The 2021 Z900RS is a homage to the 1973 Z1 900, with a teardrop tank, round mirrors and an oval LED taillight over a retuned Z900 inline-four. The engine is tuned for stronger low and mid-range torque, and the chassis and ergonomics give a relaxed, upright ride. Traction control, ABS, LED lighting and a digital instrument panel are standard.
