1981 Honda CB250 N 0.2L Petrol · CGK 587X

A motorcycle of this vintage and specification with a completely clean MOT history spanning the most recent three annual tests represents a notably well-maintained example. Each test, from January 2022 through January 2024, returned a pass with no advisories or defects recorded, and the most recent assessment on 26 January 2024 again produced a clean pass. For a 1981 Honda CB250N, a twin-cylinder commuter machine now over four decades old, this absence of advisories across three consecutive tests is a strong indicator of structural integrity, particularly given the propensity of older Honda motorcycles to develop corrosion on the frame, swingarm, and mounting brackets. While the absence of recorded advisories does not guarantee perfection, it does demonstrate that the items typically scrutinised under the new MOT categories for older bikes including lighting, braking efficiency, tyre condition, exhaust integrity, and structural corrosion have all been found compliant at each recent examination. The recorded mileage of 52,431 miles against a manufacturing date of 1981 yields an annual average of approximately 1,165 miles, which is exceptionally low for a motorcycle of this era. Such restrained usage is consistent with a machine that has spent considerable periods laid up rather than in active service, and it raises legitimate mechanical considerations that sit outside the MOT record. The two-stroke derived CB250N platform, though actually a four-stroke twin, is mechanically robust, but prolonged standing periods commonly bring degradation of carburettor internals, fuel varnish accumulation, oxidation within the fuel tank, hardening of rubber components such as fork seals, vacuum hoses, and drive chain O-rings, and electrolyte loss in the battery. The MOT history does not flag any such deterioration, but a motorcycle that has averaged fewer than fifty miles per week across its lifetime warrants thorough inspection of these ageing rubber and fluid systems before purchase. A pre-purchase inspection should therefore focus on the items most likely to deteriorate with age rather than mileage. The carburettors on the CB250N are particularly susceptible to pilot jet blockage after standing, so listen for uneven idle, hesitation on initial throttle application, or a persistent misfire when cold. Check the fuel tank internally if possible, or at minimum inspect the fuel filter for rust debris, and verify that the vacuum petcock diaphragm is functioning correctly. The front fork oil and seals should be examined for weeping or pitting on the stanchions, as fork seals typically harden with age and begin to leak once disturbed. The rear shock absorbers, given the bike's age, should be assessed for damping effectiveness, and the swingarm pivot and suspension linkages physically checked for play, as these are common sources of advisories on older Honda twins even when not yet flagged. On a test ride, pay particular attention to the braking system, including the front disc for any lipping or warping that could produce lever pulsation, and the rear drum for binding or inadequate release, both of which can manifest as uneven deceleration or excessive lever travel. The drive chain and sprockets warrant close scrutiny given the age of the drivetrain components, with any hooked sprocket teeth or stiff chain links indicating replacement is due. Listen for engine bottom-end or top-end mechanical noise that could suggest camshaft or valve train wear, and verify that the electric start and charging system function correctly with a healthy battery, as voltage regulation issues are common on machines of this vintage. Finally, inspect the frame, headstock bearing area, and rear subframe mounting points for any surface corrosion bubbling beneath paintwork, as even a clean MOT record does not preclude the onset of cosmetic or early structural oxidation that has not yet reached the threshold for advisory notation.
