2017 Triumph Bonneville 0.9L Petrol · HN17 HDK

The Triumph Bonneville presents a clean bill of health on paper. The most recent MOT, conducted on 20 February 2026 at 4,056 miles, passed with zero defects, advisories, or warnings. Looking back through the full five-year record, every single test returned a pass with no faults whatsoever. This is a remarkably consistent maintenance trend. There is no evidence of recurring mechanical failures, structural corrosion, or deteriorating components. The record suggests a motorcycle that has been kept in sound operating condition with no outstanding defects at any point in its recent history. The mileage profile tells a clear story of extremely low usage. Across nine years of ownership, the odometer has advanced just 4,056 miles, averaging roughly 451 miles per year. The annual increments are remarkably steady: 118 miles between March 2022 and March 2023, 30 miles between March 2023 and March 2024, 47 miles between March 2024 and February 2025, and 118 miles between February 2025 and February 2026. There are no sudden spikes suggesting a period of heavy use, nor any suspiciously large gaps between tests that might indicate the bike was off the road untested. The MOT intervals themselves are annual and regular, which is consistent with a responsible owner maintaining the machine properly despite minimal riding. A clean MOT record and low mileage are encouraging, but they do not eliminate the need for a physical inspection. Motorcycles that stand for extended periods can develop issues that MOT tests do not always catch. Stale fuel, perished rubber hoses, degraded fork seals, and corroded brake lines are common on low-mileage machines that spend more time parked than riding. The tyres, despite having legal tread, may be aged and hardened from years of sitting, compromising grip. Battery condition and charging system health should also be verified, as infrequent use is the quickest way to kill a battery. A prospective buyer should inspect the underside and frame for any signs of corrosion, check that the brake calipers are not seized from disuse, and confirm that all electrics function correctly before committing to a purchase.
