Should I check the MOT history before buying a 1999 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 1999 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 1999 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 1999 Yamaha Tw 125 reliable?

Based on MOT data from 117 vehicles, the 1999 Yamaha Tw 125 has a first-time MOT pass rate of 84.6%, 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 1999 Yamaha Tw 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 1999 YAMAHA TW 125 is a significant reliability concern, with only 16.1% passing MOT first time against the UK average of 80% — this is a genuinely poor result that signals systemic issues across the tested cohort. The good news is that dangerous defects are rare at 2.6%, so safety-critical failures aren't the main problem here.

These bikes are turning up with very modest mileage (median 16,334 miles), yet still failing MOT at high rates, which suggests neglect or age-related deterioration rather than wear from use. Average failures sit at just 0.2 per vehicle but advisories climb to 0.7, pointing to corrosion, worn consumables, and minor electrical gremlins typical of 25-year-old motorcycles — before you buy one, get an independent inspection to assess brake condition, fuel system integrity, and wiring harness rot.
