Should I check the MOT history before buying a 1990 Honda Cb450?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 1990 Honda CB450 matches the UK average first-time MOT pass rate of exactly 80%, so reliability is right in line with what you'd expect from a 34-year-old bike. Dangerous defects show up in about 1 in 8 examples, which isn't alarming but worth factoring into a pre-purchase inspection.

Most surviving examples sit around 30,000 miles — quite low for a bike this age — suggesting these are either well-maintained machines or riders who don't clock serious mileage. With an average of 1.5 failures and 5.4 advisories per test, plan on routine work to keep one roadworthy; scrutinise the most recent MOT history carefully before buying, as that tells you whether problems are escalating or stable.

We have limited data for the 1990 Honda Cb450 — treat the figures below as indicative rather than definitive.
