"Avengers: Age of Ultron" will see Black Widow riding the first ever electric Harley Davidson, according to reports.

The motorcycle was spotted on the film's set and would be used in the film as Black Widow's vehicle, reported Comic Book.

This is not the first time that Harley is teaming up with a superhero franchise. The company had earlier partnered with the two "Captain America" films and the first "Avengers".

The role of Black Widow in the Marvel Cinematic Universe is played by Scarlett Johansson and, now with the new reports, fans cannot wait to see Johansson riding a Harley in "Age of Ultron".

It is also understood that Black Widow's costume is going to have some additions in the "Age of Ultron". The character will reportedly feature a "TRON-style" look that will have electricity flowing through it. Thus, the enemies of Black Widow will get electric shocks, if they try to mess wit her, reports suggest.

Meanwhile, Robert Downey Jr., who plays Iron Man in the Marvel Cinematic Universe, recently sent his fans into frenzy, when he posted on his official Facebook page that he "just wrapped the Avengers: Age of Ultron gig".

In a recent interview to Variety. Downey Jr. had suggested that someone younger should replace him as Iron Man.

"The smart money is you have to look at everybody's age. I'll put myself at the top of the list. Sooner or later, they've got to start over and get somebody young. I'm not there with them yet. It really is the closest thing to being a beloved contract player with a big old-timey studio that there is right now," the actor said.

"When you really think about it at the end of the day, these films are entertainment largely driven by young folks. There is something very honorable about that. I run into kids wearing "Captain America" masks. My kid believes that Captain America is real."

However, there is one person who would like to see  Downey Jr. continue playing Iron Man - Jon Favreau, the director of first two "Iron Man" films.

"I think people would love to see Robert Downey continue the Iron Man character," Favreau expressed his views to Flicks And The City at the premiere of his new movie, "Chef".

"But he's done it quite a bit now. I've had a few movies off, so it's a lot easier for me to say that it should be done. I hope he continues doing it and, as long as he fits in that suit, there's no reason he shouldn't."

"Avengers: Age of Ultron" is slated to release on 1 May 2015.
