Sinnis Hero (2019)
2019 Sinnis Hero
CarHunch analysed 122 real MOT records for the 2019 Sinnis Hero. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2019 Sinnis Hero has a first-time MOT pass rate of just 51.2%, well below the UK average of 80%, which is a significant red flag for reliability. With 16.4% of vehicles showing dangerous defects, this Chinese-market bike presents genuine safety concerns that deserve serious investigation before purchase.
At just 5,351 miles median mileage for a five-year-old bike, these are very lightly used machines, yet they're still failing MOTs at nearly double the normal rate—suggesting design or build quality issues rather than wear-and-tear problems. Before buying one, have a trusted independent mechanic inspect it thoroughly, and check the specific failure patterns on the MOT history to understand whether the problems are fixable or systemic.
What to check before buying a 2019 Sinnis Hero
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.
