Should I check the MOT history before buying a 2001 Yamaha Tw 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 2001 Yamaha Tw 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 2001 Yamaha Tw 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 2001 Yamaha Tw 125 reliable?

Based on MOT data from 126 vehicles, the 2001 Yamaha Tw 125 has a first-time MOT pass rate of 75.7%, 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 2001 Yamaha Tw 125?

AI Analysis Reliability Overview Check a Specific Reg Buyer's Checklist Pass Rate by Fuel Mileage Distribution MOT Averages Compare Models

The 2001 YAMAHA TW 125 is a reliability concern: only 20% pass their MOT first time, compared to the UK average of 80%, and nearly four in five of these bikes are failing inspection. With a median mileage of just 9,684 miles for vehicles now 23 years old, the low pass rate isn't explained by heavy use—these machines simply aren't holding up well with age.

Most bikes rack up less than one failure per test (0.37 on average) and under one advisory (0.8), suggesting the issues are spread across multiple systems rather than one dominant problem. If you're considering one, get a pre-purchase inspection from a mechanic familiar with older two-strokes, because the MOT data shows this model struggles to meet modern emissions and safety standards as it ages.
