2009 Honda CBF 125 M-9 0.1L Petrol · LD09 VPG

A recurring pattern of drivetrain and braking system issues defines the mechanical history of this Honda CBF 125, despite a successful MOT pass on 30 May 2023. The record shows significant volatility in the condition of the drive chain and sprocket assembly, which has fluctuated between being recorded as excessively tight, excessively loose, or worn. This instability in the transmission components is compounded by past failures involving critical safety items such as a leaking fuel pipe and insufficient rear brake pedal travel. While the most recent test resulted in no recorded defects, the history of major failures regarding the drive chain and rear reflector in May 2023 indicates that the vehicle requires regular attention to maintain its roadworthiness. The recorded mileage of 3,912 miles over a 17-year lifespan represents an exceptionally low usage profile, averaging approximately 230 miles per year. Such minimal annual accumulation often suggests the vehicle has spent extended periods stationary rather than in regular service. Mechanically, this low-mileage usage can lead to specific issues where components like seals, fuel lines, and tyres may degrade due to age and lack of movement rather than wear. The presence of a fuel pipe leak in 2019 and the varying tension issues in the drive chain suggest that the components may be affected by the effects of long-term storage or infrequent operation. A prospective buyer should focus heavily on the drive chain and sprocket assembly during a physical inspection and test ride. Given the history of both excessive tightness and excessive looseness, it is essential to check for smooth power delivery and listen for any rhythmic slapping, clicking, or grinding noises coming from the drive side of the engine. A chain that is poorly maintained or has reached the end of its service life will often cause a noticeable jerkiness during throttle transitions or a heavy, vibrating sensation through the footpegs. The sprocket teeth should be inspected for a hooked or pointed profile, which would indicate the need for a full replacement of the kit. Attention must also be paid to the braking system and fuel delivery components following previous failures in these areas. During a test ride, the rear brake pedal should be checked for a firm, consistent feel with adequate travel, ensuring there is no excessive sponginess or sudden loss of pressure. The front brake discs, which were previously noted as scored and worn, should be inspected for deep grooves or uneven thickness that could cause pedal judder or reduced stopping power. Finally, a visual inspection of the fuel lines and connections is necessary to ensure there are no signs of weeping or degradation, particularly where the rubber meets the metal fittings.
