I get it - and I understand what drives them.
There is a great Video/Documentary on YouTube which I watched at the weekend. I'm a big fan of the TT and have seen the Sidecars live on the island, it's an amazing spectacle.
It's called "A dangerous addition"

Give this a go, the correspondent struggles with it too, and he's a Biker.
They want to live life and push the boundaries, they know the consequences, just as every Biker does when you hit busy traffic - while I know the risk levels are off the scale on the TT we're all taking more risk than someone in an SUV.
So why do we do it?
