Jason Momoa Rides Motorcycle Up Stairs for ‘Fast & Furious 10’

Jason Momoa is itching to play the villain in “Fast & Furious 10” … practicing stunts on a chopper and showing off some serious muscle in the process.

Jason jumped on hog that was attached to a camera and rode up a set of stairs in Rome.  When he got to the top he strolled back down, removing his jacket … revealing a tank top partially covering endless muscle.

Jason’s the newest edition to the F&F franchise. It’s a good time to be part of the franchise, because the 9th installment last year did super well … raking in $721 million worldwide.

The franchise has an insane list of stars, including Vin Diesel, Charlize Theron, John Cena and Idris Elba.
