1991 Triumph Trophy

CarHunch analysed 166 real MOT records for the 1991 Triumph Trophy. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 1991 Triumph Trophy passes MOT at 84.9%, which is comfortably above the UK average of 80%, suggesting these bikes are reasonably well-maintained overall. However, 12.7% have recorded dangerous defects at some point, which is moderate but worth checking in a pre-purchase inspection.

The median mileage of 34,486 miles is low for a 33-year-old bike, indicating most survivors are either garage queens or have genuine low use—either way, a positive sign for mechanical condition. With 1.2 average failures per vehicle, these Triumphs don't rack up major problems, though the 3.8 advisories per vehicle flag routine wear items like lights, exhaust, and cables; have any prospective purchase independently inspected for corrosion and fuel system integrity before committing.

What to check before buying a 1991 Triumph Trophy

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.
