ORIGINALLY INVENTED AND PRODUCED IN 1978 THIS SIMULATION BOARD GAME HAS APPEARED IN A NUMBER OF FORMATS OVER THE YEARS, WITH RIDERS AND SPONSORS TAKING BATCHES IN THEIR OWN NAMES.

THE METHOD OF PLAY HAS REMAINED THE SAME EXCEPT FOR AN ANNUAL SPEED TABLE ADJUSTMENT AS LAP TIMES DECREASED AND SPEEDS INCREASED.

WE HOPE YOU WILL ENJOY SIMULATING TTs FROM THE PRESENT AND THE PAST, USING YOUR SLIDING SCALE SPEED TABLE TO CONVERT TOTAL THROWS TO MPH.

IF YOU LOOK UP THE LAP RECORD FOR A PARTICULAR YEAR AND SET THAT SPEED AS SEVEN THROWS YOU WILL BE SIMULATING THE RACE FROM THAT YEAR.
