2020 Kawasaki BX 125 ALF 0.1L Petrol · EX70 GCV

The Kawasaki BX 125 Alf presents a generally stable roadworthiness profile, though the January 2026 test cycle reveals a brief but notable dip in maintenance attention. The most recent test on 9 January 2026 at 45,848 miles returned a clean pass with zero defects, indicating that any issues flagged days earlier had been rectified. However, the failed test on 6 January 2026 at 45,836 miles is concerning in its specificity. The tester flagged a central rear brake that was excessively binding, a central rear stop lamp remaining illuminated when the brakes were released, and all direction indicators failing to operate correctly. These are not gradual wear items. A binding caliper and a stuck brake lamp switch suggest a component fault or seizure rather than routine deterioration, and the simultaneous failure of every indicator points to a single electrical fault, likely a failed relay, a wiring break, or a switch issue, rather than five individual bulb failures. The fact that all three defect categories were resolved within three days before the pass suggests a targeted repair, but the buyer should verify that the underlying cause was properly diagnosed rather than masked by a simple reset or temporary fix. The mileage accumulation is consistent and unremarkable for a 2020 machine. The recorded readings show 27,354 miles in August 2023, 28,338 miles in January 2024, 35,939 miles in January 2025, and 45,848 miles in January 2026. That final jump of nearly 10,000 miles in twelve months is the steepest annual increase in the record, up from a prior average closer to 7,000 to 7,500 miles per year. The step from 28,338 to 35,939 between January 2024 and January 2025 already signals increased usage, and the 2025 to 2026 interval confirms the trend. This is not inherently problematic, but it does mean drivetrain and braking components have seen heavier loading in the period immediately preceding the binding brake fault. A buyer inspecting this machine in person should focus on the rear braking system and the electrical circuit that was flagged. Check the rear caliper for free movement of the pistons and slides, and spin the rear wheel with the brake released to confirm there is no residual drag. Inspect the rear brake lamp switch, typically mounted near the rear brake pedal or master cylinder, for correct adjustment and full return. Test every direction indicator and confirm the telltale on the dashboard flashes at a consistent rate, as a rapid or irregular flash can still indicate a partial wiring fault even if all lamps illuminate. Beyond the flagged items, examine the front brake pads and discs, suspension linkage play, and swingarm pivot bearings, as the higher recent mileage increases the likelihood of wear in these areas. The MOT record is otherwise clean, but the January 2026 failure is a reminder that even a recently passed test can follow a fault that warrants closer scrutiny.
