i am unsure, but a road bike cannot legally have a top speed of over 125mph, not that you can go that fast any way.
Suzuki GSX1300R Hayabusa 190 mph (305 km/h)
The Suzuki GSX1300R, also known as the Hayabusa, is a hypersport motorcycle introduced by Suzuki in 1999. It has a 1299 cc inline-4 engine rated 175 bhp (129 kW), and was consistently tested as the fastest production motorcycle in the world. The name Hayabusa is the Japanese term for the Peregrine Falcon, known for its speed, and perhaps a joke at the expense of the Honda CBR1100XX Super Blackbird which was the fastest production motorcycle prior to the Hayabusa: the Peregrine Falcon is a predator of the common blackbird.
