Santiago Herrero is synonymous with the shamrock brand and will always be remembered as one of the best riders in history, who tragically, never won the world championship.
He was awarded his racing licence in 1962 and raced for Derbi and was his own mechanic. He then switched to a Bultaco Tralla 125 and later the Spanish make Lube hired him for their competition department. In 1964 and 1965 Herrero came third and second respectively in the Spanish 125 cc Championship, but soon after Lube went bust.
Herrero friendly manner, super talent and mechanical skills made him an attractive proposition to the OSSA factory and Giró offered him a job developing the OSSA 250cc race bike.
He worked harmoniously and effectively with Eduardo Giró on the development of the OSSA monocoque, which featured a 6 speed rotary valve engine and together they began to surprise the motorcycling world. On the OSSA 230 cc bike with no fairing and 30 HP, they won 250cc Spanish Championship in 1967.
