1991 Kawasaki KDX125 0.1L Petrol · H658 FLU

The most recent DVSA MOT, dated 11 July 2025, recorded a pass but also a failure for headlamp aim being too low (4.1.2 (a)). Apart from that isolated lighting issue, the test history shows no major defects, only recurring advisories concerning tyre tread depth and a non‑functioning indicator warning light. Over the past decade the pattern has been essentially stable, with minor wear items flagged but no deterioration in core mechanical systems, suggesting the bike has been kept in reasonable order. With a recorded 12 326 miles on a 1991 model, the average annual mileage works out at roughly 350 miles per year – an exceptionally low utilisation for a thirty‑five‑year‑old motorcycle. Such low usage typically points to long periods of storage or very light riding, which can be as detrimental as high mileage because rubber compounds, seals and metal components age even when not in motion. The sparse mileage also means that consumables such as tyres, brake pads and fluids are likely to have exceeded their service life despite the low distance covered. Prospective buyers should give particular attention to the lighting system, confirming that both headlamps can be correctly adjusted to the legal aim and that the indicator warning light functions reliably; a mis‑aimed headlamp will impair night riding and may be symptomatic of a misaligned fork or worn steering head bearings. The tyre advisories from 2018 and 2019 indicate that both front and rear tyres were close to the legal tread limit at that time, so a visual inspection for tread depth, sidewall cracking, dry rot and uneven wear is essential – any tyre that shows age‑related perishing or insufficient tread must be replaced before the next MOT. Brake performance should be checked for any shudder, pulling or reduced lever feel, which could reveal corroded discs, seized calipers or worn pads that have not been refreshed due to the bike’s infrequent use. Beyond the recorded issues, a thorough age‑related inspection is advisable. Examine the frame, swing‑arm and exhaust for corrosion, especially in the under‑body and mounting points where standing moisture can accumulate. Test the 12 V battery voltage and load capacity, as batteries on low‑use machines often suffer from sulphation and may need replacement. Verify that engine oil, coolant (if fitted) and brake fluid have been changed in line with calendar intervals rather than mileage, looking for signs of moisture ingress, sludge or loss of viscosity. Finally, inspect the suspension bushes, coil springs and fork seals for cracks, leakage or excessive play, and listen for any clunking or knocking while rolling the bike over bumps – any of these symptoms could indicate wear that has progressed unnoticed during long storage periods.
