Predictable steering is unmistakable due to its 25 degrees of rake and 3.9 inches of trail. The combination of larger than average trail numbers and peculiarly narrow triple clamps require a heavy push on its handlebars to turn the bike quickly, while the triangulated profile of the Dunlop tires complements the bike's geometry perfectly, allowing it to reach maximum lean angle quickly and effortlessly. Although initial input is heavy, once leaned over the handling is neutral and the profile effect of the tires is very noticeable. Compared to early models, the new ZX-7 has better throttle response and midrange acceleration. The main reason for these improvements is the reduction of the intake ports by 4mm.
Smaller ports allow for better intake velocity and fuel atomization.
The increased velocity pulls a better signal at the carburetor's needle jet, allowing for excellent carbonation. Other improvements over the original formula include Muzzy's touches in the form of strengthened crankshaft, two springs per valve and a special baffle in the joint pipe to maximize exhaust pulse effect for more torque. Low and mid torque was improved with a balance pipe connected between the number one and number four header pipes. The head itself was refined with straighter ports, aiming the 38mm carbs at 50 degrees into the combustion chamber. Kawasaki has now fitted the ZX's transmission with involuted splines on the input and output shafts, allowing for less backlash.
