[TD="class: alt1, bgcolor: #F5F5FF"]Heck yeah! Most of my experience and reply is regarding off road riding. Growing up, among the people I knew, the best off road racers were the ones who seemed to have spent the most time riding around on their bicycles - jumping, skidding, riding wheelies etc. This was before these kids ever got a motorcycle. Some would just try jumps over and over again on their (this will show my age) banana seat schwinns. Or sliding through turns, learning how to control a slide. We could always tell who was going to be best on a motorcycle by the way they rode their bicycle.
One of my best friends is a former pro motocross racer from way back. His advice to young dads, with young kids is get your kid a bicycle and let him learn to wail on that thing in the back yard, before ever worrying too much about purchasing a small motorcycle.
Not to cut down other opinions, but I think those that don't think the skills translate are overthinking the thing. It also goes the other way. Many probably know the story of off road racing legend, Dick Burleson, trying downhill mountain biking and winning the nationals not long after.
