After the success of the Sherpa T, Bultaco released the Alpina 250, a bike specifically built for enduro riders. After 3 years, Bultaco offered a more powerful 350 variant, which you see in front of you. For more information on the 250 version of the Alpina, check out this article from Hemmings. Bikes like this helped Bultaco win the world trials championship nine times in eleven years. This specific example is claimed to be in great shape and that it’s got a new Mikuni carb.
