Butterfield (Willis 4) USA, Late 1960's early 1970's?, Butterfield owned Jacks M/C in Fresno California, a Ducati, MotoGuzzi , BMW Dealership, Willis worked with him in the mid 60's into the 70's. They built a complete motorcycle made to accept a 1500cc Volkswagen engine and used a BMW /2 transmission. The bike looked very much like a R60/2 BMW and was available as a kit or complete motorcycle. They are the best looking motorcycle I have seen that incorporated a VW engine. Apparently Butterfield and Willis had a falling out and a lengthy court battle ensued over the rights to the motorcycle and Willis won. Willis used a badge for them that said "Willis 4's" it resembled the BMW badge so closely that BMW threatened legal action.. Willis died shortly after. Approximately 100 were built. see picture
