Our Verdict
A strong prospect for a Buell enthusiast
Prioritise a check of the exhaust system, as it has been flagged as noisy in both the 2024 and 2025 MOT tests. This may indicate a leak or a non-standard system that could eventually lead to a failure if it exceeds legal noise limits.
Given the extremely low mileage for a 22-year-old machine, request detailed service records. It is important to confirm if the bike has been stored for long periods, as this can affect seals and fuel system components.
The 984cc petrol engine will have higher fuel requirements than smaller capacity bikes. Insurance costs for this model are typically moderate, and road tax is based on the engine size.
Annual maintenance costs should remain manageable, though parts for older Buells can sometimes be harder to source. Estimated annual running costs are likely between £600 and £900, depending on usage.
Inspect the exhaust system thoroughly for holes, cracks, or loose mounts, as the MOT history specifically lists "Exhaust noisy" in September 2024 and September 2025.
Check all rubber components, including tyres and hoses, for signs of age-related cracking. With only 8,827 miles on the clock since 2004, the vehicle may have spent significant time stationary, which can lead to the perishing of rubber elements.
This green 2004 Buell XB9SX has recorded only 8,827 miles over its lifetime. The MOT history from 2022 to 2025 shows a consistent pass rate, although the two most recent tests highlight a noisy exhaust.
Aggregate reliability data is unavailable for the XB9SX, but this specific vehicle has a consistent MOT pass record.
