Orlando Bloom knows how to get our engines revving!

The sexy dad, who has been riding around town on his black Ducati, hit up a gym in West Hollywood wearing purple sweat pants by Free City. For a second, we thought he may have borrowed those pants from his supermodel wife Miranda Kerr. Kidding!

We're glad to see that Orlando never goes riding without his helmet. Wouldn't want him to mess up that pretty face.
