Should I check the MOT history before buying a 2020 Yamaha Ys 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 2020 Yamaha Ys 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 2020 Yamaha Ys 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 2020 Yamaha Ys 125 reliable?

Based on MOT data from 412 vehicles, the 2020 Yamaha Ys 125 has a first-time MOT pass rate of 83.5%, 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 2020 Yamaha Ys 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.

Moderate sample. 412 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2020 Yamaha YS 125 falls short of the UK average, with a 70.3% first-time pass rate compared to 80% nationally—a meaningful gap that suggests this model has more than its fair share of teething troubles. The 18% dangerous defect rate sits just below the concerning threshold, so check the full inspection history carefully when viewing an example.

At nearly 8,800 miles on average, these bikes are carrying typical mileage for their age, but the 0.52 average failures and 1.6 advisories per vehicle point to small recurring issues rather than major mechanical failures. If you're considering one, factor in a pre-purchase inspection from a qualified motorcycle technician—the middling MOT record means don't rely on the pass certificate alone.

The 2020 Yamaha Ys 125 passes its MOT first time at roughly the UK average rate (83.5%) — solid but worth checking this vehicle's history carefully.

⚠️ Around 1 in 8 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.

For context

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 1.6 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 412 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
