pschrauber Posted January 29, 2016 Report Share Posted January 29, 2016 (edited) I have been checking an original Bultaco parts book special for official dealers, and in that book you can read that the first six speed Bultaco was frame number JB-19912885B. pschrauber, you talk about JB-19912876B being the first B model. Maybe those 9 bikes 12876B to 12884B could be prototypes for competition using the 326,2 cc engines 5 speed or maybe even 350cc with the older 5 speed gear box? The first one we have recorded at the moment is JB-19912920B in Palma de Mallorca, also another early one JB19912941B in Córdoba in southern Spain. The later ones still JB-19914912B in Bilbao and JB19914920B in Barcelona. To the numbers, as mentioned before, when Bultaco made up there system of frame numbers they should have had a system that is in itself logical. With new models they changed the first three numbers and started again with zero. With the model 199a and model 199b these were just models with "small" improvements, so they went counting up between model 199 up to 199b I think. I don't think that there were given double numbers in purpose, at least all vehicle data in Germany were already in the end of 70's recorded electronically and the data collected at the KBA (Kraftfahrbundesamt), once they were put in traffic, (not before). Same with the Italians which did punch the registration numbers below / under the frame number to the frame of the bike when imported as a single bike. Motorcycles with double numbers could be easily noticed later when set up for road and this done by the manufactor would be a crime. I believe when the reminding workers of Bultaco that didn't got a job after the bankrupty of Bultaco and were assembling bikes from piles of spares without superstition at the Derbi facilities as part of a social program of the state, may not have been precisely those that were easy to convey, thus couldn't count right ... hard thesis ... I know ... Edited January 29, 2016 by pschrauber Quote Link to comment Share on other sites More sharing options...
