Buyer's Guide: 2021 Kawasaki Vulcan S, ABS, and Cafe ABS

The three-model Kawasaki Vulcan S family returns for ’21, with no changes other than colors and a $100 price increase across the board. Returning is the Ninja-derived 649cc DOHC powerplant fed by a pair of 38mm throttle bodies.

One of the Kawasaki Vulcan S lineup’s leading features is its dedication to Kawasaki’s Ergo-Fit concept. You can configure the Vulcan S to your dimensions. There are three available footpeg positions (the forward and rearward are one-inch different from standard), a reduced-reach handlebar that moves the grips 1.7 inches closer to the rider, and seats with three different rider positions. Further, the reach to the hand controls is also adjustable.

With sportbike performance from the motor, and a low-slung chassis with a spacious 62-inch wheelbase and generous 31 degrees of rake, the S offers a stable ride. Dunlop Sportmax D220 tires ensure that you can lean the cruiser to its limit with confidence.

The Cafe ABS version distinguishes itself from the S and S ABS with a tinted windscreen and model-specific paint.
