2025 Kawasaki Z900RS: the modern classic that still hits the sweet spot
Kawasaki’s Z900RS has long been the benchmark for “retro done right.” For 2025, it returns with the same winning formula: classic 1970s Z1 style wrapped around a smooth, tractable 948cc inline‑four and everyday‑friendly ergonomics.

How it rides
The Z900RS is all about refinement and feel. The engine’s midrange is the star—clean fueling and a generous spread of torque make it easy to flow through traffic or carve backroads without constant shifting. The chassis is stable yet playful, the fork and shock offer useful adjustability, and the assist & slipper clutch keeps downshifts drama‑free. Traction control and ABS work quietly in the background, preserving the analog vibe without sacrificing safety.

Buying tips
- Check your market for SE or Café‑style variants; trims and colors vary.

- Plan a test ride focused on midrange throttle response and ergonomics—two of the Z900RS’s biggest strengths.
