While the same liquid-cooled, DOHC, 16-valve, 1,043cc inline-four remains, the 2019 Versys is the first Kawasaki model to feature an ECU-controlled Electronic Throttle Valve system, eliminating throttle cables in lieu of an accelerator position sensor located in the throttle grip. I was pleased to find the twist grip spring tension feels very natural, and the ride-by-wire throttle mapping deals out extremely smooth and linear power delivery. Kawasaki claims the engine produces 75 pound-feet of peak torque at 7,500 rpm but curiously chose not to provide a horsepower figure. My seat-of-the-pants dyno suggests peak ponies are fairly mundane for a liter-class inline-four. It's evident this engine has been tuned for ease of use and exhibits an over-rev that feels very much a product of the throttle map. While I didn’t get confirmation from Kawasaki, it felt to me that the throttle closes slightly as you near redline, a trait that is particularly evident in lower gears as it lays down at 9,500 rpm and eases up to the 10,000-rpm rev limit. Heck, you can even keep it pinned at the rev limit and the engine zings along contently. While the over-rev strategy may be a viable refinement, you best short-shift if racing for pinks.
