2021 KTM 125 Duke 21 0.1L Petrol · EX71 LOF

A recurring front‑brake fluctuation dominates the recent MOT narrative: an advisory for slight effort variation in October 2024 was followed by a failure for excessive fluctuation in September 2025, yet the September 2026 test recorded a clean pass with no defects noted. This progression suggests that the brake issue was either remedied or has temporarily cleared, but the prior failure indicates a component that has required attention and may warrant re‑inspection. The recorded 9,445 miles over roughly five years equates to just under 1,900 miles per annum, a mileage level that is low for a 2021 model. Such limited use can reduce wear on wear‑items such as tyres, chain, and brake pads, but it may also imply periods of inactivity where moisture can accumulate in brake components or corrosion can develop on exposed fittings. The absence of large mileage jumps between tests points to a consistent, light‑use pattern rather than a sudden surge in kilometres that would accelerate component fatigue. When evaluating the front‑brake system, feel for any pulsation or sponginess in the pedal during a short road‑test, particularly under moderate braking effort. Listen for uneven squeal or grinding that could indicate warped discs or uneven pad wear, and inspect the caliper pistons and brake lines for signs of leakage or corrosion. Verify that the brake fluid appears clear and at the correct level, and check the condition of the pads and discs for uneven thickness or scoring, as these are common origins of effort fluctuation. Beyond the brakes, confirm that the low‑mileage usage has not concealed wear on the chain, sprockets, and suspension bushings, which can deteriorate even with limited riding if the bike has been stored for extended periods. A thorough visual inspection for surface rust on the frame and sub‑frame, as well as a functional test of the steering head bearings for play, will help ensure that the overall structural integrity remains sound before committing to purchase.
