Fast and on two wheels with the speedometer spinning, reaching speeds of more than 300 miles per hour.
"Once I started riding motorcycles, it was like, that was it," said Valerie Thompson.
Valerie holds the record as the world's fastest female on a motorcycle, but you'd barely recognize her in her business attire. With high boots and every hair in place, it's certainly not messed up by a motorcycle helmet.
She knows all about these machines on two wheels.
Outside of her Paradise Valley home, Valerie's motorcycles are her prized possessions.
They're a far cry from the big wheel she rode as a little girl.
"I never raced anybody," said Valerie. "I used to race people on roller skates when I would go to the roller skate rink but I never...I didn't know I had that in me."
She worked in the banking industry for years, but after she was laid-off she was ready for her life to take a hard left turn.
So Valerie started racing motorcycles.
Her highest speed clocked at 307 miles per hour. It's so fast and so intense, she doesn't look at the speedometer when she's racing.
Controlling the streamliner bike with two fighter jet joysticks, Valerie says the ride is actually peaceful.
"It's just you and the machine. You don't have anybody chirping in your ears. You don't have a text message. You don't have your phone ringing."
Valerie and her team now have their sights set on an upcoming race in Australia.
This is a big one because she's hoping to break records and become the fast person on a motorcycle, ever -- topping speeds at 400 mph.
