2020 WK Bikes Demon 125 0.1L Petrol · AU69 VBJ

The vehicle currently holds a roadworthy status, but the maintenance history indicates a trend of reactive rather than proactive care. While it passed its latest test in January 2025 at 9,179 miles, the failure in December 2024 revealed a significant period of neglect regarding essential components. The transition from a multi-point failure in late 2024 to a pass in early 2025 suggests faults were only addressed once they reached a legal failure threshold. The mileage profile is exceptionally low for a six-year-old motorcycle, averaging approximately 1,530 miles per year. There is a notable gap in usage between the March 2023 test at 2,213 miles and the December 2024 test where the bike covered nearly 7,000 miles in twenty months. Such intermittent use often leads to the degradation of rubber-based components, which is evidenced by the front and rear tyres falling below the 1.0mm legal limit during that period despite the low overall mileage. A buyer must physically inspect the steering assembly, as the steering headbearing was flagged as stiff or notchy in both the 2024 and 2025 tests. This recurring issue indicates a need for adjustment or replacement of the bearings. Furthermore, the drivetrain requires close scrutiny; the drive chain and sprockets were noted for wear and excessive slack in 2024, and the rear sprocket bearing showed detectable play. You should verify these items were fully rectified during the January 2025 pass to ensure mechanical integrity and safe operation.
