2017 Sinnis Zs 125 79 Hoodlum

CarHunch analysed 126 real MOT records for the 2017 Sinnis Zs 125 79 Hoodlum. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2017 Sinnis ZS 125-79 Hoodlum has a first-time MOT pass rate of 70.8%, sitting nearly 10 percentage points below the UK average of 80%, which suggests reliability concerns worth taking seriously. While the dangerous defect rate of 19.1% isn't alarming, it's close to the threshold where buyers should flag it as a potential issue.

These scooters are running relatively low mileage for their age—a median of just 5,277 miles—yet still averaging 0.85 failures per vehicle, indicating that age and sitting time may matter more than hard use. With 4.1 average advisories per test, electrical and wear items are clearly recurring niggles; before purchasing, get a pre-sale inspection focused on the charging system and battery health, as these bikes have spent time stationary.

What to check before buying a 2017 Sinnis Zs 125 79 Hoodlum

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.
