Triumph Thunderbird Storm (2011)
2011 Triumph Thunderbird Storm
CarHunch analysed 104 real MOT records for the 2011 Triumph Thunderbird Storm. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2011 Thunderbird Storm passes its MOT first time 87% of the time—a solid 7 percentage points above the UK average—and dangerous defects crop up in only 14% of vehicles, so safety isn't a major concern for the model. The bike does rack up nearly five advisory items per test on average, suggesting minor wear and electrical niggles are common as these machines age.
With a median mileage of just under 12,000 miles, these Thunderbirds are running low for their age, which explains the strong pass rate and relatively modest 0.89 failures per vehicle. If you're buying one, check the service history carefully and have a pre-purchase inspection focus on the electrical gremlins and gaskets that typically show up as advisories—a well-maintained example should be dependable.
What to check before buying a 2011 Triumph Thunderbird Storm
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.
