Honda Cbr400 (1990)
1990 Honda Cbr400
CarHunch analysed 211 real MOT records for the 1990 Honda Cbr400. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1990 Honda CBR400 hits exactly the UK average with a 79.6% first-time pass rate, signalling typical reliability for a bike of this age. However, 15.6% of these machines have experienced dangerous defects at some point, which is a meaningful concern for a nearly 35-year-old machine—worth a thorough pre-purchase inspection.
The median mileage of 37,363 suggests these bikes have been ridden hard rather than left in sheds, which actually bodes well for mechanical sympathy and maintenance history. Expect around 1.4 failures and 4 advisories per MOT test, pointing to wear items like brakes, lights, and suspension rather than catastrophic engine problems—budget for routine maintenance but don't expect major rebuild costs if the bike's been looked after.
What to check before buying a 1990 Honda Cbr400
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.
