The 2021 Canadian Rotax MAX Challenge Technical regulations have been posted on the REGULATIONS page.
Here are the main differences from 2020 (not exhaustive):
- wording improvement and corrections
- battery with or without cable support
- precisions on the two legal wire harnesses allowed
- precisions on the exhaust mat
- for national events (ex. Canadian Open), only the red spark plug cap and black coated crankcase are allowed.
Please take time to read the regulation 2021 carefully.
