2012 Yamaha YP400 0.4L Petrol · RO12 NHV

A clear and uninterrupted run of passes from 2022 through 2025 establishes this Yamaha YP400 as a mechanically sound machine with no recorded advisories, defects, or failure items across the documented testing history. The same-day pass and fail entries on 6 August 2025 are a familiar MOT scenario where an initial fail on a minor presentation or quickly rectifiable item is followed immediately by a retest pass, and the absence of any defect entries on either record strongly suggests the motorcycle was brought back inside the testing window for a straightforward correction. With five consecutive passes and zero advisories on file, the structural, braking, lighting, and exhaust integrity of the machine has been independently verified on a consistent basis, which is the strongest possible indicator of roadworthiness for a fourteen-year-old motorcycle. Recorded mileage of 64,084 miles across fourteen years equates to roughly 4,577 miles annually, which is considerably below the typical accumulation rate for a commuter-class maxi-scooter of this vintage. The MOT history shows steady, near-annual testing with no multi-year gaps in the record, confirming the vehicle has remained in active service rather than being laid up or off the road for extended periods. This low but consistent usage profile generally means the engine and drivetrain have not been subjected to high-stress continuous running, which can preserve internal components, but it also places importance on routine items that degrade with age regardless of mileage, such as rubber seals, flexible brake lines, electrical connections, and battery condition. The complete absence of advisories suggests these ageing components have so far remained serviceable, though age-related wear should not be ruled out at this point in the motorcycle's life. For a prospective buyer, the inspection priorities should focus on confirming that the advisory-free MOT record genuinely reflects current condition rather than masking developing faults that have not yet crossed the failure threshold. On a test ride, pay particular attention to the feel of the front and rear braking systems, listening for any binding caliper drag, checking for pedal or lever sponginess, and inspecting the flexible brake hoses and any exposed metal brake pipes for surface rust or corrosion that could soon become an MOT failure. The suspension should be evaluated over uneven surfaces for knocking from the linkage, top yoke, or shock mounting points, and the rear swingarm pivot should be checked for any play that the static MOT test would not necessarily reveal. Steering should be smooth from lock to lock without notching or roughness, as low annual mileage combined with age can lead to dried or perished steering head bearings. Beyond the chassis items, a careful inspection of the Yamaha YP400 engine and ancillary systems is worthwhile given the age and modest mileage profile. Check for any signs of oil seepage around the engine casings, final drive area, and suspension linkages, as static rubber seals can harden and weep over time even on low-mileage machines. Inspect the exhaust system, particularly any mounting rubbers and downpipe joints, for corrosion or cracking that may have developed since the last MOT. Confirm that the cooling system, instruments, and electrical functions all operate correctly, and verify the condition and charge state of the battery, since infrequent riding over the years can leave a 12V battery operating below its optimal capacity. With a clean testing record and no documented defects, this YP400 presents as a well-maintained example, but a thorough physical inspection and test ride remain essential to confirm that the roadworthy condition verified at MOT continues to hold true today.
