This 61ci (1000cc) board track racer represents the end of the board track era
It starts with Harleys best street engine but enhances performance using better breathing overhead valve racing cylinder heads and a racing chassis
Both board and dirt track racing called for direct drive with no clutch or transmission.
Racing starts involved push or pull starting the race bikes on the track
Keystone racers started with a full loop frame which was cut allowing the motor to become an integral part of the structure which allowed for better handling with a lower center of gravity
