Yamaha Sr 125 (2001)
2001 Yamaha Sr 125
CarHunch analysed 139 real MOT records for the 2001 Yamaha Sr 125. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2001 Yamaha SR 125 is a genuinely poor performer on its first MOT attempt, with just 32.8% passing versus the UK average of 80%—this is a major red flag that suggests either systematic maintenance neglect across the fleet or underlying design issues. The dangerous defect rate of 2.2% is mercifully low, but the sheer failure rate means you're looking at a bike that will almost certainly need work before it passes test.
These machines are racking up modest mileage for their age (median 15,160 miles), yet still accumulating 0.4 failures and 0.9 advisories per vehicle on average, which points to age-related deterioration rather than hard use. If you're considering one, budget heavily for pre-purchase inspection and assume it will need brake, lighting, or suspension work to get through its first MOT—don't buy on faith that it's "fine."
What to check before buying a 2001 Yamaha Sr 125
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
