2004 Kawasaki ZX-9R 0.9L Petrol · WX04 AAZ

This Kawasaki ZX-9R passed its most recent MOT on 13 August 2024 at 19,267 miles, but the test confirmed a persistent exhaust noise issue (8.1.1 (a)) that has recurred in every inspection since July 2021. The trend is stable rather than worsening, as no new major defects have emerged, but the repeated noise advisory suggests either a poorly sealed exhaust system or a failing catalytic converter—both of which could escalate into more costly repairs if left unaddressed. The rear tyre tread was only flagged in 2021 and 2022, indicating it was replaced or repaired before the 2024 test, though the 2022 advisory still implies basic maintenance was deferred at some point. The vehicle’s mileage remains unusually low for its age, accumulating just 21 miles between the 2021 and 2022 tests and 20 miles between 2022 and 2024. This suggests prolonged periods of inactivity rather than regular use, which could mean components like the fuel system, battery, or even suspension bushes have deteriorated from lack of motion. The near-identical mileage across three tests also raises questions about odometer accuracy or whether the bike was stored rather than ridden. A buyer should prioritise a thorough inspection of the exhaust system, particularly the muffler and catalytic converter, as the persistent noise indicates a chronic issue. The suspension should be checked for dried or degraded bushes, especially if the bike has been stationary for extended periods, as this can accelerate wear. While the brakes appear to have been in order during the last test, the rear calipers or discs should be examined for uneven wear or binding, given the earlier tyre tread concerns. Finally, verify the battery health and fuel lines, as low mileage increases the risk of fuel system degradation or electrical component failure.
