My dad always had bikes, and cars, and lots of things with engines and whirlybits,
got a DT50 when i was 16 as a way of getting around, got an XJ600 at 17, been doing it ever since, cheaper on fuel, tax and insurance than the car not to mention faster, plus its so much more fun, your not stuck behind a windscreen with radio 1 on in the background, if you ride through cow sh*t you can smell it and feel it through the handlebars, if its raining you feel it soaking your gear, it brings you so much closer to your environment
