2011 Yamaha WR125R 0.1L Petrol · WR60 TYA

A persistent electrical defect at the rear of the machine defines the DVSA record for this 2011 Yamaha WR125R. Two separate stop lamp failures were recorded across the 2020 and 2022 test cycles, one a present failure for the lamp not illuminating and the other classified as dangerous because the lamp remained on with the brakes released. The intervening and subsequent tests up to the most recent pass on 7 August 2023 are clean, but the duplication of the same component group across two different presentations is a notable indicator of an underlying loom, switch, or earth fault that may have been addressed by repair rather than replacement. Beyond the lighting concerns, the rest of the record is relatively sparse on advisories, with the only other flagged items being tyre wear close to the legal limit and a slightly loose drive chain noted in 2019. Against an age of approximately fifteen years, the recorded mileage of 9,753 miles equates to an annual accumulation of roughly 650 miles, which is substantially below typical commuter or leisure use for a learner-legal trail bike. The test history contains multi-year gaps between presentations, consistent with periods of storage or seasonal use rather than continuous riding. From a mechanical standpoint, low annual mileage of this nature tends to expose the machine to moisture ingress in unused cavities, drying and cracking of rubber components such as fork seals and tyre sidewalls, and surface corrosion on the chain, sprockets, exhaust mounting, and ferrous parts that benefit from regular motion to displace condensation. The fact that an advisory for drive chain and sprocket wear was already raised in 2019, despite limited mileage, supports the likelihood of standing-related deterioration rather than wear from use. For a prospective buyer, particular attention should be paid to the rear lighting circuit at first power-up, including confirmation that both stop lamps extinguish cleanly when the brake lever is released and that the front stop lamp operates correctly given it has previously failed on test. Inspect the front and rear brake levers for any binding or excessive free play, as a sticking switch mechanism was the most recent dangerous defect. Examine the drive chain for tight spots by rotating the rear wheel backwards through a full revolution, check sprocket teeth for the hooked or sharpened profile that the 2019 advisory hinted at, and measure remaining tyre tread depth across the centre and edges, particularly on the rear which was already at 2.5mm at the 2020 test. During the test ride, listen for any clonks or knocking from the front end over small bumps, which can indicate dried suspension bushes or stiction in the forks following long storage, and feel for any weave or instability that may point to aged tyre rubber despite apparently legal tread. Confirm that the engine warms evenly without excessive smoke from a cold start, as prolonged standing periods can affect piston ring seating and cause oil seepage past valve guides. Finally, inspect the underside and swingarm area for surface oxidation, examine the exhaust mounting rubbers for perishing, and ensure all electrical earth points are clean and secure given the recurring stop lamp history.
