The Z1 had full instrumentation and an electric start, produced 82 bhp and had a maximum speed of 130 mph to 132 mph (210 km/h).

Where the 250 was the perfect starter bike, the 650 established itself as arguably Kawasaki's most reliable bike ever made. Ninja 650 owners have reported great things about their purchase, including a 4.3 out of 5 in reliability.

This reputation for Kawasaki motorcycle reliability comes from decades of reliable performance, it isn't uncommon to see used Kawasaki Ninjas that are years, if not decades, old. They have a ton of miles and are still running just as strong as the day they rolled off the production line.
