This 1999 Kawasaki KMX125 falls short of the UK average, with a first-time pass rate of 75.4% against the national 80%, and a concerning 24.2% of vehicles in this cohort having suffered dangerous defects—a significant red flag for a prospective buyer. The combination of frequent failures (2.16 per vehicle on average) and an even higher advisory count (6.4 per vehicle) suggests these bikes need close maintenance attention to stay roadworthy.

Despite the modest median mileage of just 12,625 miles—quite low for a bike now 25 years old—these machines are clearly showing their age and use. Before purchase, get a pre-sale inspection from a qualified mechanic and budget for repairs to the areas most commonly flagged: expect work on brakes, suspension, and fuel system components to be common on any example you consider.
