YAMAHA TDM8501999 · 0.8L Petrol

The Yamaha TDM850 presents as roadworthy based on the most recent test conducted on 16 June 2025 at 7,814 miles, where the tester recorded a pass with no defects. The maintenance trend is stable, showing four successive clean passes from 2023 through 2025 after an anomalous failure on 15 July 2022 at 7,751 miles that also listed no defects. That same-day fail-and-pass points to a paperwork or presentation anomaly rather than a mechanical deficiency. Mileage data reveals exceptionally low use for a 27-year-old machine. Between the July 2022 test at 7,751 miles and the June 2025 test at 7,814 miles, the odometer advanced only 63 miles across three years. Annual examinations continued without gap, yet the roughly 289 miles per year average confirms the bike spent long periods stationary. Such a pattern often reflects careful seasonal riding but invites degradation from storage. A buyer should still commission a physical inspection focused on inactivity-related wear. The MOT records show no advisories on suspension, brakes, or structural corrosion, but aged fork seals, swinging-arm bearings, and caliper pistons can stiffen or leak without regular movement. Examine tyre sidewalls for cracking and check brake discs for surface rust pitting. Verify exhaust mounts and frame welds for hidden corrosion that a static test might miss. The keeper clearly kept the TDM850 to a passable standard each summer, yet the 2022 duplicate entry suggests loose administrative control rather than skipped consumable upkeep. Given the minimal annual mileage, prioritise fresh fluids, brake line condition, and tyre replacement if date codes exceed five years.
