1990 Yamaha XJ 600 0.6L Petrol · G147 SLG

The most recent MOT on 21 June 2025 at 18,429 miles recorded a Pass with no defects, confirming that the motorcycle remains roadworthy. The uninterrupted sequence of passes from 2019 through 2025 indicates a stable maintenance pattern, with no emerging deterioration evident in the official test results. Across a 36‑year lifespan the bike has logged just 18,429 miles, averaging roughly 512 miles per year. Between the 17 June 2023 test at 17,780 miles and the 3 June 2024 test at 17,867 miles the increase was only 87 miles, and the subsequent rise to 18,429 miles by June 2025 adds 562 miles in a year – all well within low‑usage parameters. No sudden mileage spikes appear; the record is consistently sparse, suggesting limited exposure rather than heavy wear. Although the MOT history shows no recorded faults, a prospective buyer should still examine key wear items. Verify tyre tread depth and sidewall condition, as low‑mileage machines can still suffer from age‑related cracking. Inspect the drive chain, sprockets, and tensioner for stretch or corrosion, and confirm that the clutch plates engage smoothly. Check the front and rear suspension bushes and coil springs for any play or oil leakage, and assess brake discs and pads for uneven wear or glazing. A visual survey for frame rust, especially around the engine mounts and swingarm, will reveal any hidden structural corrosion that the MOT may not have flagged. Finally, confirm that exhaust emissions remain within legal limits and that the lighting, horn, and registration plates function correctly. A brief road test to listen for abnormal noises from the engine, gearbox, or rear suspension will help ensure that the motorcycle’s mechanical integrity matches the clean MOT record.
