Kawasaki Er 250 B2 (1986)
1986 Kawasaki Er 250 B2
CarHunch analysed 165 real MOT records for the 1986 Kawasaki Er 250 B2. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 1986 Kawasaki ER 250-B2 has a first-time pass rate of just 4.4%, catastrophically below the UK average of 80%, making it an exceptionally unreliable choice by modern standards. The good news is that no vehicles in this cohort have ever recorded a dangerous defect, so safety failures aren't the primary concern—instead, these bikes are simply worn out and difficult to get roadworthy.
With a median mileage of 26,901 miles for a bike now 38 years old, these machines are well-used survivors, and the minimal average failures (0.06 per vehicle) and advisories (0.1) suggest that when they do pass, they're in reasonable mechanical shape. If you're considering one, treat it as a project bike requiring serious recommissioning work rather than a ready-to-ride purchase, and budget for a specialist pre-purchase inspection before committing.
What to check before buying a 1986 Kawasaki Er 250 B2
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.
