2001 Yamaha XJ900 0.9L Petrol · Y96 RDD

A pattern of recent clean testing follows a period of mechanical instability in late 2022, suggesting a trend of improving roadworthiness. While the vehicle passed its most recent inspection on 15 March 2026 with no defects recorded, the history shows a significant failure in December 2022 involving a major defect with a binding rear brake and a non-functioning front position lamp. This was followed by a minor advisory in January 2023 regarding an exhaust gas leak, though the subsequent two years of testing have returned no recorded issues, indicating that these specific components have likely been addressed. The recorded mileage of 83,889 miles over a 25-year lifespan represents a relatively low annual accumulation of approximately 3,356 miles. Such a low average suggests the vehicle has not been subjected to high-frequency, long-distance usage, which can often lead to accelerated wear on drivetrain components and engine internals. However, for a vehicle of this age with this specific mileage profile, the mechanical focus shifts from high-mileage wear to the potential effects of infrequent use, such as the degradation of rubber seals, gaskets, and various fluid properties that can occur when a machine sits stationary for extended periods. Prospective buyers should pay close attention to the braking system and the exhaust assembly during a physical inspection and test ride. Given the 2022 failure for a binding rear brake, it is essential to check for any signs of heat discoloration on the rear disc or an unusual smell of burning material after a short ride. During the test, listen for any uneven deceleration or a dragging sensation when releasing the brake lever or pedal. The exhaust leak noted in 2023 should be verified by listening for any rhythmic ticking or rasping sounds emanating from the manifold or header pipes, particularly during cold starts or under load, which could indicate a failing gasket or loose mounting hardware. Electrical integrity should also be a priority, specifically regarding the lighting circuits that failed in 2022. Ensure all position lamps, indicators, and brake lights function correctly without flickering. Because the vehicle has operated at low annual mileages, a thorough visual inspection of all external rubber components, such as fork seals and fuel lines, is advisable to check for perishing or cracking that is common in low-use, older vehicles. Any irregularities in the engine's idle or sudden changes in exhaust note during the test ride should be treated as a prompt to inspect the exhaust system and intake seals more closely.
