2010 Yamaha XT 660 X 0.7L Petrol · EA60 XFF

The 2010 Yamaha XT660X presents a stable and improving maintenance picture in its most recent records. The March 2025 test at 27,277 miles returned a clean pass with zero defects, which is a positive shift from the previous two years where testers flagged minor suspension oil misting. This suggests the rear shock absorber leak noted in March 2024 has either been repaired or has not worsened to the point of failure. The overall trend is one of resolution rather than deterioration. The mileage pattern tells a story of very light use. The bike has covered roughly 1,705 miles per year over its sixteen-year life, which is exceptionally low for a dual-sport machine. Between the April 2023 test at 24,856 miles and the March 2025 test at 27,277 miles, it added just 2,421 miles over nearly two years. There are no alarming gaps or sudden spikes in accumulation, and the record is clean enough to suggest consistent, if minimal, annual use rather than long periods of neglect punctuated by heavy riding. The recurring advisory theme across this history is suspension degradation. Both the nearside front and rear shock absorbers have shown light oil misting in separate tests, a condition that points to worn seals rather than catastrophic failure. On a bike this age, even with low mileage, perished rubber bushings and dried fork seals are common culprits. A prospective buyer should compress the front and rear suspension by hand, checking for smooth rebound damping and any signs of fresh oil weeping from the stanchions or shock body. Beyond the suspension, the 2023 advisory for a nearside front tyre worn close to the legal limit is worth noting. Failing on tyre tread at relatively low mileage suggests the previous owner may have skipped basic consumable replacements during periods of infrequent use. Inspect all rubber components carefully, including brake hoses and gaiters, for age-related cracking. The clean 2025 result is encouraging, but a low-mileage bike of this vintage demands a close physical inspection of corrosion on the frame, subframe, and fastener points, particularly around the rear shock linkage and swingarm pivot where standing moisture can cause hidden pitting.
