Hakuchou Custom
The Shitzu Hakuchou Custom is a new sports bike, which is exclusive to the downloadable episodic pack The Lost and Damned for Grand Theft Auto IV. It is a custom version of the Hakuchou, another motorbike manufactured by Shitzu. Like it's stock counterpart, it is based on a Suzuki Hayabusa. It is possibly the fastest motorcycle in the game, being faster then the Bati 800 or Bati Custom.
The Uptown Rider, DeSean, uses this bike for his transportation.
