A few avid motorcycle riders revved up their engines for a good cause this afternoon.

Earlier today, bikes lined up at the South Lawn Shopping Center to participate in this year's Autism Bike Ride.

Riders could pay $25 to enter the poker run and bike show.

A portion of that money will go to two different Amarillo autism organizations -- Amarillo Area Autism in Action and Autism United.

A few avid motorcycle riders revved up their engines for a good cause this afternoon.

The ride ended with free food and drinks, all together making it a great and fun way to show support for a good cause.

Organizers say they hope to make this an annual event.
