Our Verdict
A solid recommendation for a low-mileage
Given the very low mileage of 17,353 miles, your primary focus should be on how the bike has been stored. Low-mileage motorcycles can sometimes suffer from 'age-related' issues rather than wear-related ones, such as perished rubber components, seized cables, or degraded fuel. Check the condition of the tyres and any rubber hoses, as these may be aged regardless of tread depth.
When negotiating, ask for any evidence of routine maintenance, as the MOT record only confirms the vehicle met minimum roadworthiness standards. Specifically, inquire about the most recent brake service to ensure the 'slight fluctuation of brake effort' noted in the 2024 MOT has been fully rectified and is not a recurring issue with the master cylinder or calipers.
As an 865cc petrol motorcycle, running costs will be moderate. Fuel economy on these Bonneville models is generally respectable for a large-capacity twin, though actual figures will depend on riding style. Tax and insurance groups for a 2005 Triumph will vary significantly based on your personal profile and location.
Maintenance costs for this model typically involve periodic valve clearances and oil changes. Given the low mileage, you may find that consumables like tyres and brake pads last a long time, but expect to pay for specialist parts if any mechanical components require replacement.
Pay close attention to the braking system. The MOT history for this specific registration (T100PEB) shows 'slight fluctuation of brake effort' on the front brake in both 2022 and 2024. Ensure the lever feel is consistent and firm during your test ride; any sponginess or sudden changes in pressure should be investigated.
Additionally, inspect the electrical system and battery. Low-use motorcycles can develop electrical gremlins or battery issues if they haven't been kept on a trickle charger. Check the condition of the chain, sprockets, and drive belt (if applicable) to ensure they haven't developed surface rust from sitting idle.
This 2005 Triumph Bonneville T100 presents with exceptionally low mileage for its age, having covered only 17,353 miles in approximately 21 years. The MOT history shows a consistent pattern of passing, with the most recent two tests in 2025 and 2026 recording no defects at all. While there were minor advisories regarding front brake effort in 2022 and 2024, the vehicle's recent history suggests these issues were resolved.
No aggregate reliability data is available for the Triumph Bonneville T100 to provide a statistical comparison.
