However, the Kawasaki Z 400 2023 has a weakness in the form of non-adjustable levers, which may limit the comfort and customization options for some riders. On the other hand, the Kawasaki Z650 2023 has a few weaknesses, including not enough space on the bike for tall riders, a bike that looks a class smaller than its 650cc engine would suggest, an engine that may appear tame, a very defensive seating position, and handlebars that are too narrow and cranked too much for a naked bike.
