1978 Suzuki GS750 0.7L Petrol · EEL 834T

The latest DVSA MOT test for the Suzuki GS750 was conducted on 2024-07-10, resulting in a passing outcome with a single advisory noted under 1.2.1(f) regarding rear brake binding, which is described as not excessively severe. This follows a consistent pattern of passing MOTs from 2018 to 2024, with only one failure recorded in 2018 for front headlamp alignment—an issue unrelated to the vehicle’s structural or mechanical roadworthiness. The absence of repeated failures or critical defects over the past six years suggests a stable maintenance history, though the advisory on rear brake binding warrants closer attention to ensure it does not progress to a more serious condition, particularly if the vehicle is subjected to frequent heavy braking. The recorded mileage of 1,474 miles for a vehicle aged approximately 48 years represents an exceptionally low annual usage rate of around 31 miles per year, which is highly unusual for a motorcycle of this vintage. Such low mileage often reflects periods of prolonged inactivity, particularly if the vehicle has been stored for extended durations, leading to potential issues such as corrosion, fluid degradation, and wear from static conditions. For example, standing for long periods can cause brake discs to corrode or bind, as seen in the advisory, while suspension components may stiffen or seize due to lack of movement. Additionally, fluids like brake fluid, coolant, and engine oil can degrade over time without regular servicing, compromising performance and safety. As a prospective buyer, the Suzuki GS750’s low mileage and age necessitate a thorough physical inspection to address potential long-term wear and standing-related issues. Begin with a visual and hands-on examination of the brake system, focusing on the rear brakes, where the advisory indicates binding or corrosion. Look for signs of rust on brake discs, caliper seals, or the brake line connections, and listen for any unusual grinding or dragging noises when braking, especially under acceleration or when the vehicle is stationary. The suspension should be checked for stiffness or excessive play in the coil springs, control arms, and suspension bushes, which may have dried out or deteriorated from disuse. Inspect the exhaust system for leaks, corrosion, or structural weakness, and ensure the catalytic converter is intact, as emissions-related failures are common in older motorcycles left unused for extended periods. Prioritise the inspection of the electrical system, including the 12V battery, as low-mileage vehicles often suffer from battery failure due to prolonged disuse. Test the battery’s charge capacity by attempting to start the engine or running lights, and check for corrosion on terminals. Fluid levels should be verified, with particular attention to brake fluid, which can absorb moisture and become gelled over time, compromising hydraulic pressure. The fuel system should also be inspected for signs of contamination or sediment buildup, as standing fuel can degrade. Finally, examine the tyre condition for sidewall cracking or perishing, which is a common issue in older vehicles exposed to weather elements, and ensure the tread depth meets legal requirements. If the vehicle has been stored in a damp or poorly ventilated environment, consider a thorough internal inspection for mould, rust, or other forms of deterioration. Schedule a professional service if the advisory on rear brake binding persists, particularly if the vehicle is intended for regular use, to prevent potential failure during critical braking scenarios.
