2020 Bullit Hero 125

CarHunch analysed 172 real MOT records for the 2020 Bullit Hero 125. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2020 Bullit Hero 125 has a first-time MOT pass rate of just 62.3%, well below the UK average of 80%, which suggests these bikes struggle with test readiness or have underlying durability issues. The good news is that dangerous defects are relatively uncommon at 9.3%, so safety isn't the primary concern.

With a median mileage of 2,966 miles for a four-year-old bike, these machines are lightly used, yet they're still accumulating an average of 0.46 failures and 1.6 advisories per test—a sign that minor maintenance lapses compound quickly. Before buying one, have a pre-purchase inspection focus on electrics, exhaust systems, and brake components, as these are the areas most likely to trigger MOT issues on budget commuter bikes.

What to check before buying a 2020 Bullit Hero 125

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.
