1988 Yamaha DT125 0.1L Petrol · E165 AKW

The most recent DVSA MOT carried out on 14 February 2025 recorded a full pass with no defects noted, indicating that the motorcycle satisfied the statutory safety requirements at that time. With only a single MOT entry available, there is no trend of recurring failures or advisories to suggest a deteriorating condition; the absence of any recorded faults points to a stable maintenance status, at least as far as the mandatory checks are concerned. The recorded mileage of 14 585 miles spread over 38 years works out to an average of roughly 384 miles per annum, which is exceptionally low for a machine of this vintage. Such limited use often implies long periods of storage rather than continuous riding, and while it reduces wear on wear‑items such as brake pads, clutch plates and tyre tread, it also raises the likelihood of age‑related degradation of rubber components, seals, and metal corrosion. A sudden increase in mileage after a prolonged lull would place additional stress on the engine, transmission and suspension, so any recent surge in use should be examined carefully. Prospective buyers should give particular attention to the condition of the tyres, which may have perished despite low tread wear; inspect the sidewalls for cracking, dry rot and hardening, and verify that the tread depth complies with legal limits. The 12‑volt battery, if original, is almost certainly beyond its service life and should be tested for cranking voltage or replaced outright. Because the motorcycle has likely spent considerable time idle, all fluid reservoirs merit scrutiny: check the engine oil for milky appearance or sludge, replace it if the last change is unknown, and consider a fresh change of brake fluid and fork oil to guard against moisture‑induced corrosion. Examine the fuel tank, petcock and carburettor for rust, sediment or stale fuel residues, and ensure the fuel lines are supple rather than brittle. On a test ride, listen for any abnormal noises such as clunking from the rear suspension bushings, loosened rear swingarm bearings or worn chain tensioners, and feel for any irregularities in the throttle response that could indicate carburettor or ignition wear. Verify that the clutch engages smoothly without judder, that the brakes apply firmly without sponginess or excessive pedal travel, and that the rear brake does not exhibit uneven drag. Finally, inspect the frame and exhaust for signs of rust or fatigue, and confirm that the chain is correctly tensioned, well‑lubricated and that the sprockets show even wear. Addressing these age‑related checks will give a clearer picture of the motorcycle’s true roadworthiness beyond the clean MOT record.
