2020 Mutt Fat Sabbath 125
CarHunch analysed 162 real MOT records for the 2020 Mutt Fat Sabbath 125. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2020 MUTT FAT SABBATH 125 is a concerning buy from a reliability standpoint: only 58.1% pass first time, well below the UK average of 80%, and 8.6% have recorded dangerous defects. This suggests either quality issues with the model or that owners aren't maintaining them properly, making it a risky choice for someone wanting hassle-free motoring.
These bikes are still relatively low-mileage at an average of 4,552 miles, so the poor pass rate isn't down to age-related wear—it points to inherent problems. With 0.39 failures and 0.9 advisories per vehicle on average, expect to budget for repairs, and before purchasing one, get a pre-buy inspection from a mechanic familiar with this model to identify what's actually failing.
What to check before buying a 2020 Mutt Fat Sabbath 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.
