2006 Triumph Bonneville T 100 (865)
CarHunch analysed 256 real MOT records for the 2006 Triumph Bonneville T 100 (865). This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2006 Triumph Bonneville T 100 matches the UK average with an 80.6% first-time pass rate, suggesting broadly typical reliability for a 19-year-old motorcycle—though 14.1% of these bikes have recorded a dangerous defect at some point, which is worth investigating on any used example you view. At a median mileage of just 8,599 miles, these are lightly used machines, which bodes well for longevity if the one you're eyeing hasn't been thrashed.
Owners should expect around 1.15 failures and 3.7 advisories per test cycle, pointing to minor wear items and maintenance gaps rather than structural problems; this is typical of older air-cooled singles that need regular upkeep. Before handing over money, get a pre-purchase inspection that specifically covers the frame, electrics, and fuel system, since these bikes reward owners who stay ahead of small issues.
What to check before buying a 2006 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.
