What is the top speed of the Kawasaki H2R?

[LaWilliam]

The theoretical top speed of the Kawasaki H2R is 420 km/h at 16,000 rpm; currently, it achieves 400 km/h at 14,500 rpm. Below is some relevant information about the Kawasaki H2R: 1. Working Principle: (1) Intake: At this stage, the intake valve opens, the piston moves downward, and the mixture of gasoline and air is drawn into the cylinder. (2) Compression: At this stage, both the intake and exhaust valves are closed, the piston moves upward, and the mixture is compressed. 2. Notes: The H2R is a pure racing motorcycle and cannot be driven on public roads; it is only suitable for track use. From a technical perspective, the wheelbase, though minimized, is still considered long. Most importantly, the 300 crankshaft horsepower needs to be linearized to suit corner exits on the track. Unless Kawasaki completely disables the supercharger mode, reducing the horsepower back to the naturally aspirated 200, developing a supercharged power electronic control system at a civilian price point would be challenging.
