1977 Yamaha RD400 0.4L Petrol · UND 785S

The vehicle maintains a stable roadworthiness status, evidenced by a consistent history of MOT passes. The most recent test on 17 March 2025 at 8,283 miles resulted in no defects or advisories, mirroring the trend of clean records spanning the last decade. This consistency suggests the motorcycle has been maintained to a standard that avoids the mechanical or structural failures typically seen in older machinery. The mileage pattern is exceptionally low for a 49-year-old vehicle, averaging approximately 169 miles per year. Between May 2015 and 2018, the bike covered only 1,136 miles, indicating it was used sporadically or stored for long periods. A notable gap exists between May 2018 and March 2025, during which only 838 miles were recorded over seven years. While this low mileage reduces mechanical wear on the drivetrain and engine, long periods of standing often lead to the degradation of rubber-based components rather than mechanical friction. A buyer must conduct a physical inspection focused on components that suffer from age rather than mileage. Low-mileage vintage motorcycles often exhibit dry rot in fuel lines, perished fork seals, and seized brake calipers due to inactivity. The structural integrity of the frame should be checked for hidden corrosion, as the MOT records do not detail surface-level rust issues. Verify the age of the tyres and the condition of the suspension bushings, as rubber loses its structural properties over decades regardless of tread depth.
