Kawasaki Ninja H2R Top Speed: The 400 km/h Run Explained

The Kawasaki Ninja H2R reached a reported 400 km/h—approximately 249 mph—during Kenan Sofuoglu’s specially arranged speed attempt on Turkey’s Osman Gazi Bridge in June 2016. That achievement describes a particular run, rather than a guaranteed top speed for every H2R in every situation.

Where Does the 400 km/h Figure Come From?

The figure comes from Sofuoglu’s bridge run, which was reported by the Turkish Motorcycle Federation and WorldSBK. The attempt involved preparation and a controlled setting.

When discussing the H2R’s top speed, this context matters. A documented speed attempt tells us what happened during that event. It should not automatically be presented as the result every rider or motorcycle will achieve.

How Fast Is 400 km/h in mph?

400 km/h converts to approximately 248.5 mph, usually rounded to 249 mph.

Both figures describe the same speed. Including kilometres per hour and miles per hour makes the result easier to understand for readers in different countries.

What Kind of Motorcycle Is the Ninja H2R?

Kawasaki describes the Ninja H2R as a closed-course hypersport motorcycle. It uses a supercharged 998 cc four-cylinder engine.

Its intended use is an essential part of any performance comparison. Readers comparing the H2R with other motorcycles should consider whether those bikes are designed for the same type of use, rather than comparing a maximum-speed figure alone.

Does Every H2R Reach 400 km/h?

The reported bridge run does not establish a guaranteed result for every H2R. To compare another test with it, readers would need to know the motorcycle’s configuration, the conditions and the measurement method.

A useful top-speed report should identify the model year, explain how speed was measured and state whether the motorcycle was standard or modified. Without that information, two headline figures may describe very different tests.
