2003 Honda FJS 600 0.6L Petrol · HF03 KFJ

The vehicle remains roadworthy, though the maintenance trend has shifted from a perfect record to showing mechanical concern. After three years of clean passes between 2021 and 2024, the most recent test on October 14 2025 at 34,103 miles identified an engine oil leak. This indicates the onset of seal degradation that requires attention, as it was not present in previous inspections. The mileage profile is exceptionally low for a 23-year-old motorcycle, averaging approximately 1,483 miles per year. The data shows significant periods of inactivity between August 2021 and September 2022, where the vehicle covered only 29 miles in over thirteen months. Since the 2022 test, usage has increased slightly, covering 5,339 miles over three years to reach the current 34,103 mark. This low-frequency usage often leads to age-related hardening of rubber components and fluid breakdown rather than traditional mechanical wear from high mileage. A buyer must prioritise a physical inspection of the oil leak to determine if it is a minor gasket seep or a more significant seal failure. Given the low mileage and long intervals between use, the inspector should specifically check for perished brake lines, seized caliper pistons, and dry rot in the fork seals. The structural integrity of the frame and swingarm should be verified for corrosion, as low mileage does not prevent surface rust on older vehicles that have sat for extended periods.
