Utilizing the same basic DOHC 649cc parallel-twin engine from the company’s longtime middleweight Ninja 650 which was first introduced in 2006, the Z650 first made an appearance in the 2017 model lineup as part of Kawasaki’s new “Z” series of naked bikes. Bringing a slightly less sporty and more practical, “everyday” profile than the Ninja, the Z650 ditched the full bodywork and clip-on bars for sleeker, “sugomi-inspired” styling and a conventional handlebar for a slightly more comfortable riding position. A new trellis-style high-tensile steel tubular frame similar to the vaunted H2 series along with a new swingarm dropped a bunch of weight from previous-gen Ninja 650, and subtle changes to the parallel-twin powerplant improved its midrange-strong character.
Suspension components lack any adjustability other than spring preload in the rear shock to keep costs down, but the spring and damping rates were well chosen as demonstrated by the Z650′s ability to carve canyon roads and handle imperfect urban pavement with equal aplomb with a variety of riders aboard. Dual 300mm discs clamped by twin-piston slider calipers up front combined with a 220mm disc and single-piston slider caliper out back provide more than adequate stopping power for any situation, with an ABS model (for an additional $500 onto the sticker price) offering an added safety net.
More updates came in 2020 with slightly more aggressive sugomi styling, a TFT panel replacing the old hard-to-read LCD unit, LED headlights, Bluetooth connectivity to the dash via Kawasaki’s Rideology app, and a slightly larger and thicker passenger seat. The 2023 model year saw the Z650 get three-level KTRC traction control and full LED lighting for the turn signals and brake light.
The 2024 Kawasaki Z650 is available in Candy Persimmon Red/Ebony or Metallic Matte Dark Gray/Metallic Flat Spark Black for $8,149, with the ABS model available for $8,649.
