Moderate sample. 416 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2006 Suzuki GZ 125 K6 is a genuine reliability concern, with a first-time MOT pass rate of just 64.5%—nearly 16 percentage points below the UK average of 80%—and a troubling 25.2% of examples having suffered dangerous defects at some point. This combination suggests structural or systemic issues that buyers should take seriously rather than overlooking as minor age-related wear.

With a median mileage of only 10,320 miles for an 18-year-old motorcycle, these machines have been lightly used, yet still average 1.94 failures and 5.8 advisories per test, pointing to corrosion, neglect, or design weaknesses rather than riding wear. Before committing to one of these bikes, get a specialist pre-purchase inspection focused on frame integrity, fuel system condition, and electrics—the low pass rate suggests these areas are where most problems hide.

The 2006 Suzuki Gz 125 K6 has a decent first-time pass rate (77.6%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 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 5.8 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 416 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.
