Yamaha Ybr 125 (2015)
2015 Yamaha Ybr 125
CarHunch analysed 199 real MOT records for the 2015 Yamaha Ybr 125. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2015 Yamaha YBR 125 is a serious reliability concern, with just a 9.5% first-time pass rate compared to the 80% UK average—this 125cc commuter bike is failing MOT at a rate nine times worse than typical vehicles. Only 4.3% of petrol examples pass first time, and while dangerous defects are uncommon at 3%, the sheer frequency of failures suggests systemic maintenance issues.
These bikes are running low mileage for their age (median 10,860 miles), yet still accumulating an average of 0.18 failures and 0.2 advisories per test, pointing to neglect rather than wear. If you're considering one, budget for significant remedial work before it will pass MOT—check the service history meticulously and have an independent mechanic inspect it, as casual owners appear to be leaving these bikes in poor condition.
What to check before buying a 2015 Yamaha Ybr 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.
