2021 WK Bikes SX 125 0.1L Petrol · AX21 UHV

The vehicle currently holds a roadworthy status following a pass on August 22, 2025, but the maintenance trend shows a reactive rather than proactive approach. While the bike passed the most recent test at 16,042 miles, it failed just ten days prior at 15,983 miles due to critical mechanical defects. The transition from a major failure involving wheel bearings and brake assemblies to a pass indicates that significant repairs were only addressed after they reached a point of legal failure. At 16,042 miles over five years, the motorcycle has covered a low average of approximately 3,200 miles per year. This low usage suggests light road exposure, which can sometimes correlate with issues affecting rubber components and seals if the vehicle sits stationary. The data shows 713 miles driven between the August 2024 and August 2025 tests, confirming consistent low mileage patterns, yet the rapid deterioration of wheel bearings and shock absorbers suggests these components may be suffering from agerelated degradation despite the low total mileage. A buyer must conduct a thorough physical inspection of the drivetrain and braking systems to ensure the repairs made in August 2025 were executed correctly. The record notes a recurring noisy exhaust and internal baffle damage dating back to 2024, which persisted into the 2025 records. Furthermore, the nearside front shock absorber remains flagged with light oil misting as of the latest test, indicating a seal is beginning to fail. This should be monitored for signs of active leaking that could lead to total failure. The wheel bearings require close scrutiny for any remaining play or noise, as they were flagged for potential seizure and overheating in the August 2025 failure. Given the history of a missing brake pad retaining pin and fluctuating brake effort, the entire braking circuit should be checked for secure mounting and even wear. The persistent nature of the exhaust issues suggests that the silencer or front pipe is nearing the end of its functional life and may require replacement to prevent further emissions or noise failures.
