The story of the Bultaco brand is about as cool and inspiring as the motorcycles they produced. It started in the mid 1940s, when a road racer named Francisco Bulto co-founded the Montesa Company and began work on a light weight 95cc bike. The small two-stroke had no rear suspension and was far from ground breaking, but its moderate success was enough to spur on the design of a successor that featured a 125cc engine and a semi-enduro suspension for the 1951 International Six Days Enduro race. Unfortunately, by 1957 the company was facing a difficult financial position and made the decision to withdraw from racing. Outraged, Bulto resigned with several other employees, and founded a new company, called Bultaco, in less than 6 months. Named after the Spanish word for whiplash, the Tralla 101 took seven of the first ten places in the Spanish Grand Prix just two months after being released, kicking off the Bultaco legacy and laying the foundation for bikes like this awesomel 1973 Alpina.
