2006 Yamaha XT 660 X 0.7L Petrol · AV06 RYB

The latest MOT test on 9 September 2023 resulted in a pass with no recorded defects, following a prior failure on the same date with no listed issues, which may indicate an administrative anomaly rather than a mechanical concern. The preceding test on 20 September 2022 also passed without defects. This suggests a stable maintenance trend, with no recurring failures or advisories in the available history, implying the motorcycle has been kept in a roadworthy condition in recent years. At 20 years old with 43,415 miles, the annual average of approximately 2,171 miles is low for a motorcycle of this age. Such usage patterns often point to intermittent riding or prolonged periods of storage, which can lead to degradation from standing rather than wear from high mileage. Components like tyres, brake discs, and seals may suffer from age-related deterioration, while fluids and the battery can degrade due to inactivity. Given the clean MOT history and low mileage, a thorough physical inspection is essential. Check the tyres for sidewall cracking or perishing, as rubber compounds harden with age regardless of tread depth. Examine the brake discs for surface corrosion or pitting, and test for binding calipers, which can occur after extended periods of disuse. Inspect the chain and sprockets for rust, stiffness, or excessive wear, as these are often overlooked during low-mileage storage. Additionally, verify the condition of the 12V battery, as prolonged inactivity can lead to sulphation and reduced capacity. Finally, assess the motorcycle’s fluids, including engine oil, brake fluid, and coolant, as these degrade over time even with minimal use. Look for signs of leakage or contamination, and confirm that service intervals have been adhered to, particularly for the valve clearances and timing chain, which are critical on this model. A test ride should reveal any stiffness in the suspension, unusual noises from the drivetrain, or hesitation in the fuel system, all of which can indicate neglected maintenance despite the low recorded mileage.
