# 1998 KAWASAKI ZX 900-C1

This 1998 Kawasaki ZX 900-C1 is a serious reliability concern, with only a 21.5% first-time MOT pass rate—less than a quarter of the UK average of 80%. Fewer than 1% of these bikes have ever recorded a dangerous defect, which is reassuring on safety grounds, but the dramatically low pass rate points to chronic issues with general condition and maintenance.

At a median mileage of 23,757, these machines are well-used 26-year-old bikes, and the data suggests many owners aren't keeping up with basic upkeep. The average bike generates 0.16 failures and 0.4 advisories per test—modest numbers individually, but combined with the high failure rate they signal that these bikes tend to accumulate multiple small problems rather than one catastrophic fault. If you're considering one, budget for a full pre-purchase inspection by a Kawasaki-savvy mechanic and be prepared for repair costs; this is a machine for enthusiasts with mechanical confidence, not casual riders.

The 1998 Kawasaki Zx 900 C1 passes its MOT first time more often than most UK vehicles (87.1% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
