1998 Triumph Speed Triple 0.9L Petrol · S848 AJO

A recurring issue with exhaust noise and significant gaps in the testing record define the roadworthiness history of this motorcycle. While the test on 29 March 2024 resulted in a pass, it was accompanied by an advisory for a noisy rear exhaust, a defect previously noted in 2012. The history shows a pattern of intermittent testing, with the vehicle passing most evaluations but failing on basic components such as lighting, registration plates, and tyre tread depth in earlier years. The recorded mileage of 8,258 miles is exceptionally low for a vehicle of this age, averaging approximately 295 miles per year. This usage profile, combined with the multi-year gaps in MOT records between 2013 and 2018 and again between 2018 and 2024, indicates the motorcycle has spent extended periods stationary. Such prolonged inactivity typically impacts the condition of rubber components and can lead to the accumulation of deposits within the fuel and braking systems. Attention should be directed toward the exhaust system, as the noise advisory has reappeared after a long interval, which may indicate internal corrosion or a failing baffle. During a test drive, listen for excessive drone or erratic idling that could suggest an exhaust leak. The 2013 failure regarding an insecurely mounted rear brake cylinder necessitates a close inspection of the rear braking assembly to ensure the mounting brackets are secure and there is no movement in the cylinder during lever application. Given the previous failure for tyre tread depth and the advisory for a loose drive chain, the current state of all consumables must be verified. Check for any uneven wear on the tyres and inspect the drive chain for kinking or seized links, which often occur during long periods of standing. Feel for any unusual vibrations or hesitation in power delivery during acceleration, which could be linked to the low-usage history and the aforementioned chain and exhaust issues.
