Originally started as an extension of my love for two wheeled (bicycles) sports, then motorcycles as a teenager...and never left my thoughts as casual weekend ride, of course cars were always foremost mode of transportation (a must). Gas crisis in the early 70's rekindled interest in motorcycles, that continues to this day.
The HD returned my interest into riding much more often, as it is so easy to ride at a relaxed or higher pace without stress. Metrics by design are a bit high strung with sharp "on/off power band" that requiries aggressive rider input, stirring the throttle/gearshift/braking demanding so much attention. Nowadays HD is more relaxing, joy every time a walk into the garage just to wake 'er up great therapy for the body and soul.
