2013 Triumph Bonneville T 100 (865)

CarHunch analysed 114 real MOT records for the 2013 Triumph Bonneville T 100 (865). This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2013 Triumph Bonneville T 100 passes its MOT at 82.6%, slightly ahead of the UK average of 80%, and only 7% of tested bikes have ever recorded a dangerous defect—a reassuringly low figure that suggests this model is fundamentally sound. The petrol-only variant (all 113 vehicles) performs consistently at 82.4%, so there's no variance to worry about between fuel types.

At just over 9,500 miles on average for an 11-year-old machine, these Bonnevilles are genuinely low-mileage examples, which explains why they're averaging only 0.54 failures per test—owners either ride them sparingly or maintain them well. With 1.8 advisories per vehicle typically involving wear items rather than structural issues, the practical takeaway is straightforward: grab a pre-purchase inspection by someone who knows British bikes, check service history carefully, and budget for routine consumables, but don't expect chronic problems.

What to check before buying a 2013 Triumph Bonneville T 100 (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.
