World Champion Yrjo Vesterinen's 1977 Bultaco Model 199 Sherpa T Works Prototype

Yrjo: All of the works bikes were given new identities before they were shipped to the States. At the same time new bikes were given to us to use in Europe and those were stamped with the original numbers of the bikes being sent to the States.Hence the markings of the ground off previous numbers. Technically you could not have two bikes with the same set of numbers. That would have been breaking the law.
