1985 Kawasaki Z750 P4

CarHunch analysed 161 real MOT records for the 1985 Kawasaki Z750 P4. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1985 Kawasaki Z750-P4 is a genuinely rare survivor: only 3.9% pass first time, compared to the UK average of 80%, making it one of the hardest bikes to get through MOT on the first attempt. The good news is that dangerous defects are almost non-existent at 0.6%, so when failures do happen, they're typically minor fixability issues rather than safety-critical problems.

The median mileage of 24,854 miles is remarkably low for a 39-year-old machine, suggesting most surviving examples are cherished barn finds rather than daily riders, which explains both the test failures and the minimal advisory count of 0.2 per vehicle. If you're considering one, budget for a thorough pre-purchase inspection and expect to spend time sorting small issues—these bikes fail on detail rather than danger, but patience and mechanical knowledge are essential.

What to check before buying a 1985 Kawasaki Z750 P4

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.
