1989 Yamaha DT125 0.1L Petrol · G395 WLL

The most recent DVSA MOT, conducted on 30 July 2026, resulted in a full pass with no recorded defects or advisories. With only a single MOT entry available, it is not possible to identify a trend over time, but the absence of any failures suggests that, at the time of testing, the motorcycle met the statutory safety and emissions requirements. The recorded mileage of 28 162 mi on a 1989 model equates to an average of roughly 760 mi per year, which is markedly low for a machine of this age. Such limited annual usage often indicates that the bike has spent considerable periods in storage or has been ridden only occasionally. Low mileage reduces cumulative wear on consumables such as brake pads, tyres and clutch plates, but it also raises the likelihood of age‑related deterioration in components that are not mileage‑dependent, for example rubber seals, fuel lines and electrical connections. For a prospective buyer the first visual inspection should focus on the condition of the tyres; even if tread depth is acceptable, sidewalls may show cracking, dry rot or hardening due to prolonged exposure to the elements. Examine the tyre pressure retention over a short period and look for any bulges that could signal internal damage. The 12 V battery, if original, is likely beyond its useful life and should be tested for cranking voltage and capacity, or replaced pre‑emptively. Check all visible rubber hoses, fuel lines, and the carburettor float bowl for signs of brittleness, cracking or fuel leakage, as aged elastomers can cause fuel starvation or flooding. Corrosion on the frame, especially around the rear sub‑frame and swing‑arm pivots, should be inspected; any rust that has penetrated the metal may compromise structural integrity. The braking system warrants a thorough functional check: inspect the front and rear brake discs for surface rust, scoring or glazing, and verify that the pads have sufficient material left. Test the hand‑brake for firm engagement and listen for any uneven pull or squeal that could indicate seized caliper pistons or worn pads. The suspension should be examined for cracked or perished fork seals, oil leakage and the condition of the rear shock absorber bushings; a clunk or excessive dive under braking may reveal worn bushings or loss of damping. Finally, confirm that the engine oil has been changed at appropriate intervals, examine the spark plug for fouling or wear, and, if possible, review any service book stamps to corroborate regular maintenance. A short test ride listening for irregular idling, hesitation on acceleration, or abnormal exhaust smoke will help reveal any hidden issues before committing to purchase.
