1999 Yamaha FZS600 0.6L Petrol · V971 DBV

A persistent issue with exhaust noise defines the recent testing history of this motorcycle, appearing as an advisory in three consecutive tests including the most recent pass on 2026-08-08. While the vehicle has maintained roadworthiness, the 2024 record shows a failure necessitated by a poorly positioned front brake lever and incorrect headlamp aim, alongside a minor defect with the rear position lamp. The recorded mileage of 37,564 miles is low for a vehicle of this age, averaging approximately 1,391 miles per year over 27 years. This usage pattern indicates the motorcycle has spent significant periods of time stationary or has been used sparingly. Mechanically, such low annual accumulation can lead to the degradation of rubber components and seals, which is reflected in the recorded oil misting from the front shock absorbers. Inspection should focus on the exhaust system to determine if the recurring noise advisory stems from a leak, internal baffle failure, or an aftermarket system that may be nearing its legal limit. During a test drive, listen for excessive rasping or popping and check for soot marks around the manifold and joints. The front fork legs require close examination for oil leaks; a light misting was flagged in 2024, and any increase in fluid loss will affect damping and braking stability. Ensure the front brake lever is correctly adjusted for the rider's reach, as this was a primary cause for failure in 2024. Feel for any stiffness or lack of smooth return in the lever action. Additionally, verify the intensity of the rear position lamp and the accuracy of the headlamp beam, as these lighting issues have previously required correction to meet DVSA standards.
