NRG 900
The NRG 900 is the fastest motorcycle in GTA IV, and is very close to being the fastest land vehicle in the game. It excels at stunts and tricks, and is the only superbike in GTA IV. It is, however, difficult to turn.
Design
The design is similar to that of the NRG-500 from GTA: San Andreas. It is possibly a modernized version of the NRG-500.
The NRG 900 is based off of the Ducati 999R, but its headlight cover can differ between the 999 style cover and that of a Ducati 888's cover.
Locations
There is an NRG 900 dealership in Alderney around the border between Westdyke and Leftwood.
