1980 HONDA CB400N0.4L Petrol

This Honda CB400N passed its most recent MOT test on 15 May 2023 with no defects recorded, confirming it remains roadworthy under current DVSA standards. The absence of advisories or failures in either of the two most recent tests—2023 and 2022—suggests a stable maintenance history over the past three years. However, the vehicle’s age (46 years) and low mileage (24,308 miles) necessitate an in-person inspection to verify long-term structural integrity, as MOT tests do not fully assess wear beyond visible defects. The recorded mileage indicates an exceptionally low annual average of approximately 528 miles, which is consistent with minimal use or prolonged storage. The gap between tests—1,852 miles in 13 months (May 2022 to May 2023)—does not suggest aggressive driving, but it also raises questions about whether critical components like chain tensioners, suspension bushes, or throttle cables have been serviced regularly. Without intermediate maintenance records, there is no way to confirm whether routine checks were performed between MOTs. Given the vehicle’s vintage, a buyer should prioritise inspecting the chain and sprocket for excessive wear or stretch, as these are not routinely covered by MOT tests. The suspension—particularly coil springs, fork seals, and rear swingarm bushes—should be checked for dry rot or corrosion, especially if the bike has spent extended periods stationary. Brake pads and discs, while not failed in MOTs, may require evaluation for uneven wear or glazing, and the exhaust system should be examined for leaks or structural fatigue. Rust penetration in the frame or fuel tank is another critical area, as it can compromise structural integrity without obvious external signs.
