The Bike/Snowmobile class is run on a Split Tree. Each rider can choose either a .4 Pro Tree or a .5 Full Tree. During time trials, riders will be split into two groups. However, during eliminations, the default tree will be the .5 Full Tree. Riders choosing the Pro Tree are required to place a “P” at the end of their dial (10.05P). A symbol will appear in front of the dial posted on the scoreboard before staging. There will be NO re-runs for incorrect tree configurations.
