Sugomi Styling Upgrade

The Z650 S features sharper Kawasaki Sugomi styling with a LED tri-lamp front end and large side cowlings that give it a genuine big-bike air, aligning it more closely with the four-cylinder Z900.

🏍️

Tweaked Riding Position

The Z650 S's bars are 40mm further forward, 10mm higher and 30mm wider than the standard Z650, with slightly more rear-set footpegs for a sportier yet comfortable stance.
