1997 Yamaha Trx850

CarHunch analysed 373 real MOT records for the 1997 Yamaha Trx850. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1997 Yamaha TRX850 passes its MOT at 84.8%, comfortably above the UK average of 80%, which suggests these bikes have held up reasonably well over the decades. Only 12.3% have ever recorded a dangerous defect, so safety issues are not a widespread concern for the model.

At nearly 27,400 miles on average, these machines show typical mileage for a motorcycle of this age, and the 5.2 advisories per vehicle indicate gradual wear rather than structural problems. If you're considering one, get a pre-purchase inspection focused on the routine failures that typically appear—an average of 1.55 per bike—and you'll have a clear sense of what work lies ahead.

What to check before buying a 1997 Yamaha Trx850

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.
