The 2019 Yamaha YZF R125 has a first-time MOT pass rate of 68.9%, which trails the UK average of 80% by a noticeable margin—this is a bike that demands more attention than most to keep compliant. The dangerous defect rate of 17.1% is within acceptable bounds, so while reliability isn't stellar, it's not a safety alarm.

With a median mileage of just 9,369 miles for a five-year-old machine, these are relatively lightly used learner bikes, yet they still average 0.64 failures and 2.4 advisories per test. Before buying, have a pre-purchase inspection focus on the electrical and exhaust systems, as these typically rack up the advisory count on small displacement sports bikes.

The 2019 Yamaha Yzf R125 passes its MOT first time at roughly the UK average rate (82.8%) — solid but worth checking this vehicle's history carefully.

⚠️ Around 1 in 8 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
🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.
🔧 Expect consumable spend. An average of 2.4 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 601 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.
