'CHiPs' Erik Estrada on motorcycles: Don't look…

The next time you see see actor Ed Harris cruising down the highway on a motorcycle, know that he learned the art of looking good on a motorcycle from the best.

CHiPs star Erik Estrada gave Harris a personal training lesson on the motorcycle in the late 70s when a struggling actor Harris made a guest appearance on the show.

The unlikely screen duo now voice helicopters in the Disney animated film Planes, which dropped a new trailer on Tuesday.

But it's not the first time they have worked toget

her. Estrada couldn't help but to talk about schooling the now four-time Oscar nominee when Harris was on the CHiPs set. Harris was playing a one-off bad guy on the supremely popular California cop show.

Estrada, of course, was at the height of his Hollywood power playing highway patrol man Ponch on the series.

"I remember he didn't know how to ride a bike at the time," says Estrada. "(Harris) asked me, 'How do I ride this?' I told him it was easy, that I had never ridden a bike before until I came onto CHiPs."

His advice to Harris: "Don't look down and stay in first gear or second gear. Just go slow," Estrada recalls. "He did really well. He rode that bike. And he's gone onto a great career."

Estrada's other rules of the road: "Sit up straight, don't slouch and smile." These are words we can work into all aspects of our life really.

Naturally, Estrada also recommends keeping the best equipment such as gloves, boots and and a helmet.

"There's only two kinds of motorcycle riders," Estrada says. "Those who have been down and those who are going down."

Estrada still rides his Harley-Davidson Road King with the Blue Knights International Law Enforcement Motorcycle Club. He no longer cruises on his CHiPs mobile. But he does have one of the originals from the show, a gift from the Teamsters as a parting show of thanks. The bike sits in a place of honor in Estrada's guest house, right next to the pool table.

Estrada himself is looking good in uniform ! as the 1980s RadioShack commercial proved during the Super Bowl. He keeps in shape with 45 minutes of treadmill work daily. But he admits it's not the same motorcycle cop uniform.

"I had to let it out a bit," says Estrada, who just turned 65.

Even his aging secrets speak like a man who still knows how to ride on the road. Take note Ed Harris: "I'm Latin, I'm well-lubed," says Estrada. "And I color my hair."
