Should I check the MOT history before buying a 2020 Yamaha Yzf R125?

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 Yzf R125?

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 Yzf R125?

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 379 vehicles, the 2020 Yamaha Yzf R125 has a first-time MOT pass rate of 87%, 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 Yzf R125?

Moderate sample. 379 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2020 Yamaha YZF-R125 has a first-time MOT pass rate of 68.9%, which sits noticeably below the UK average of 80%, suggesting these bikes encounter more issues than typical vehicles at test time. With 10.5% of machines having experienced a dangerous defect, there's a meaningful reliability concern worth investigating on any individual example you're considering.

At around 10,600 miles average, these bikes are running relatively low mileage for their age, yet they're still averaging 0.39 failures and 1.5 advisories per test, indicating that even light use hasn't prevented issues from emerging. Before committing to one, get a full service history and have a trusted mechanic inspect the charging system and suspension, which commonly appear in advisory notices on this model.

The 2020 Yamaha Yzf R125 passes its MOT first time more often than most UK vehicles (87% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ 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.

For context

✅ Good baseline reliability. A 87% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 1.5 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 379 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.
