Then, took a loan bike out recently while mine was serviced. Same feeling, the right bar closer than the left. Then realised - I broke my left arm as a kid, and it's got a slight kink in it - therefore that arm is stretched out more than the right arm, meaning the right arm feels more "cramped".
So, it's not the bike that's twisted, it's me!

(Notice I didn't suggest "I'm bent" - I know what you lot are like
