Excitebikes

An Excitebike  is motocross motorcycle used in the Excitebike motocross championship. Excitebikes come in 80, 125, and 250cc engine displacements. Unique to the Excitebike series, each bike has a regulation rider activated turbocharging system. At any time during a race, riders can twist the left handlebar to activate a large turbocharger that increases the amount of air introduced into the piston chambers which increases the engine speed by three times, giving a boost of speed. However motorcycle engines are much smaller than the ones found in cars, and because of this can overheat very easily if pushed to hard. If used to long contentiously the turbo system can cause an Excitebikes engine to over heat, activating a temporary safety kill switch that shuts off the bike until the engine cools down. This can cost even the most skilled riders victory if not used carefully.
