Japanese Domestic Market Frame Numbers
Suzuki used a Japan specific frame numbering system having a 'B' after the model designation (so GT750B-xxxxxx), although often the engines were pulled from the same production lines as for the export versions and used the standard engine numbering. I'm still collecting various Japan specific manuals and material. This section will expand over time:
JDM GT250 Production - Frame numbers covering the 1972 through the start of the 1975 model year of Japanese domestic market GT250 models.
JDM GT380 Production - Frame numbers covering the 1971 through the start of the 1975 model year of Japanese domestic market GT380 models.
Late JDM GT380 Production - Frame numbers covering the 1976 through the start of the 1977 model year of Japanese domestic market GT380 models.
JDM T500 Production - Frame numbers covering the 1968 through 1972 model years of Japanese domestic market T/GT500 models.
JDM GT550 Production - Frame numbers covering the 1971 through the start of the 1975 model year of Japanese domestic market GT550 models.
JDM GT750 Production - Frame numbers covering the 1971 through the start of the 1975 model year of Japanese domestic market GT750 models.
