Mechanical Assessment

AI-generated interpretation of this vehicle’s MOT record — not an official statement and not a substitute for an independent inspection.

The vehicle presents a stable roadworthiness status with a clean record as of the most recent inspection. The latest MOT conducted on 10 May 2022 at 1,927 miles passed with no defects recorded, indicating that the mechanical and safety concerns identified in previous years have been addressed. This progression suggests the motorcycle has been maintained to a high standard during its recent operational life despite its age. The mileage pattern is exceptionally low for a 49-year-old machine, averaging approximately 39 miles per year. There is a significant nine-year gap between the July 2013 test at 1,862 miles and the May 2022 test, where it only covered an additional 65 miles. This minimal usage suggests the bike spends long periods in storage rather than being subjected to regular commuting. While low mileage reduces wear on the drivetrain and engine, it often leads to the degradation of rubber-based components and fluids which do not reflect on mileage alone. A buyer must prioritize a physical inspection of the rubber components and structural integrity due to the age. The 2013 test at 1,862 miles flagged deterioration across all four rear suspension bushes, and while these were not excessive at the time, rubber is prone to drying and cracking over decades of inactivity. The 2010 failure noted a cracked front tyre sidewall and a distorted bead rim, highlighting the risk of age-related failure regardless of tread depth. Check the exhaust mountings and wiring loom for corrosion and ensure that the 2010 electrical faults, such as the rear position lamp, have not returned due to corrosion or perished insulation.
