2001 Yamaha FZS600 0.6L Petrol · Y457 AWP

The 2001 Yamaha FZ600’s latest DVSA MOT test on 25th July 2026 resulted in a passing grade, though it did not entirely clear the vehicle of advisories. The presence of a recurring "exhaust noisy" advisory under category 8.1.1(a) indicates a persistent issue that has not been resolved, suggesting either a persistent mechanical fault in the exhaust system or a more fundamental problem with the engine’s emissions control components. The previous MOT on the same date recorded both this advisory and a passing headlamp aim test, which implies the headlamp alignment was corrected or was within acceptable limits at the time, but the exhaust concern remains unresolved. This pattern of repeated advisories without a definitive failure grade suggests either a lack of proper maintenance addressing the root cause or a vehicle that has been subject to intermittent or unresolved mechanical wear. For a buyer, this indicates a need for careful inspection of the exhaust system and emissions-related components, as well as a proactive approach to resolving the noise issue before it escalates into a more costly repair. The recorded mileage of 33,423 miles for a vehicle of this age—approximately 1,337 miles per year—is notably low for a 25-year-old motorcycle, particularly when compared to typical usage patterns for similar models. Such low mileage often reflects periods of extended storage or infrequent use, which can lead to specific wear patterns and potential issues related to standing conditions. For example, prolonged idling or stationary periods can cause brake disc corrosion, particularly on the inner surfaces where moisture and road debris accumulate, potentially leading to binding calipers or uneven brake pad wear. Additionally, the engine’s lubrication system may suffer from reduced fluid circulation when the motorcycle is not in use, risking increased wear on seals, bearings, and the engine’s internal components over time. Tyre wear can also be influenced by low usage, with sidewall perishing becoming more pronounced due to age rather than mileage, and potential dry rot developing in the rubber components if not properly maintained. The low annual mileage also raises concerns about fluid degradation, such as brake fluid absorption of moisture or engine oil thinning from lack of use, which could compromise performance when the motorcycle is eventually put into service. To conduct a thorough inspection of this Yamaha FZ600, the prospective buyer should prioritise several critical areas, particularly given the unresolved exhaust advisory and the vehicle’s age and low mileage profile. Begin with a visual and functional inspection of the exhaust system, focusing on the catalytic converter, mufflers, and exhaust pipes for signs of rust, cracks, or excessive wear that could contribute to the persistent noise. Listen for variations in exhaust tone during acceleration and deceleration—abnormal pulsations or a lack of smoothness may indicate a failing catalytic converter or exhaust manifold issue. Check for any oil leaks around the exhaust components, as these could signal damaged gaskets or seals contributing to emissions-related problems. Next, examine the brakes for signs of corrosion, particularly on the inner surfaces of the brake discs and the brake calipers, which may be binding if the motorcycle has been stationary for extended periods. Inspect the brake fluid reservoir for contamination or moisture buildup, and test the brake pedal for firmness and responsiveness, as soft or spongy pedal feel could indicate air in the system or fluid degradation. For fluid servicing, given the vehicle’s age and low usage, the buyer should consider replacing the engine oil and filter, as well as the brake fluid, at the earliest opportunity. Engine oil should be changed to a high-quality, full synthetic blend suitable for older two-stroke engines, with the filter replaced to prevent contaminants from accelerating wear. Brake fluid should be replaced to remove absorbed moisture, which can compromise braking performance and lead to corrosion in the brake system. Additionally, check the tyre condition thoroughly, paying close attention to the sidewalls for signs of perishing or cracking, which can compromise structural integrity and safety. Inspect the tyre tread depth for uniformity, as uneven wear may indicate suspension or alignment issues that warrant further investigation. Finally, verify the battery’s health, ensuring it holds a charge and has no signs of corrosion or swelling, as a failing battery in a low-mileage vehicle can lead to poor starting performance and potential electrical system failures. If the vehicle has been stored in a damp or extreme environment, it may also benefit from a thorough inspection of the fuel system for moisture ingress or varnish buildup, which can affect engine performance upon restart.
