2006 Yamaha XT 660 R 0.7L Petrol · YN06 FSA

The most recent MOT on 13 February 2024 was passed with no recorded defects, indicating that the bike is currently compliant with the statutory safety standards. Earlier in the record there were several failures and a number of advisories, particularly around lighting, throttle operation and the front shock, but the last two years have shown a clear shift to clean passes, suggesting that the owner has addressed the major issues and that the maintenance trend is now stabilising rather than deteriorating. With a recorded 33,411 miles on a 2006 model the average annual distance works out at roughly 1,670 miles per year, which is considerably below the typical usage for a motorcycle of this age. Such low mileage often points to light riding or extended periods of storage, both of which can be benign for wear‑related components but can also allow age‑related degradation of rubber, seals and metal to progress unnoticed. The mileage figure therefore does not guarantee low wear; rather it highlights the need to focus on calendar‑based deterioration rather than purely distance‑based wear. The recurring advisories merit close inspection. The front shock absorber was noted with a light misting of oil in 2021 – a sign that the internal seals may be beginning to leak, which can lead to reduced damping, a soft or clunking feel on uneven road, and premature shock failure; a visual check for oil on the fork legs and a bounce test are advisable. The bike has repeatedly been without indicator lights fitted, and several lighting failures were recorded in 2018 and 2021; verify that all position, stop and turn signals operate correctly and that the headlamp aim is within legal limits, as mis‑aimed lights can cause glare and safety concerns. Tyre sidewall cracking was flagged in 2019 and rear tyre wear close to the legal limit in 2017, so examine both tyres for dry‑rot, cracks, and tread depth, remembering that ageing tyres can fail even with low mileage. The brake hoses were noted in sleeves on multiple occasions – inspect the hose condition for cracking, swelling or loss of flexibility, and test the brakes for any sponginess or uneven pull that could indicate hose or caliper wear. The exhaust was described as noisy in 2018, which may point to a cracked pipe or loose mounting; listen for rattles and check for rust or holes that could affect emissions and rider comfort. Finally, the throttle sticking fault recorded in 2018 should be confirmed by a smooth, linear throttle response on the test ride, with no hesitation or sudden jumps that could indicate carburetor or throttle cable wear. Given the bike’s age and low mileage, a thorough age‑related inspection is essential. Examine the tyre sidewalls for perishing, as rubber can become brittle after years on the shelf, and replace any tyre that shows cracking regardless of tread depth. Check the 12 V battery for voltage under load and inspect for corrosion on terminals, as long periods of inactivity can weaken the charge. Look over the frame, swingarm and forks for any surface rust, especially in the rear sub‑frame where standing water can accumulate; rust can progress to structural weakness if left unchecked. The XT660R is air‑cooled, but the engine oil should be fresh and free of sludge – a change of oil and filter is a low‑cost preventative step. Inspect the chain for correct tension, wear and proper lubrication, and verify that the sprockets are not excessively worn. Finally, a short ride should reveal any abnormal noises from the suspension, uneven braking, throttle lag or vibration that would indicate hidden wear. Addressing these points will give a prospective buyer a clear picture of the motorcycle’s current roadworthiness and the maintenance required to keep it reliable.
