Triumph Rocket Iii (2011)
2011 Triumph Rocket Iii
CarHunch analysed 116 real MOT records for the 2011 Triumph Rocket Iii. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2011 Triumph Rocket III is a genuinely reliable motorcycle, with a 92.5% first-time MOT pass rate that beats the UK average by over 12 percentage points. Dangerous defects have appeared in just 13.8% of the cohort—well below the concern threshold—so safety-critical failures are not a systemic issue here.
These bikes are running low mileage for their age (median 13,103 miles), which suggests they're cherished rather than thrashed, though the 0.84 failures per vehicle indicates minor wear items do need attention. Budget for around three advisories per MOT cycle, but if you're buying one, a pre-purchase inspection by a Triumph-specialist mechanic will quickly flag whether you're getting a looked-after example or one that's been neglected.
What to check before buying a 2011 Triumph Rocket Iii
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.
