Baseline
Gearing Information for Jr. Sprint & PP Can Road
Racing Classes
We are frequently
asked about set-up information, especially from
junior drivers. Carrying on the wonderful tradition
of Kopp Motorsports, we would like to share our
baseline gearings with those who might find them
useful. Consider these starting points if you are
lost or have no historical info to fall back on.
Different engine builders create KT100s with
different characteristics and air density can have a
significant impact on gear selection, so results
will vary. Data is from 2006 season unless otherwise
indicated. |
