2021 KTM 390 Adventure 21 0.4L Petrol · FD21 ACF

The most recent MOT carried out on 14 August 2025 returned a Pass with no recorded defects, following an earlier Pass on 1 June 2024 that also showed a clean sheet. With two consecutive years of fault‑free examinations, the maintenance record appears stable and there are no indications of deteriorating components or emerging safety concerns from the official testing side. The odometer reads 10,418 miles on a model that entered service in 2021, giving an average of roughly 2,000 miles per annum. This is considerably below the typical usage pattern for a 390 cc adventure motorcycle and suggests either predominantly short‑haul riding or extended periods of storage. Low annual mileage reduces wear on consumables such as brake pads, tyres and the chain, but prolonged inactivity can accelerate the ageing of rubber compounds, battery electrolyte, and cause corrosion on metal parts that are not regularly exercised. For a prospective buyer the first visual inspection should focus on tyre condition; even with limited wear the sidewalls can develop dry‑rot, cracking or hardening after five years, and the tread depth should still be at least 1 mm. Examine the 12‑volt battery for signs of sulfation – swollen case, leaked electrolyte or a voltage below 12.5 V after a short idle – and consider a load test. The brake discs and pads merit close scrutiny: surface rust is common after sitting, but excessive pitting or uneven pad wear may indicate sticking calipers that will need cleaning or re‑bleeding of the hydraulic system. Check the chain and sprockets for proper tension, lubrication and any “shark‑tooth” wear, as chain life is heavily dependent on regular cleaning and oiling. During a test ride listen for any clunk or knock from the front suspension, which could reveal deteriorated fork seals or worn bushings, and feel for smooth throttle response without hesitation, which would point to a healthy fuel injection system and spark plug condition. Verify that the clutch engages cleanly without drag, that gear shifts are crisp, and that the engine idles steadily without excessive vibration. Finally, confirm that the service book contains entries for the recommended 6‑month or 6 000‑mile intervals, especially oil changes and coolant flushes, as time‑based maintenance is critical on a liquid‑cooled adventure bike that may have spent long periods idle.
