Pro Stock motorcycles are custom built for racing.  They are similar to street bikes but have more powerful engines, light weight tubular steel frames, and an aerodynamic chassis.  Bikes reach upwards of 195 mph and races end is less than 7 seconds.  The front wheel is for steering, the rear one is larger (10″ wide) to provide maximum grip on the track.  A “wheelie” bar prevents the bike from flipping.  Riders wear padded leather suits, gloves, boots, and a helmet for protection.  Xtreme Fact boxes state additional facts such as the tires only last about 8 drag strip runs and that acceleration force is similar to the lift off of the space shuttle!  Several racers are mentioned with their statistics.  A glossary is in the back but the words are not indicated within the text.  An index is also included.  Photographs show details on the bikes as well as action during a race.  Those attracted to sport bikes will be drawn to this series.
