1991 Kawasaki Zx1100 C1

CarHunch analysed 130 real MOT records for the 1991 Kawasaki Zx1100 C1. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1991 Kawasaki ZX1100-C1 is a genuine reliability outlier—just 7.8% of these bikes pass their MOT first time, compared to the UK average of 80%, making it one of the poorest performers on test. Dangerous defects are thankfully rare at 0.8%, so safety isn't the primary concern; instead, it's chronic wear and degradation typical of 30+ year-old machines that have clocked an average of 33,041 miles.

With a median mileage of 37,330 miles for a bike now in its fourth decade, these are generally low-use classics rather than everyday riders—yet they still fail on an average of 0.07 defects per test, suggesting that age and storage issues matter far more than miles. If you're considering one, budget for a full pre-purchase inspection by a Kawasaki specialist and assume immediate remedial work; this isn't a buy-and-ride proposition, but rather a restoration or deep-pocket hobby project.

What to check before buying a 1991 Kawasaki Zx1100 C1

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.
