1984 Yamaha DT50 0.0L Petrol · J812 LMW

The vehicle currently holds a valid MOT following a pass on 15 June 2026 at 24,615 miles. The maintenance trend shows signs of recent instability, as the vehicle failed a test just four days prior on 11 June 2026. While the most recent pass addressed the stop lamp switch and the carb leak, several minor defects from the failure persisted into the passing certificate. These included a damaged rear stop lamp, an insecure nearside rear direction indicator, distorted bead rims on both wheels, and a front tyre starting to perish. The recorded mileage of 24,615 miles is exceptionally low for a 1984 model, averaging roughly 586 miles per year. This pattern suggests the vehicle has spent significant periods stationary or has seen very light seasonal use. The data shows a notable jump of 1,149 miles between the June 2025 test and the June 2026 test, which is higher than the previous annual increment. This recent increase in usage, combined with the failure on 11 June 2026 for a stiff or notchy steering headbearing, indicates that the bike may be experiencing age-related degradation of components due to long periods of inactivity followed by sudden use. A prospective buyer should conduct a thorough physical inspection of the steering assembly and the fuel system. The failure regarding a leaking carburettor on 11 June 2026 suggests that seals or gaskets may be deteriorating due to age and fuel stagnation. The tester also flagged a stiff steering headbearing, which requires checking for smooth movement and potential bearing wear. Given the advisories regarding distorted bead rims and a perishing front tyre, a close examination of the wheel rims and the condition of all rubber components is necessary to ensure they are not suffering from dry rot or structural fatigue.
