The 2008 Suzuki GZ 125 K8 passes its MOT just 62% of the time on first attempt, well below the UK average of 80%, and that's a genuine concern—one in four of these bikes have recorded a dangerous defect at some point, which flags serious safety issues. This 125cc commuter bike is averaging 10,691 miles across its lifespan, which is reasonable for the age, but owners are racking up an average of 1.73 failures per test and 5.0 advisories, suggesting the model ages poorly and requires consistent maintenance.

If you're considering one, budget for regular repair work and check the service history carefully—these bikes aren't especially cheap to keep on the road, and the high dangerous defect rate means you'll want a pre-purchase inspection from someone who knows the model well.

We have limited data for the 2008 Suzuki Gz 125 K8 — treat the figures below as indicative rather than definitive.

⚠️ 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.
