2005 Yamaha XT660X 0.7L Petrol · OU55 DWK

A notably lean MOT dossier accompanies this 2005 Yamaha XT660X, with every recorded test between 2022 and 2025 resulting in a pass and zero defects logged against the machine. Across four passes and a single administrative failure on 27 April 2024 that returned no advisories or component failures, the motorcycle has presented a consistent record of roadworthy condition throughout its documented testing life. The most recent pass on 25 April 2025 reinforces a stable and untroubled pattern, with no wear items, corrosion, lighting concerns, braking defects, or structural issues flagged at any stage. For a single-cylinder supermoto of this age, the absence of chronic advisories relating to fork seals, swingarm bearings, chain and sprocket wear, or brake component deterioration is a positive indicator, though it should be noted that MOT testing for motorcycles primarily addresses safety-critical items rather than broader mechanical condition. With 33,715 miles spread across roughly 21 years, annual usage works out at approximately 1,605 miles, which is well below typical commuter levels for this class of machine. Testing intervals have remained broadly consistent on an annual basis, with no multi-year gaps that would suggest prolonged storage. However, low annual mileage on a carburetted or fuel-injected single-cylinder motorcycle of this vintage brings its own considerations, particularly around standing starts after periods of inactivity, rubber component perishing in suspension linkages and brake calipers, and potential corrosion in less frequently refreshed areas such as the exhaust system, fasteners, and electrical connectors. The mileage progression should be verified against the V5 and service documentation to confirm the figure is genuine rather than a stalled odometer reading. From a buyer inspection standpoint, the absence of recorded advisories means attention must focus on items the MOT does not cover in detail. A careful visual and physical examination should prioritise the swinging arm pivot bearings, rear shock linkage bearings, and headstock bearings for any notchiness or play, as these are common wear points on XT660X machines of this age. Brake calipers, particularly the front, should be checked for binding pistons and corroded slide pins, while the brake discs warrant inspection for warping and minimum thickness, especially given the low annual mileage which can lead to surface corrosion on discs that see limited use. On the test ride, listen for clutch slip under load, any misfire or hesitation from the fuel injection or carburation, and confirm the gearbox selects cleanly through all ratios without false neutrals. Tyre condition warrants close scrutiny, as low-mileage motorcycles often present with aged rubber that has hardened and cracked despite retaining legal tread depth, and the original-equipment size should be confirmed against the current fitment. The chain and sprocket set should be examined for stretched chain, hooked sprocket teeth, and adequate slack adjustment, with particular attention to the front sprocket cover area where wear debris accumulates. The exhaust system, particularly the downpipe and silencer mounting, should be inspected for internal corrosion and security, while all electrical functions including indicators, headlamp main and dipped beam, horn, and instrument illumination must be confirmed operational. Given the clean MOT record but modest annual mileage, a thorough pre-purchase inspection by a motorcycle specialist familiar with the XT660X platform would be money well spent, focusing on the areas the annual test simply does not reach.
