2015 Triumph Thruxton 0.9L Petrol · YS64 OJO

Recurring issues with the drive chain and a recent exhaust advisory define the mechanical profile of this vehicle, which most recently passed its MOT on 15 May 2026. The record shows a cyclical pattern regarding the drive chain, with a failure in May 2025 due to excessive wear and looseness, preceded by an advisory for looseness in April 2024, and an earlier failure in March 2023 for the same issue. While the drive chain defects appear to have been addressed following the 2025 failure, the latest test result introduces a new advisory regarding a noisy exhaust, suggesting a potential change in the exhaust system's integrity or mounting. The recorded mileage of 17,440 miles over an eleven-year period represents a low annual accumulation of approximately 1,585 miles. This usage pattern suggests the vehicle has spent significant periods stationary or has been used only for infrequent, short-distance trips. Mechanically, such low usage can mean that while drivetrain components like the engine and gearbox may have relatively low wear, other elements such as rubber seals, hoses, and tyres may be subject to age-related degradation rather than mileage-related wear. The gaps in testing between 2021 and 2023 also reflect periods where the vehicle was not undergoing regular official inspections. A prospective buyer should focus heavily on the drive chain and sprocket assembly during a physical inspection to ensure the recent replacements have been fitted correctly and are not showing premature wear. On a test ride, listen for any irregular slapping or rattling sounds from the chain area, especially under acceleration or when decelerating, which could indicate improper tension or alignment. Given the recent advisory for a noisy exhaust, pay close attention to the sound profile of the engine; listen for any unusual rasping, popping, or increased decibel levels that might suggest a leak at the manifold, a loose heat shield, or a compromised exhaust connection. Further inspection should involve checking the exhaust mounting points and brackets for any signs of loosening or vibration, as this often correlates with noise advisories. Because the vehicle has been used sparingly, it is also prudent to inspect the condition of all rubber components and fluid levels to ensure that long periods of inactivity have not led to drying or seepage. Ensure that the exhaust note remains consistent across the rev range and does not change significantly when the engine reaches operating temperature, which could indicate an intermittent exhaust leak.
