2004 Kawasaki Z1000 1.0L Petrol · WX04 AAV

The most recent MOT test on 2026-06-17 confirms the vehicle remains roadworthy, though it carries a persistent advisory for an exhaust noise issue—first recorded in June 2023 and repeated in the latest test. This suggests the problem has not been addressed despite two consecutive failures, indicating either neglect or a recurring mechanical fault. The advisory alone does not invalidate the MOT pass, but it signals a clear maintenance oversight. No other advisories or failings appear in the record, which is unusual given the vehicle’s age, implying either a well-maintained example or a lack of thorough inspection beyond the MOT’s scope. The recorded mileage of 13,174 miles over 22 years—approximately 599 miles annually—is exceptionally low for a motorcycle of this vintage. The gap between tests, spanning nearly three years (from June 2023 to June 2026), further suggests the bike has likely been stored or used minimally. Such low mileage can mask deeper issues, as components like suspension bushes, throttle cables, and fuel system seals may degrade from prolonged inactivity rather than wear. The absence of intermediate maintenance records raises questions about whether routine services (chain tension, valve adjustments, or fluid changes) were performed, which are critical for two-stroke or high-revving engines like the Z1000’s. A buyer should prioritise an immediate inspection of the exhaust system, particularly the rear section, as the recurring noise advisory implies either a leak, loose mounting, or failing muffler. The noise classification (8.1.1 (a)) typically points to excessive decibel levels, which could indicate a cracked or perforated section. Given the low mileage, the suspension—including coil springs, bushings, and fork seals—should be scrutinised for dry rot or perished rubber, as these components degrade over time even with minimal use. The brakes, while not explicitly failed, warrant checking for binding calipers, uneven pad wear, or corrosion on the rotor surfaces, especially if the bike has been stored in damp conditions. Finally, the electrical system, including wiring harnesses and connectors, should be inspected for signs of oxidation or fraying, as prolonged disuse can accelerate degradation.
