1997 Honda CBR 400 RR 0.4L Petrol · R225 DKX

The 1997 Honda CBR 400RR has maintained a clean MOT history across three consecutive tests, all passing without defects at the most recent inspection on 10 April 2026. This suggests the vehicle has been kept in a mechanically sound condition, with no recurring issues or advisories to indicate worsening wear. The most recent test, just three months ago, confirms no binding brakes, excessive corrosion, or suspension faults—critical areas for a high-performance bike of this age. However, the lack of advisories or minor defects in any test does not preclude hidden wear; a thorough mechanical inspection remains essential. The recorded mileage of 40,007 miles at the latest test reflects an exceptionally low annual average of around 1,380 miles over nearly 29 years. This suggests either minimal use or prolonged periods of storage, which could accelerate deterioration of components like rubber seals, cables, and battery health. The most notable gap between tests is between July 2024 and April 2026—a nine-month interval with only 577 miles accumulated. While this period is within the standard 12-month MOT validity, it raises questions about whether the bike was actively ridden or simply stored, potentially leading to neglected maintenance such as chain lubrication, throttle body cleaning, or fuel system stagnation. Given the bike’s age and the absence of MOT defects, a buyer should prioritise inspecting the chain and sprocket for excessive wear or stretch, as low-mileage bikes often suffer from rust or seized components when stored. The suspension linkages, including fork seals and rear shock mounts, should be checked for dryness or leaks, as prolonged inactivity can degrade rubber bushes and coil springs. Tyre tread depth, while not flagged in MOTs, warrants verification—especially if the bike has been stationary for extended periods, as sidewall cracking or embedded debris could indicate neglect. Finally, the battery and electrical connections should be tested, as older bikes frequently develop parasitic drain or corroded terminals when not regularly used.
