What are the rules regarding the bikes in super cross and motocross? What is regulated?
Is there a minimum/ maximum weight in each class?
How about rwhp is that checked and is there a maximum
Do they run a spec fuel or is that open
Are there any electronics in the top levels, traction control, trick suspension like in the new track cars..those Multimatic units that electronically adjust in milliseconds
I have watched a lot of the races over the years but don’t remember anyone talking about it, figured some of you guys would know.
Thanks

To the best of my knowledge
There is a weight limit
No HP check max or minimum
Fuel is tested
Electronic controll of suspension and traction is not allowed.

Start with a allocated stock bike and build up from there.

Bet you know the keys to the race and what makeup to mud is. I've always wished (since bailey) the broadcasts spoke to us like informed fans rather than a family new to the sport. Stop trying to "grow", and speak instead to the true fan.

Frame and engine cases must be oem, you can add but not take away so coating the cases and bracing the frame is fine, no hp limit, 250 212lbs 450 220lbs.

The gp stuff youll see cairolli and Herlings have 2 diff frames, the ram air kawi I believe would be legal but you dont see it for brand identity/marketing purposes, the carbon subframe the gp yamahas would be illegal. Besides that you can dlc coat tranny gears, cams, pistons, suspension, add fuel injectors, frame bracing to stiffen but you cant add flex, really still a lot you can do.
