West Valley Division episode

In this episode, Air-10 asks Adam-12 for assistance with a dirt bike rider because he might spark a brush fire. So Pete and Jim come across the rider and try to pull him over. During the "chase", Jim asks Air-10 if they have "run the bike" and Air-10 responds with the information. Name, address etc... of the rider. My question is this: How in the hell did Air-10 get the info? I cannot see how they could even see the license plate on the dirt bike!! Binoculars? I don't think so, with they way that bike would be bouncing all over the place, they'd never be able to read it!! Thoughts?
