Please name this late 60's-mid 70's film

I've been trying to think of this for years. I saw it on television a few times in the late 70's, although I don't know if it was made for tv or not. It had a lot of bikers in it and I believe they all turned to stone at the end. Not much but any ideas?

Did a simple google search "bikers turning to stone movie" and what do you know it gave me an answer. That google, it's new but it's good!

Like the fella says, in Italy for 30 years under the Borgias they had warfare, terror, murder, and bloodshed, but they produced Michelangelo, Leonardo da Vinci, and the Renaissance. In Switzerland they had brotherly love - they had 500 years of democracy and peace, and what did that produce? The cuckoo clock."

The trailer is a real trip. It is a British movie with George Sanders playing the butler!

That's it! Not sure I'd like it as much as I did when I was 9, but I'll check it out.

Thx!
