This song sounds like some dude in his basement with some toy instruments. I seriously don't know what instruments he uses in this song. Despite the poor sound quality and that of the vocals and the strange instruments, this song gets stuck in my head and I kind of like it. Its catchy.
I don't know exactly what the lyrics say but from what I can gather, he is using the speedy motors as a transitory metaphor. He describes many situations in his life by comparing them to a speedy motor cycle.
"Speedy motorcycle of my heart."
I just listen to the song I again and I got it all wrong. Oh, well.
