1988 Honda CBR400 0.4L Petrol · E133 CGK

The most recent MOT on 2025-03-27 recorded a pass but noted a front brake fluctuation (1.2.1 (e)), a defect that also appeared in the 2023-11-25 MOT. However, the same date also shows a fail for a non-functional horn (7.7 (a)) and the same brake issue. This suggests unresolved or recurring brake system concerns, possibly linked to hydraulic pressure, pad wear, or master cylinder faults. The horn failure is a minor but notable safety risk, as it affects signaling capability. A 2023-11-18 MOT revealed brake binding (1.2.1 (f)), a missing rear reflector (4.8.2 (a) (ii)), and a damaged rear valve stem (5.2.3 (j)). These issues were partially addressed by 2023-11-25, when the rear valve stem was repaired, but the brake binding and reflector issues reappeared in the 2025 MOT. The recurring brake problems and reflector damage indicate potential neglect or systemic wear in the braking and lighting systems. The vehicle’s mileage of 22,445 miles (38 years old) equates to roughly 591 miles per year , a very low usage rate. This could imply long periods of inactivity, which may accelerate wear on components like seals, gaskets, and electrical systems. However, low mileage also suggests less mechanical stress on moving parts like the engine and transmission.
