Mid '60s. An older neighbor kid got a Honda 50..I just loved all the plastic! I was 9 and obsessed...If I saw bike tire tracks, I'd walk on them and pretend I was riding...at about 10, after intense badgering, I hooked a ride on a guys Bonneville...I couldn't believe the acceleration! Then, I think later that year, I actually rode a real motorcycle by myself..a Honda Dream...ah, the squareness of it all! At 11, I got my first minibike, a Fox Doodlebug..I rode that thing through two engines, had a helmet that my Mom made me buy, but I NEVER wore it (I rode so much that I remember taking showers at the end of a week of riding, and there would be gravel in the bottom of the tub from my hair!)...went on to a second minibike and almost bought a Harley 45 military bike at 13, and rode all my friends Honda Mini Trails, mini bikes and motorcycles...I didn't really have a motorcycle until I was about 25 (after my first divorce)...an obnoxious Yamaha 250 Enduro...riding knobbies on the street improves your riding technique...Then I got married again...wanted a trailer hitch for the car..she (who hated anything I liked) goes "sell your motorcycle and you can get a trailer hitch"....Yeeessss Deeeaaarr....(wasn't as big a loss as you might think..that thing was a pain to ride...knobbies, geared down so the top end was about 60)....eventually, she got fired too, and within about 2 years, found my '76 CB750 and have nursed her back to vibrant health, and who knows, she may have siblings someday! No real influences, more like a genetic pre-disposition....no one else in my family has ever even been remotely interested in bikes.....
