2009 Yamaha WR 125 R 0.1L Petrol · PJ59 LEU

A recurring theme in the MOT record is the repeated advisory about a slightly loose near‑side drive chain, first noted in 2012 and again in 2016, suggesting that chain tension has been an ongoing maintenance point; the most recent test in March 2026 introduced a new advisory concerning a short off‑side front brake lever, yet the bike still satisfied the pass criteria, indicating no outright failures have been recorded. With only 6,725 miles logged over seventeen years the average annual mileage works out to roughly 400 miles, well below typical usage for a 125 cc motorcycle. The gap between the 2018 and 2026 MOT entries also implies a period when the bike was either off the road or not subjected to annual testing, meaning many components have aged more by time than by distance. Low mileage reduces wear on the engine, transmission and clutch, but rubber seals, hoses and tyre compounds can deteriorate simply with age, and the chain’s condition may be more a function of elapsed time than of miles ridden. Prospective buyers should give the drive chain immediate attention. Verify that the chain sits snugly on the sprockets with the correct slack as specified by Yamaha, and inspect both the chain links and the front/rear sprockets for signs of wear, elongation or hooked teeth. During a short ride listen for a rattling or clicking noise, feel for any jerky power delivery, and watch for uneven chain movement that could indicate worn adjusters or mis‑aligned sprockets. If the chain shows excessive stretch or the sprockets are worn, replacement of the chain and both sprockets, together with a fresh lubrication, would be prudent. The short front brake lever noted in the latest MOT warrants a focused brake check. Confirm that the lever reaches the handlebar with a firm, progressive feel and that the front brake engages without excessive travel or sponginess. Examine the brake pads for remaining thickness and even wear, and inspect the hydraulic lines and master cylinder for any signs of fluid leakage or corrosion. A brief stop‑test at low speed should reveal any pull or loss of braking efficiency; if the lever feel is abnormal, a hydraulic bleed or a more thorough brake system service should be arranged before committing to purchase.
