It's an annual competition that pits departments against each other, and it is all for a good cause.
It's the 19th Annual Southwest Police Motorcycle Competition.
"It is fun, and it helps me on my skills on slow maneuvering and control fo the bike," said officer Adam Gjelhaug.
"For the training, obviously you're gonna be a lot safer motor officer the more you train," said another officer.
The event is two days long, with the competition shifting into gear Saturday.
On Friday, the officers were able to come out, practice on the course, and work out the kinks.
"It's a little tough, as long as the floor is clean I won't fall," said one officer.
Awards will be handed out in different categories from speed, to make of bike. Organizers say it's not all about winning.
And not everyone will finish the course.
"This is the time to practice and push yourself to 100%, not out on the street, so they sometimes go beyond the 100% and that is when mishaps happen," said an officer.
On top of the benefits of training, all money raised goes to the Special Olympics of Arizona.
