2009 Yamaha WR 125 X 0.1L Petrol · LC09 VKB

The most recent MOT test on the 2009 Yamaha WR125X, conducted on 2026-05-15, resulted in a passing grade, though it was accompanied by several persistent advisories that indicate ongoing but manageable issues. The vehicle’s maintenance history shows a pattern of recurring defects, particularly in the braking system, suspension components, and electrical controls, with two previous failures in 2024 and 2025. While the latest test did not flag any major failures, the presence of binding front and rear brakes, along with the previous major issues—such as a defective throttle control and non-functional brake lamps—suggests that the vehicle has not been fully addressed in critical areas. The advisories on the exhaust noise and steering stiffness further imply that wear and potential long-term degradation are factors to monitor closely, especially given the vehicle’s age and the fact that it has not undergone a comprehensive service in several years. The recorded mileage of 31,792 miles for a 17-year-old WR125X is notably low, averaging around 1,870 miles annually—a rate that could reflect either light usage or extended periods of inactivity. Such low mileage is unusual for a motorcycle of this age, particularly one that appears to have accumulated wear-related issues across multiple MOT tests. While low mileage might suggest reduced exposure to wear from driving, it also raises concerns about standing corrosion, particularly in the brake systems, suspension components, and electrical wiring, which can degrade over time due to prolonged exposure to moisture and environmental factors. The absence of recent service records further complicates this, as fluid degradation and component stiffness from disuse are common in vehicles left unused for extended periods. As a prospective buyer, your immediate inspection should focus on the braking system, given the repeated advisories of binding front and rear brakes and the previous major failures related to brake functionality. Check for uneven brake pad wear, corrosion on brake discs or calipers, and any signs of binding or excessive pedal travel, which could indicate seized components or warped discs. During a test drive, listen for any grinding noises during braking, which may signal disc wear or caliper binding, and observe if the brakes respond uniformly across both axles. The suspension, particularly the rear shock absorber and ball joints, also warrant close inspection due to the previous failure of the bottom shock bush and worn rear suspension arm. Look for excessive play in the suspension, clunking noises when cornering, or uneven coil spring compression, which could signal bush wear or structural damage. Beyond mechanical checks, address the electrical issues highlighted in the MOT history, such as the bent clutch lever pivot and sticking indicator switch. Test all lights, including dipped beam and brake lamps, to ensure they function correctly, as the previous failure of the rear headlamp and front stop lamp underscores the importance of reliable lighting. The exhaust noise advisory suggests a potential leak or wear in the exhaust system, which should be inspected for leaks or excessive vibration, as these can lead to reduced performance or emissions issues. Finally, given the vehicle’s age and low mileage, pay particular attention to the condition of the tyres, checking for sidewall cracking or perishing, which can compromise structural integrity. Additionally, verify the health of the 12V battery, as prolonged disuse can lead to sulphation or corrosion in terminals, and ensure all fluids—including brake fluid, coolant, and chain lubricant—are within their serviceable life, as fluid degradation can accelerate wear in components like seals and bearings. If possible, obtain the service book or service history to confirm the last time fluids were changed and when major components were inspected.
