2004 Honda CBR 1000 RR-4 1.0L Petrol · RY04 AAK

Persistent issues with the steering headbearing define the mechanical record of this motorcycle, appearing as a recurring advisory across multiple tests including the most recent pass on 18 June 2024. While the vehicle has passed its latest inspection, the chronic nature of the notchy steering headbearing combined with previous flags for pitted front brake discs and a worn drive chain suggests a pattern of gradual wear on critical control and drivetrain components. An average annual accumulation of approximately 1,431 miles over 22 years indicates a low-usage profile for a machine of this age. Such a low mileage rate often suggests the vehicle has spent significant periods stationary, which can contribute to the pitting observed on the brake discs and the stiffness noted in the steering headbearing. During a physical inspection and test ride, specific attention must be paid to the steering action. A notchy or stiff feeling when turning the handlebars from lock to lock while stationary, or a tendency for the bike to track unevenly, would confirm the ongoing headbearing issue flagged in 2022 and 2024. The front brake discs should be examined for surface pitting and scoring, and the rear brake fluid level should be verified against the reservoir markings to address the most recent advisory. The drive chain and exhaust system also require scrutiny based on previous records. Listen for excessive noise or irregularities in the exhaust note, and inspect the drive chain for uneven wear, kinking, or excessive slack. Any judder during braking or a lack of smoothness in the steering will indicate that the previously noted advisories remain unresolved.
