2009 Triumph Bonneville 0.9L Petrol · X28 BJF

The overall roadworthiness status of this Triumph Bonneville is exceptionally high, supported by a maintenance trend that remains entirely stable and clean. In the most recent test conducted on February 10, 2025, at 16,095 miles, the motorcycle passed with zero defects or advisories recorded. This flawless result follows identical clear passes on February 2, 2024, at 15,913 miles and February 20, 2023, at 15,527 miles. The absence of historical faults indicates that previous keepers maintained the machine to a high standard, avoiding the accumulation of neglected maintenance items. The mileage pattern reflects extremely light use over the life of the machine, averaging roughly 947 miles per year for its seventeen-year age. The data shows consistent, low-increment annual progression rather than long periods of being laid up off the road, evidenced by the steady addition of roughly four hundred miles between each successive winter test. This gentle usage profile means the engine and drivetrain have experienced minimal mechanical stress, though low annual mileage naturally shifts the primary risk from high-wear friction to age-related degradation. A physical inspection should focus on components vulnerable to time rather than heavy friction, specifically rubber fuel lines, fork seals, and tyre manufacture dates. Even though the braking system and suspension components generated no advisories during the recent test, a prospective buyer must examine the brake discs for pitting and check the fork stanchions for pitting or weeping oil caused by stagnant periods on a side stand. The chain and sprocket set, exhaust headers, and electrical connections also warrant close scrutiny to confirm that lack of use has not induced corrosion or stale fuel varnishing within the induction system.
