1999 Derbi Senda (restricted)

CarHunch analysed 169 real MOT records for the 1999 Derbi Senda (restricted). This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 1999 Derbi Senda has a catastrophic first-time MOT pass rate of just 6%, compared to the UK average of 80%—this is a severe reliability red flag for any prospective buyer. Fortunately, dangerous defects are rare at 1.8%, but the near-total failure rate means nearly every vehicle will need significant work before it passes inspection.

These bikes have typically covered only 13,840 miles, so mileage isn't the issue; the problem is age and mechanical deterioration over two decades. With barely any failures or advisories being logged per vehicle, the data suggests these machines are so worn out they're often being abandoned rather than repeatedly repaired, so buying one requires accepting you're restoring a vintage bike, not acquiring a functional runabout.

What to check before buying a 1999 Derbi Senda (restricted)

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.
