Mick Walker's book Classic Jaapanese Racing Motorcycles published in 1991, state the following in the Tohatsu chapter, page 121. " ..the company announced that it was considering the sponsorship of a factory team for the 1964 European GP season...unfortunately, the idea was to remain but a dream..in February 1964 , the company was declared bankrupt. All the remaining racers, including spares, jigs, and tools were purchased by John Honda..Meanwhile after the bankruptcy, almost all the engineers formally employed by Tohatsu moved to the Bridgestone Motor Company" This implies to me that the unemployed Tohatsu engineers found employment at BS Motor. This doesn't imply a purchase of a bankrupt company.Walker states that the Tohatsu racing twin is the basis for the Bridgestone EJR-2. I disagree, I don't see enough similarities. The Tohatsu is an air cooled piston port design with 6 gears and the EJR-2 is water cooled dual rotary valve design with 10 gears.
