This Japanese Motorbike simulator has plenty of realism that other games of this type don't.

You start of with a moped delivering packages to the other side of town. You have to drive your moped through a busy suburban city, where pedestrians and other drivers go about their business.

If you jump red lights or get seen speeding in certain parts of town you will get a ticketed. Every time you deliver the packages on time you can upgrade your ride.

Controls:

Mouse - controls direction and speed
There is a box on the screen with a arrow, push the arrow to the top for max speed and pull it back to break.

On the first screen pick the 3rd option to pick your first moped.
