INTRODUCTION
2.1 Game Description
Motocross Go! SD is a motorcycle racing game, linkable by up to 4 players, offering
competition on either a one-way (going/coming) undulating course or a round
course for two or more players.
Turning is accomplished by leaning the bike left or right. The handlebar is used to
make a small adjustment to the bike’s direction and to provide counter steering.
Accelerator and brake controls are provided on the handle assy.
2.2 Game Rules
.
.
.
The player needs to reach the goal as fast as possible within the time limit.
Players choose from three courses and select either of two bikes. In
Communication (linked) mode, the course is decided by a majority of players.
The game continues until the time runs out. In linked mode, if one of the players
participating in the same race passes the check point, time is extended.

PRECAUTIONS
3.1 Installation
This game is designed for indoor use only. The following conditions must be
met:
1. The game location must be free of direct exposure to sunlight, high humidity,
dust, high heat or extreme cold. If installed in an unusually hot location, allow
additional clearance between the rear of the game cabinet and any structure
which would tend to restrict air circulation.
Do not install in an area such that the game would present an obstacle in
case of an emergency (i.e., near fire equipment or emergency exits).
2. Vibration. Due to the considerable accelerations produced on the ride base by
the player, it is very important to make sure that both the cabinet/bike
attachment bolts and the leg levelers are installed and tightened prior to
operation.
3. Before operating the game, make sure that the main AC power hookup includes
a safety ground. This will ensure safe operation as well as compliance with the
applicable FCC and UL requirements.
4. Measure the AC line voltage [LINE to GND and LINE to NEUT] and verify that it is
between 1 IO and 125VAC. NEUT to GND voltage should be less than 1 VAC.
3.2 Handling
1. Before replacing any parts, turn the AC power OFF and unplug the game.
2. Do not attempt to repair the Printed Circuit Boards (PCBs) on-site. They contain
sensitive integrated circuit chips that could be easily damaged, even by the
small internal voltage of a multimeter. Always return the PCBs to your
distributor for any repairs.
4

Operator’s
MOTOCROSS GO!TM SD
Manual
3. The game monitor has areas of high voltage. Take care at all times to avoid
electrical shock whenever inspecting or adjusting the game. Before servicing
the monitor(s), make sure the game is unplugged.
Monitor
m Fly
back uansformet
4. Within the game cabinet ferrite clamps and shields have been included where
needed to control electric field emissions. Removal or relocation of either the
ferrites or shields will cause the FCC specification limits to be exceeded, and
may cause faulty operation of nearby susceptible equipment. Also, re-routing or
disconnection of grounds within the game system will result in excessive
emissions and/or a safety hazard.
5. Always return levelers to the extreme up position before moving the game.
6. Always re-install the bike lock plates before moving the game.
7. Always separate the monitor tower and bike base assemblies before moving the
game.

INTRODUCTION
2.1 Game Description
Motocross Go! SD is a motorcycle racing game, linkable by up to 4 players, offering
competition on either a one-way (going/coming) undulating course or a round
course for two or more players.
Turning is accomplished by leaning the bike left or right. The handlebar is used to
make a small adjustment to the bike’s direction and to provide counter steering.
Accelerator and brake controls are provided on the handle assy.
2.2 Game Rules
.
.
.
The player needs to reach the goal as fast as possible within the time limit.
Players choose from three courses and select either of two bikes. In
Communication (linked) mode, the course is decided by a majority of players.
The game continues until the time runs out. In linked mode, if one of the players
participating in the same race passes the check point, time is extended.
