2002 KTM EXC400 0.4L Petrol · CK02 AJY

The vehicle's maintenance history shows an inconsistent pattern of mechanical upkeep, with the most recent test on 9 May 2025 indicating a failure due to a leaking fuel system component. Although it passed immediately following that failure at 19,999 miles, the recurring nature of fuel system issues, seen previously in the May 2017 failure, suggests potential vulnerability in the fuel delivery components. The maintenance trend appears unstable, as the vehicle frequently oscillates between clean passes and failures related to electrical components and fluid leaks. The mileage profile is exceptionally low for a 2002 model, averaging approximately 833 miles per year. A significant jump occurred between the October 2023 test at 13,130 miles and the May 2025 test at 19,999 miles, representing nearly 7,000 miles of use in roughly 19 months. This is a notable increase compared to the long periods of inactivity seen between 2017 and 2022. Such low overall mileage often implies the vehicle has spent significant time stationary, which can lead to rubber degradation and seal drying despite the low mechanical wear on the engine. A prospective buyer should prioritize a physical inspection of the fuel system and lines to ensure the May 2025 leak was fully rectified and not a symptom of wider degradation. The October 2023 test flagged play in the rear wheel bearing, and while the vehicle passed subsequent tests, the integrity of the wheel bearings and hubs should be verified. Given the history of electrical failures, including faulty headlamp switches and horn controls, a thorough check of the wiring loom and switchgear is necessary. The record also highlights repeated issues with lighting configurations and registration plate compliance. While these are often minor, the history of stop lamp malfunctions and incorrect positioning suggests that the electrical system or mounting hardware may be unreliable. Because this is an off-road use vehicle with no lights fitted, the tester's notes regarding missing indicators and mirrors are expected, but the mechanical integrity of the fuel system and wheel assembly remains the primary technical concern.
