Xtreme Bike and Sled
This class caters to race and street bikes/sleds running 7.00 and slower. You get 2 qualifying attempts on Saturday before eliminations with the same format on Sunday. Rules are pretty simple and are as follows:
The Xtreme Bike and Sled class was designed for all bikes/sleds that run 7.00 and slower in the 1/4 mile. Open exhaust and lettering/decals permitted. Competitors get 2 rounds of qualifying. You choose your dial-in for eliminations. This time will be yours throughout eliminations (IT DOES NOT CHANGE and any competitor found changing their dial in WILL BE DISQUALIFIED).
The class will be qualified by positive reaction time (r/t) closest to “.000” based on a Pro .400 Tree. “.000” is considered perfect. Any negative r/t (-‐.001, -‐1.231, etc.) will be placed at the bottom of the qualifying ladder, the more negative the r/t is, the farther down the ladder the run will be placed. For cases in which identical reaction times are made, qualifying position will be based on a first-‐come first served: the first occurring r/t will be placed #1, the second occurrence of said r/t will be placed #2, and so on. Class will be paired according to qualifying positions, and then advance to eliminations.
