The 2012 KTM 125's 78.9% pass rate sits just below the UK average of 80%, which is unremarkable, but the genuinely concerning figure is that 27.6% of these bikes have shown a dangerous defect at some point—well above typical thresholds and a serious red flag for any potential buyer. This reliability weakness is underscored by an average of 1.57 failures per vehicle, indicating persistent structural or mechanical issues that recur across the cohort.

At 9,573 miles average and 8,713 miles median for vehicles now 12+ years old, these KTMs have been ridden hard relative to their age, which partly explains the high failure rate but doesn't excuse it. With 5.7 advisories per bike on average, expect ongoing maintenance surprises; before buying one, have a trusted mechanic inspect the frame, suspension, and braking system thoroughly, since those are where the dangerous defects are clustering.

We have limited data for the 2012 KTM 125 — 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.

Drive chain worn but not considered excessive
Lighting 34.2%
Drive chain slightly loose · Rear reflector on motorcycle missing · Rear reflector missing · …
Usually cheap to fix. Worth confirming all lights work before collecting.
Brake wear 18.6%
Front Brake indicates slight fluctuation of brake effort · Front Roller brake test indicates slight fluctuation of brake effort · Front Stop lamp does not illuminate immediately a brake applies · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Suspension & steering 10.6%
Steering headbearing has slight free play · Nearside Front Shock absorber has a light misting of oil · Offside Front Shock absorber has a light misting of oil
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
