What the Z400 is
The Z400 takes the Ninja 400's 399cc twin and puts it in an upright naked package. Peak power is typically quoted lower than the faired Ninja in some markets due to mapping/exhaust differences, but the chassis DNA is shared. It suits commuting and canyon riding more than track-focused posture.
