2020 WK Bikes Demon 125 0.1L Petrol · DU20 GPJ

The vehicle’s most recent MOT test on 18 March 2023 at just 666 miles confirmed full roadworthiness with no defects recorded. This represents a stable maintenance trend, though the test’s age—over three years since the last inspection—means critical components like brakes, suspension, and emissions systems may now require verification. The absence of advisories or failings in the single available record suggests no recurring mechanical issues were previously identified, but the prolonged period since testing introduces uncertainty over wear on high-wear items. The recorded mileage of 666 miles over six years equates to an exceptionally low annual average of approximately 111 miles, far below typical usage patterns for this class of vehicle. Such minimal usage could indicate prolonged storage, which may have accelerated deterioration of fluids, battery health, or rubber seals. Conversely, it might reflect careful preservation, though the lack of intermediate MOTs or service records means no verification of maintenance intervals exists. The vehicle’s current age and mileage combination demands particular scrutiny of items susceptible to stagnation, such as fuel system integrity and electrical reliability. Given the sparse MOT history, a buyer should prioritise an inspection of the battery and charging system, given the risk of sulphation from prolonged inactivity. Tyres, though not flagged in the single test, should be examined for uneven wear or age-related degradation, as the low mileage may mask underlying issues. The brakes—never tested for binding or excessive wear—require confirmation of disc thickness, pad condition, and hydraulic function. Suspension components, including bushes and coil springs, should be visually inspected for corrosion or play, especially if the vehicle has spent extended periods stationary. Emissions compliance, last verified in 2023, may also warrant attention if the bike has been stored in an environment prone to fuel degradation.
