2021 Honda NSS 125 AD-N 0.1L Petrol · AF71 YVR

The most recent DVSA MOT test on the 2021 Honda NSX 125 AD-N, conducted on 2026-09-01, resulted in a clean pass with no defects recorded. However, the vehicle’s MOT history reveals a concerning pattern of unresolved issues. The vehicle failed its 2025-05-15 MOT with a critical failure for the missing offside rear wheel fixing, alongside a repeated advisory for a loose rear mudguard. While the subsequent MOT in May 2026 passed, the unresolved wheel fixing issue—particularly the absence of a single fixing point—signifies a structural integrity concern that must be addressed before the vehicle achieves full roadworthiness. This failure suggests either a lack of prior repair or a failure of the repair itself, warranting immediate attention to prevent further damage to the wheel assembly or suspension geometry. The recorded mileage of 16,442 miles for a vehicle aged five years represents a notably low annual usage rate of approximately 3,288 miles per year. Such low mileage is unusual for a vehicle of this age and could imply prolonged periods of inactivity, particularly if the owner has not driven the motorcycle regularly. While low mileage can reduce wear on consumables like tyres, brakes, and fluids, it also raises concerns about potential issues arising from prolonged standing. For example, standing for extended periods can lead to brake disc corrosion, caliper binding, or fluid degradation in the hydraulic systems, as well as the development of rust within the suspension components or wheel bearings. Additionally, the absence of regular use may mean that the vehicle’s battery has not been charged frequently, potentially leading to a weakened or failing 12V battery over time. Given the MOT history’s unresolved structural concerns and the potential risks of prolonged standing, the prospective buyer should prioritise a thorough inspection of the rear wheel assembly and suspension. The missing wheel fixing must be repaired to restore the wheel’s secure attachment to the frame, and the suspension should be checked for signs of corrosion or excessive play, particularly around the rear wheel area. On a test drive, listen for unusual noises such as clunks or rattles from the rear suspension, and inspect the wheel alignment for any signs of misalignment or uneven tyre wear, which could indicate suspension or wheel assembly issues. The buyer should also verify the tyre condition, paying particular attention to sidewall perishing or cracking, which can weaken the tyre structure over time, even at low mileage. Additionally, check the brake system for any signs of corrosion on the discs or binding in the calipers, as standing can exacerbate these problems. If the buyer is concerned about the battery’s condition, they should test its charge and ensure it is securely mounted to prevent vibration-induced failure. For a vehicle of this age and mileage, particularly one that has not been driven regularly, the buyer should also schedule a professional service to assess the fluid levels and condition, including the brake fluid, coolant, and engine oil. Fluid degradation over time can lead to reduced performance and premature component failure. The buyer should also verify that the vehicle’s service book has been updated, as the Honda NSX 125 AD-N typically requires periodic maintenance such as valve adjustments, spark plug replacements, and chain tensioning. If the vehicle has been stored in a damp environment, it may benefit from a thorough inspection for rust on the frame, exhaust system, and other metal components. Finally, given the low mileage and potential standing-related issues, the buyer should consider a pre-purchase inspection by a qualified motorcycle mechanic to confirm the absence of hidden problems and ensure the vehicle is safe and reliable for use.
