Should I check the MOT history before buying a 2018 Sinnis Zs 125 79 Hoodlum?

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 2018 Sinnis Zs 125 79 Hoodlum?

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 2018 Sinnis Zs 125 79 Hoodlum?

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.

Based on MOT data from 294 vehicles, the 2018 Sinnis Zs 125 79 Hoodlum has a first-time MOT pass rate of 74.3%, 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 2018 Sinnis Zs 125 79 Hoodlum?

This 2018 Sinnis ZS 125-79 Hoodlum is significantly less reliable than the UK average, with a first-time MOT pass rate of just 54.3% against the national benchmark of 80%. Roughly one in seven of these bikes have recorded a dangerous defect during their MOT history, which is a material safety concern for prospective buyers.

The median mileage of just over 5,000 miles suggests these are lightly used commuter bikes, yet they're still failing MOT at a high rate—indicating quality or maintenance issues rather than wear-related problems. With an average of 0.78 failures and 3.1 advisories per vehicle, expect to budget for regular remedial work; a thorough pre-purchase inspection by a specialist mechanic is essential before committing to one.

We have limited data for the 2018 Sinnis Zs 125 79 Hoodlum — treat the figures below as indicative rather than definitive.
