The Ninja ZX-4RR reach 243kmph in the sixth gear (150.99mph). Interestingly, the motorcycle still has 500rpm on the tachometer, meaning there’s probably a bit more in the tank. But it’s worth noting the ZX-4R starts to fade out post 220kmph (136mph) and simply creeps to its top speed post this. Nevertheless, at 150mph, the baby Ninja is slightly faster than the Yamaha R7’s 143mph top speed while it beats the Ninja 650’s 131mph figure in the fifth gear itself.
