Triumph Bonneville 865 (2010)
2010 Triumph Bonneville 865
CarHunch analysed 194 real MOT records for the 2010 Triumph Bonneville 865. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2010 Triumph Bonneville 865 passes its MOT slightly more reliably than the UK average, with an 82.5% first-time pass rate versus 80% nationally, and a low dangerous defect rate of just 14.4% means serious safety issues are uncommon. The median mileage of 7,881 miles is remarkably low for a 14-year-old bike, suggesting many have been cherished rather than ridden hard, which bodes well for condition.
What concerns is the average of 2.9 advisories per test, indicating trim, minor corrosion, or wear items crop up regularly on these machines. Check the service history carefully and budget for routine maintenance, then get a pre-purchase inspection focused on the electrical system and fuel delivery—common weak points on air-cooled British twins of this era.
What to check before buying a 2010 Triumph Bonneville 865
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
