2017 KTM 390 Duke 17 0.4L Petrol · WP67 WNW

The 2017 KTM 390 Duke presents a clean MOT history, with both recent tests—September 2022 at 8,555 miles and August 2021 at 8,450 miles—showing no defects or advisories. This indicates a stable maintenance trend, with no signs of recurring mechanical issues or deferred repairs. The absence of any failures or major advisories suggests the bike has been kept in good working order, though the limited MOT data leaves some components untested beyond basic compliance checks. The most recent test, just under four years ago, confirms the bike met all DVSA roadworthiness standards at the time, but the lack of subsequent testing raises questions about ongoing upkeep. The Duke’s mileage of 8,555 over nine years—roughly 950 miles annually—is exceptionally low for its age, even accounting for occasional storage or light use. Such minimal mileage typically reduces wear on consumables like tyres, brakes, and suspension, but it also means components may not have been exercised enough to reveal latent issues. The near-identical mileage between tests (just 105 miles apart over a year) suggests either prolonged storage or very infrequent riding, which could mask potential problems until they become acute. Without further MOT records, it’s impossible to confirm whether the bike has been consistently maintained outside of test intervals, but the current data points to a vehicle that has seen little use rather than one that has been neglected. For a buyer, the primary focus should be on components that degrade even with low mileage, such as rubber seals, suspension bushes, and brake fluid condition. The chain, sprockets, and clutch—critical on a Duke—should be inspected for wear, as these can deteriorate regardless of mileage if lubrication or adjustment has been inconsistent. Tyre condition, though not recorded in the MOT, is a key concern; given the bike’s age, even lightly used tyres may need replacement soon. Structural checks, including frame integrity and corrosion, are less likely to be issues on a relatively new model with minimal exposure, but any signs of rust or damage should be scrutinised. The absence of MOT advisories doesn’t guarantee hidden problems, so a pre-purchase inspection by a specialist—particularly for suspension geometry and brake function—is strongly advised.
