2001 Yamaha DT125 0.1L Petrol · FJ51 GAU

The maintenance trend for this 2001 Yamaha DT125 remains stable, with the most recent MOT on 18 July 2025 at 12,190 miles passing without any defects. A duplicate entry on the same date records a failure with no listed defects, indicating an aborted test or administrative anomaly rather than a mechanical fault. The motorcycle currently presents a clean bill of health, showing no recurring mechanical or structural issues across the recorded history. The mileage accumulation is exceptionally low for a machine of this age, averaging roughly 488 miles per year. Between the September 2022 test at 11,763 miles and the December 2023 test at 11,849 miles, the motorcycle covered just 86 miles over fifteen months. The subsequent jump to 12,190 miles by July 2025 represents only 341 miles in eighteen months. Such minimal usage strongly suggests prolonged periods of standing rather than consistent riding. Despite the clean MOT record, a buyer must inspect the physical consequences of long-term storage. Check the tyre sidewalls for perishing and cracking, as rubber degrades with age and lack of use regardless of tread depth. Examine the exhaust system for internal corrosion and verify that the brake calipers have not seized due to moisture ingress during standing periods. The suspension linkage and swingarm pivot points require close scrutiny for dried-out grease and surface rust. Given the DT125's off-road heritage, assess the frame around the steering head and engine mounts for cracks or structural corrosion that might only manifest under off-road stress. The carburettor will almost certainly require cleaning or rebuilding if stale fuel has sat in the float bowl. A cold start is essential to verify smooth idle and check for smoke indicating perished valve stem seals.
