This 1999 Kawasaki ZX600-G2 is a serious reliability concern: just 28.2% pass first time against the UK average of 80%, meaning roughly seven in ten fail their MOT on the first attempt. Only 3.9% have ever recorded a dangerous defect, so catastrophic safety issues are uncommon, but the sheer failure rate suggests systematic problems with maintenance or wear across the model.

The median mileage of 19,895 miles is remarkably low for a 25-year-old bike, indicating most survivors in this cohort are lightly used—yet they still fail at alarming rates, which points to age-related decay rather than abuse. With 0.38 failures and 1.1 advisories per vehicle on average, expect corrosion, electrical gremlins, and exhaust work to be routine; before buying one, have an independent technician inspect the frame, wiring, and fuel system thoroughly.

The 1999 Kawasaki Zx600 G2 passes its MOT first time at roughly the UK average rate (83.6%) — solid but worth checking this vehicle's history carefully.
