my first dirt bike! me and my dad took off the lights(front and rear)replaced metal fenders w/ preston petty plastic,knobby tires and then the sophisticated engine incarnation unto a race capable sl70 with top end and exhaust work capable of running down equally available equipment at local mid atlantic moto-x races.(very rare)I learned earliest skills of racing banging bars against people with superior equipment.The cool thing is that I learned to beat this bunch on outdated machinery.
