If and when you have the chance do it!
I had been to Scotland four times with "public transport" but I needed and wanted to go there on a bike.
Fortunatly my older brother agreed and we took of in april 2004.
It was cold, wet and BEAUTIFUL. There are some roads there that God seems to have made for motorbikers!
I did a 13 day 5000+ km trip and loved every minute of it
Grtz.
