Zac Efron Wowed by Tom Cruise's Bike Collection

Zac Efron is still pinching himself after landing a dream tour of Tom Cruise's motorcycle warehouse from the man himself.

The actor has no idea why Top Gun star Cruise singled him out for a day of bike talk - but he happily joined Cruise and picked up a handful of helpful hints.

The two stars met at the offices of their agent and Cruise invited the High School Musical star over to his house for a guided tour.

Efron tells Details magazine Cruise also taught him how a motorcycle engine worked, and showed him the hangar which houses his collection of two-wheeled wonders, including the Triumphs he rode in the Mission: Impossible movies.

Star-struck Efron says, "It's just so cool that he gave a s**t, the fact that he cared at all."
