Should I check the MOT history before buying a 2021 Sinnis Hoodlum 125?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2021 Sinnis Hoodlum 125?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2021 Sinnis Hoodlum 125?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2021 Sinnis Hoodlum 125 reliable?

Based on MOT data from 262 vehicles, the 2021 Sinnis Hoodlum 125 has a first-time MOT pass rate of 82.2%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2021 Sinnis Hoodlum 125?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

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.

We have limited data for the 2021 Sinnis Hoodlum 125 — treat the figures below as indicative rather than definitive.

⚠️ About 1 in 12 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
