2024 Zx4r Top Speed. Sounds and feels like you're doing 100mph. — the km4000 mark ii claims to accelerate from 0 to 40kmph in just 2.9 seconds and has a claimed top speed of 120kmph, earning it 5th place on this list.
The 235 to 236 seemed and looked more stable on the indicated speed. All the goodies for true track rats.
