1981 Yamaha XS400 0.4L Petrol · SLD 128W

The roadworthiness of this Yamaha XS400 remains difficult to verify due to the significant absence of recent MOT data. The last recorded test occurred on 16 November 2021, meaning the machine has operated without a formal inspection for nearly five years. While the 2021 pass indicates the motorcycle met safety standards at that time, the lack of subsequent testing makes it impossible to determine if the mechanical condition has remained stable or deteriorated during this extended period of inactivity. The recorded mileage of 21,288 miles over forty-five years averages out to approximately 473 miles annually, a figure that suggests long intervals of storage rather than consistent use. The failed test on 13 November 2021, followed immediately by a pass three days later, implies a minor administrative or easily rectified issue rather than a systemic mechanical failure. However, the sparsity of the data provides no insight into the current state of the engine, electrical system, or rubber components, which are prone to degradation regardless of low mileage. Prospective buyers must prioritise a comprehensive physical inspection of all perishables. Long-term storage often leads to fuel system contamination, perished fork seals, and seized brake calipers, none of which are captured in the limited MOT history provided. The structural integrity of the frame and the condition of the exhaust system require close scrutiny for corrosion, as the bike has likely spent significant time stationary in environments that may have compromised its metalwork. You should verify the operation of all lighting and ensure the tyres have not developed flat spots or sidewall cracking before attempting to return this motorcycle to the road.
