stress on the transmission and potential long-term damage if not serviced promptly. For a prospective buyer, the first priority is to verify the electrical system’s integrity, particularly the stop lamps, rear indicators, and wiring harnesses, as these failures have been persistent and could indicate a failing fuse, relay, or sensor. During a test drive, listen for any irregularities in the brake system, such as uneven pedal feel, vibration, or grinding noises, which could signal binding calipers, warped brake discs, or hydraulic issues. The drive chain’s tightness should be confirmed by checking for excessive slack or unusual noises when accelerating, particularly from the rear wheel area. Inspect the rear indicators for proper alignment and functionality, ensuring they are spaced correctly and illuminate independently. Given the low mileage, the vehicle’s tyres should be examined for sidewall perishing, which can occur from age alone, even without significant wear. Check for cracks, delamination, or dry rot, as these can compromise tyre integrity and safety. Beyond the MOT findings, a thorough physical inspection is essential. The suspension should be checked for signs of wear or damage, including worn suspension bushes, cracked coil springs, or excessive play in the steering. The brake system should be inspected for corrosion on brake discs, particularly if the vehicle has been stationary for extended periods, as this can lead to binding or reduced braking efficiency. The fluid levels, including brake fluid, coolant, and engine oil, should be checked for freshness, as fluids degrade over time even with low mileage. Given the age of the vehicle, the 12V battery should be tested for charge capacity and terminal cleanliness, as standing can accelerate battery failure. If possible, obtain a service history to confirm that routine maintenance, such as oil changes, filter replacements, and fluid top-ups, has been conducted at recommended intervals. Finally, a professional inspection by a qualified Triumph specialist may be advisable to address the recurring electrical and mechanical issues, ensuring the vehicle’s long-term reliability and roadworthiness.
