2000 Yamaha TRX850 0.8L Petrol · W371 AFV

The most recent MOT test on 10 June 2026 resulted in a pass, but the vehicle's recent history indicates a concerning downward trend in mechanical consistency. After a period of clean passes between 2019 and 2022, the vehicle has suffered two significant failures within the last two years. The transition from a clean record to failures involving brake efficiency and exhaust noise suggests that the vehicle may be experiencing age-related component fatigue or a lapse in preventative maintenance. With a recorded mileage of 20,867 miles over 26 years, this motorcycle has been used very sparingly, averaging approximately 803 miles per year. While this low mileage implies minimal wear on the internal engine components and gearbox, it introduces specific risks associated with long-term storage and infrequent use. Low-mileage vehicles often suffer from the degradation of perishable items such as seals, gaskets, and rubber hoses, which can perish due to age and lack of regular thermal cycling rather than physical wear. Prospective buyers should pay close attention to the recurring advisories regarding the exhaust and braking system. The repeated advisory for a noisy exhaust may indicate a developing leak at the manifold, a failing internal baffle, or structural corrosion within the silencer; listen for any rasping or irregular popping sounds during the test ride. Furthermore, the history of a binding rear brake and a failed roller brake test necessitates a thorough inspection of the rear braking assembly. Check the rear caliper for seized pistons, inspect the brake discs for uneven wear or heavy scoring, and ensure the caliper does not feel excessively hot after a short ride, which would indicate a binding issue. Given the vehicle's age and low usage profile, a physical inspection of age-related consumables is essential. Examine the tyre sidewalls for any signs of perishing, cracking, or dry rot, as tread depth alone is not a reliable indicator of safety on an older machine. Inspect all rubber components, including fuel lines, fork seals, and various vacuum hoses, for signs of hardening or cracking. It is also vital to verify that fluids such as brake fluid, coolant, and engine oil have been changed according to a calendar-based schedule rather than solely on mileage, as these fluids degrade over time. Finally, check for surface corrosion on the chain, sprockets, and brake discs, which often occurs when a vehicle sits stationary for extended periods.
