The 2012 Yamaha YZF R125 has a serious reliability problem: just 31.2% pass their MOT first time, nearly half the UK average of 80%. With 13.4% of these bikes having suffered a dangerous defect at some point, this is a genuine safety concern for potential buyers.

These are relatively low-mileage machines (median 12,913 miles for their age), yet they're accumulating an average of 0.76 failures and 3.3 advisories per test, suggesting poor build quality or inadequate maintenance rather than wear and tear. Before buying one, have a pre-purchase inspection by a Yamaha specialist and budget for immediate repairs—the average owner should expect to fix problems before the bike is roadworthy.

The 2012 Yamaha Yzf R125 passes its MOT first time at roughly the UK average rate (77.3%) — 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 3.3 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 584 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.
