I learnt to ride at 13.... learnt on a BMW R750 in a car park... then accidentally on purpose drove off onto the road...oops. Got the itch for bikes well before then, but learning on something that actually had a bit of grunt was the best way to make sure it never stopped itching... I remember riding my Rocket Roadster out to Alice with a bunch of guys...oldest guy there was 75 and going strong. He was on a Z900 - he said the only way he’d stop riding was when they put him a box in the ground. At 58 I know exactly how he feels.
