2010 Yamaha WR125 0.1L Petrol · LT10 OFV

The defining mechanical thread across the recorded MOT history is one of consistent roadworthiness punctuated by a cluster of light, recurring advisories concentrated around the drivetrain and braking components. The most recent test on 2024-03-16 returned a Pass with only two minor observations, which mirrors the general trajectory of the bike: it has never failed an MOT, and the advisories issued have remained in the advisory category rather than escalating into failure items. That said, the persistence of certain flags across multiple consecutive tests is notable. The missing chain guard and slightly loose drive chain appeared in both the 2024 and 2023 examinations, suggesting these items were either not addressed between tests or have recurred, and the 2023 test also picked up a noisy exhaust and a front tyre worn close to the legal limit. The 2022 pass carried an advisory for rear brake pads approaching minimum thickness, indicating that pad wear was being monitored a couple of years ago. The trend overall is stable rather than worsening, but the buyer should not interpret this as a clean bill of mechanical health, since advisories often represent components approaching the threshold of replacement. At 30,791 miles over approximately sixteen years, the WR125 has averaged around 1,924 miles per year, which is a notably modest annual accumulation for a motorcycle of this age and type. This level of use is consistent with a machine that has seen lighter recreational or short-commute duty rather than sustained daily riding, and there are no unusual spikes or gaps in the recorded mileage that would suggest clock irregularities or extended periods off the road between tests. Mechanically, lower annual mileage on a single-cylinder four-stroke like this tends to mean slower wear on consumables such as brake components and tyres, but it can also bring its own considerations: prolonged standing periods can lead to dried-out chain lubricant, surface corrosion on the drive chain and sprockets, and stale fuel issues that fall outside the MOT scope. The mileage figure itself appears plausible and consistent across the three recorded tests. Given the recurring chain-related advisories, the most immediate point of inspection on a test ride should be the drive chain and sprockets. With the chain guard noted as missing in two successive tests, it is worth checking the exposed chain runs for stiffness, tight spots, and adequate slack at the midpoint of the lower run, and confirming the sprocket teeth are not hooked or sharpened into a wave profile. A slightly loose chain at MOT threshold suggests adjustment slack has been creeping up, so any further travel on a road test, particularly under acceleration, indicates the chain and sprockets may now warrant a full replacement rather than mere adjustment. The rear brake pad advisory from 2022 is also worth verifying visually by inspecting pad material thickness through the caliper and checking the rear disc for a defined, unworn lip, since pads close to minimum two years ago will very likely have been replaced in the interim or may now be due again. Front-end and running gear checks should focus on the items flagged in 2023, particularly the front tyre and exhaust. The front tyre was close to the legal limit at the last recorded test, so on a current inspection look for tread depth across the central tread band and check for any cracking, flat-spotting from age, or uneven wear that might point to suspension or alignment issues. Stand on the pegs and apply the front brake to confirm there is no judder or pull, and bounce the front end to verify the forks feel consistent rather than rough or notchy over small bumps, which can indicate worn fork oil or seal issues. The exhaust noise advisory, described as noisy at the 2023 test, should prompt a stationary blip of the engine to listen for any rattling from the exhaust canister or joints, as a degrading silencer can also point to internal corrosion from low-mileage use. Finally, verify the chain guard is presently fitted, and confirm the rear brake still has firm, progressive feel without binding, since the pad advisory from 2022 makes this area worth a deliberate check before purchase.
