TECH BULLETIN 12.15.21
For the 2022-2023 race season, the Stock UTV class will be allowed to make modifications to the rear plastics to accommodate the mounting of spare tires. Ultra4 will revisit this modification rule after the 2022-2023 season if needed.

ALL SAFETY RULES INCLUDED IN 2021 ULTRA4 RULEBOOK STILL APPLY

Quick note: We changed the way the rule book deals with changes this year. We got rid of the red color on changes because it was causing issues when people printed it on a black and white printer.
New format for changes in the 2021 book is: Strikethrough for deletions (same as past years) New text is underlined (no longer red)
