2004 Triumph Rocket 111
CarHunch analysed 221 real MOT records for the 2004 Triumph Rocket 111. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2004 Triumph Rocket 111 has a first-time pass rate of 77.5%, which trails the UK average of 80% by a modest margin—not a red flag, but worth noting as a slightly higher-than-average failure risk. With 15.8% of vehicles ever recording a dangerous defect, this bike sits in an acceptable range and shouldn't deter buyers on safety grounds alone.
These bikes are running relatively low mileage for their age, with a median of just 13,944 miles, suggesting many are weekend or collector machines rather than daily commuters. The average of 1.24 failures and 4.4 advisories per test indicates routine wear items (likely exhaust, cables, and brake components) are the main maintenance concern—budget for regular attention to consumables and inspect any example closely for rust and corrosion before you buy.
What to check before buying a 2004 Triumph Rocket 111
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.
