I’m not sure why this is news? This is not even close to fast for a female drag bike rider, there are numerous female professional drag racers regularly running considerably faster than this. I think pro stock rider Karen Stoffer is currently the fastest running well into the 6’s. And with the pro street bikes (the class Ms Butler appears to be competing in) now dipping into the 6 second range she’s a way off the pace there two.
Still if she’s having fun more power to her (both figuratively and literally)... and as you point out she is considerably faster than me.
