2020 Suzuki Gsxs 750 Z AM0 0.7L Petrol · AF20 VYA

The latest MOT test result on 2026-05-27 indicates the Suzuki GSXS 750 AM0 passed without any recorded defects, marking a positive outcome following a series of previous failures and advisories. While the vehicle’s recent MOT history shows some recurring issues—particularly around exhaust noise, drive chain looseness, and front brake sponginess—these were either resolved or downgraded to advisories in the most recent tests, suggesting a trend toward stability rather than worsening mechanical degradation. The 2025-03-14 failure highlighted insecure rear brake master cylinder and low headlamp aim, both of which appear to have been addressed, as the 2024-03-20 MOT did not flag these again. However, the persistent advisory of a spongy front brake operation remains a concern that should be addressed promptly, as it may indicate underlying hydraulic or caliper issues, potentially leading to reduced braking efficiency or uneven wear if ignored. The vehicle’s recorded mileage of 8,853 miles over approximately six years represents a relatively low annual usage rate of around 1,476 miles per year, which is unusual for a motorcycle of this age and class. Typically, a GSXS 750 with six years of service would accumulate closer to 10,000–15,000 miles annually under normal riding conditions, especially given the sporty nature of the bike and the potential for higher stress on components like the drive chain, suspension, and brakes. The low mileage could reflect periods of inactivity, storage, or infrequent use, which may have contributed to certain wear patterns or issues such as standing corrosion, fluid degradation, or component stiffness. However, it also means that consumables like tyres, brake pads, and fluids may have been less frequently replaced, increasing the risk of age-related deterioration. For a prospective buyer, the most critical areas to inspect during a physical examination and test ride are the front brakes, drive chain, and exhaust system, given the recurring advisories. The spongy front brake operation suggests potential issues with brake fluid contamination, air in the system, or worn brake pads or pads themselves. During a test drive, listen for a consistent, firm pedal response without any pulsation or shuddering, and check for uneven tyre wear or brake disc warping. If the brake feel remains spongy, the master cylinder may need inspection or replacement, and the brake fluid should be flushed to remove moisture and contaminants. The drive chain’s slight looseness, though not severe, should be addressed promptly to prevent increased wear on the sprocket and chainrings, which could lead to premature failure. Visually inspect the chain for excessive stretch or elongation, and ensure it is properly lubricated and tensioned; a loose chain can also cause uneven power delivery and increased engine strain. Additionally, given the low annual mileage, the vehicle’s age, and potential periods of standing, the buyer should pay close attention to signs of standing corrosion, particularly on the frame, exhaust system, and brake components. Corrosion on the frame or exhaust can compromise structural integrity and emissions performance, while rust on brake discs or calipers may indicate binding or reduced braking efficiency. Check the tyre sidewall for signs of perishing or cracking, which can compromise their load-bearing capacity and safety, especially if the tyres have been stored for extended periods. The battery should also be tested for charge retention and physical condition, as low usage can lead to sulphation or internal failure. Finally, since the vehicle has not undergone a full fluid service in recent years, consider checking the condition of the engine oil, coolant, and brake fluid for signs of degradation or contamination. A thorough fluid analysis and a service schedule tailored to the bike’s age and usage profile would be prudent to ensure long-term reliability.
