2003 Honda CB900 0.9L Petrol · DF03 HKP

The 2003 Honda CB900 received its most recent MOT test on 2025-09-12, which was passed with three advisories: a minor exhaust gas leak, rear tyres worn close to the legal limit, and a slight fluctuation in front brake effort. While the vehicle has otherwise maintained a clean MOT history since 2022, the presence of recurring tyre wear issues and the brake fluctuation advisory suggests a pattern worth investigating further. The failed MOTs in 2017 and 2018, particularly the offside front shock absorber seal failures and missing rear reflector, indicate past mechanical wear that could have been mitigated with timely servicing. The fact that the 2020 MOTs included repeated very uneven tread advisories, despite passing in 2021 and 2022, implies either suboptimal tyre rotation practices or underlying suspension or alignment issues that may have persisted undetected. The vehicle’s recorded mileage of 31,886 miles over approximately 23 years represents an annual usage rate of around 1,386 miles, which is unusually low for a motorcycle of this age and model. Such low mileage often reflects periods of inactivity, storage, or infrequent use, which can lead to specific wear patterns and potential issues unrelated to driving. For example, prolonged standing can accelerate corrosion in brake systems, particularly on discs and calipers, as moisture and road salt can cause rusting or binding. Tyres that sit unused may develop sidewall perishing or dry rot, compromising their structural integrity and increasing the risk of sudden failure. Additionally, fluid degradation—such as in the hydraulic brake system or engine coolant—can accelerate over time, even without regular use, necessitating checks for contamination or separation. Given the low mileage and past MOT failures, the buyer should conduct a thorough physical inspection focusing on the following critical areas. First, examine the front and rear brake systems for signs of corrosion or binding, particularly on the discs, pads, and calipers. Listen for any grinding or squeaking noises when applying the brakes, which could indicate worn pads or warped discs. Check for uneven brake pad wear or excessive heat discolouration on the discs, which may signal underlying suspension or alignment issues contributing to the 2020 MOT advisories. Next, inspect the tyres for sidewall cracks, bulges, or tread depth uniformity, as the 2020 MOT records highlight persistent uneven wear. Rotate the tyres if necessary and ensure they are within legal limits, with a focus on the rear tyres, which were close to the limit in 2025. For fluids and mechanical components, verify the condition of the engine oil, transmission fluid, and brake fluid, as these can degrade over time regardless of usage. Check for leaks around the exhaust system, particularly the minor gas leak noted in 2025, and inspect the exhaust for rust or structural damage that could affect emissions or handling. The suspension, especially the offside front shock absorber, should be tested for firmness and fluid leaks during a test drive, paying attention to any clunking noises or excessive play, which may indicate further seal or component failure. Finally, given the vehicle’s age and low mileage, consider a comprehensive service history check, including timing belt replacement (if applicable), spark plug inspection, and battery health assessment. A 12V battery that has sat unused for years may be weak or failing, leading to poor starting or electrical system performance. If the vehicle has been stored in a damp environment, address any corrosion risks to the frame, exhaust, or electrical connections promptly.
