I wouldn't recommend this without reservations, but I passed my bike test at 40 and got a 1 litre adventure sport motorcycle.
I'd ridden bikes in my youth and have been a professional driver for most of my life. Knowing how roads work, how dangerous all the other fools on them are, and being used to the hazards on UK roads, I started off slow. Every car driver is a "didn't see you, mate" waiting to happen.
The freedom and joy of riding through North Yorkshire, the beauty of the place, the days out in the sun, and the people you speak to make it a massive thing in my life that I wish I could do more of.
