1991 Yamaha TDM850 0.8L Petrol · J808 GCX

The 1991 Yamaha TDM850 is currently roadworthy but exhibits recurring minor issues that suggest inconsistent maintenance. The most recent 2024-10-17 MOT confirmed a pass, though it flagged a noisy exhaust (8.1.1 (a)), rear brake pads near minimum (1.1.13 (a)), and a slightly loose drive chain (6.1.7 (c) (i)). These align with prior findings, such as the 2023-07-12 exhaust noise and 2022-06-18 tyre wear, indicating a stable pattern of minor faults rather than worsening conditions. No critical structural or safety risks were recorded in the latest test, but the persistence of issues like brake pad limits and chain tension warrants attention. The vehicle’s mileage of 42,566 miles over 35 years equates to approximately 1,216 miles annually, a low figure that may reflect infrequent use or prolonged inactivity. MOT records show a gap of 13 months between the 2021-06-19 test and the next in 2022-06-18, during which a front tyre failure and brake light defect were recorded. Subsequent tests in 2022 and 2023 addressed these, with no major discrepancies in the intervening years. The sparse data suggests a lack of regular servicing, though no significant mechanical degradation has been documented. A buyer should inspect the tyres for uneven wear, the exhaust system for leaks or corrosion, and the rear brakes for pad thickness and caliper binding. The drive chain’s tension and the front steering head bearing’s stiffness, noted in 2021, require verification. While no structural rust or suspension bush failure was recorded, the low mileage and sporadic testing history mean hidden issues—such as seized components or degraded fluids—could exist. Regular maintenance is advised to address the recurring minor faults and ensure long-term reliability.
