You did see they were 2 stroke engines, right.
Now if it was one of the billfold robbing 4 poker engines, it probably would throw the rod.
In the dirt bike & atv racing worlds, those new fangled 4 poke engine the OEM are offering, has drove the cost of racing up 4 times higher than what it was when everybody was running 2 stroke engines.
