Z400
The Z400 is the naked twin to the Ninja 400, sharing the same 399cc engine and 364-lb chassis in a more upright street fighter stance — discontinued in the US after 2023, but used supply at $3,500–$4,800 makes it the lowest-cost path to proven beginner-friendly parallel-twin performance. An honest beginner-to-intermediate bike that most riders will eventually outgrow, but not quickly.
