2009 Yamaha WR125R 0.1L Petrol · PO59 KXV

The most recent MOT test conducted on 7 April 2026 resulted in a pass with no defects recorded. Reviewing the recent history, the vehicle underwent a failure in late August 2025 due to a major defect involving an excessively binding rear brake and insufficient braking efficiency during the roller brake test. However, the subsequent pass in August 2025 with no defects suggests that the braking system was professionally addressed and the identified mechanical fault was rectified. The overall maintenance trend appears to be stable and responsive, as the owner acted promptly to resolve the safety issues identified during the previous inspection. The recorded mileage of 7,855 miles is remarkably low for a 17-year-old machine, representing an average annual usage of approximately 462 miles. While this indicates minimal wear on the engine internals, piston rings, and gearbox, such low usage often implies the vehicle has been stored for extended periods. For a motorcycle, long-term standing can lead to specific mechanical issues that are not always evident during a brief MOT inspection, such as the degradation of rubber components, fluid contamination, or the seizing of moving parts due to a lack of regular lubrication and movement. A prospective buyer should perform a rigorous physical inspection focusing on age-related degradation rather than just wear. Closely examine the tyres for signs of perishing or sidewall cracking, as even with deep tread, old rubber loses its grip and structural integrity. Inspect the drive chain for surface corrosion or seized links, and check the brake discs for pitting or uneven wear patterns. Given the previous history of a binding rear brake, pay particular attention to the rear caliper for any signs of weeping fluid or sticking pistons, and ensure the braking action is smooth and progressive during a test ride without any shudder or loss of feel. Furthermore, verify that maintenance has been performed on a time-based schedule rather than solely on a mileage basis. Check the age of the brake fluid, as it is hygroscopic and will absorb moisture over time, potentially leading to internal corrosion and reduced performance. Inspect the fork seals for any signs of oil weeping and check the fuel system for any evidence of stale fuel or sediment. It is essential to confirm that the service history reflects regular oil changes and fluid replacements, as calendar-based degradation is a significant factor for vehicles that spend much of their lives stationary.
