2022 Honda CBF 125 M-M 0.1L Petrol · CF22 OLO

A pattern of progressive rear-drive chain deterioration defines the mechanical history of the 2022 Honda CBF 125 M-M, with the chain transitioning from "excessively loose" at the December 2026 MOT to "worn" at the January 2026 follow-up, while the wheel alignment remained marginally misaligned throughout both assessments. Both the prior failed MOT in February 2026 and the subsequent successful pass in February 2026 share the same core chain-related advisories, indicating that the drivetrain component is experiencing continuous wear rather than isolated incidents. This trajectory suggests the chain has not recovered between tests and continues to require attention, with the alignment issue persisting as a separate but related concern. The odometer reads 3,459 miles on a chassis originally manufactured in 2022, which translates to approximately 865 miles per year—a figure far below typical daily commuting distances and strongly implies extended periods of inactivity or very light use. The narrow gap of just eight months between the November and January 2026 MOTs further supports that the vehicle has not been driven regularly since the October 2025 test, meaning the low mileage does not yet reflect cumulative component wear. While low mileage might suggest minimal engine hours, the documented chain wear across two consecutive MOTs demonstrates that even moderate annual usage rapidly degrades drivetrain components, so the current mileage figure alone provides limited insight into the engine's true health. The rear drive chain sprocket has progressed from "excessively loose" to a clearly worn state between the two most recent MOTs, a change that typically produces a noticeable skipping or clicking sensation when the gearbox shifts under acceleration, particularly on mild inclines where chain tension is most vulnerable. The rear-nail puncture in the right rear tyre, noted in the January 2026 MOT alongside the chain advisory, indicates direct impact damage that should be examined for sidewall deformation, embedded fragments, or compromised bead seating that could compromise handling and braking performance. Additionally, the persistent wheel alignment misalignment—measured slightly off at both the September 2025 and January 2026 tests—can cause the vehicle to pull to one side under load and may manifest as uneven tyre wear or difficulty maintaining straight-line cruising speed. During a test drive, pay close attention to whether the chain makes audible skip or grind sounds when moving through each gear, especially during deceleration or uphill sections where the chain is under maximum tension. Inspect both rear tyres for the nail entry point and check for any embedded debris or bulging sidewalls that could signal underlying structural damage. Verify that the steering returns completely to centre without binding and perform a slow-speed turn to confirm the nose tracks straightly; any pulling to one side would indicate the alignment issue remains unresolved. If either the chain exhibits visible wear, the nail damage is confirmed, or the alignment feels off, these are serious concerns that should not be overlooked before committing to purchase.
