Sinnis Hoodlum 125 (2021)
2021 Sinnis Hoodlum 125
CarHunch analysed 262 real MOT records for the 2021 Sinnis Hoodlum 125. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Sinnis Hoodlum 125 has a first-time MOT pass rate of just 50.8%, significantly below the UK average of 80%, which means roughly half of these bikes fail their test and require remedial work. Dangerous defects affect less than one in ten vehicles (8.8%), so while the pass rate is poor, catastrophic safety issues are not widespread.
These machines average only 3,393 miles at the median, suggesting light use despite being three years old—so failures are less about wear and more about build quality or maintenance gaps. With 1.1 advisories per vehicle and 0.28 failures on average, the typical issue is minor rather than major, but the high failure rate means you should budget for remedial work and have any purchase inspected by a mechanic familiar with Chinese-built scooters before committing.
What to check before buying a 2021 Sinnis Hoodlum 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.
