1972 - 1979 Suzuki GT 380
The 1972 Suzuki GT 380 showed much promise, on paper at least. If the other Japanese manufacturers had stood still during the 70`s then the GT 380 would have made perfect sense. The GT 380 saw some minor improvements every year of its production; this was never enough to bring it to the forefront of the capacity class.
NGT380 version (384cc)
In italy the very popular GT380 underwent a transformation from 1975-1979. Due to law and also the registered name "GT380" by Ferrari, Suzuki was compelled to change the model name in the country, thus it changed to NGT380 (or New GT380).
this version became a more desired version in hindsight due to the higher engine capacity (increased from 371cc to 384cc) which gave the bike more power and torque (41ps instead of 38ps)
The NGT was exclusivly distributed by Italia SAIAD S.p.A. - Via Cassini 89 bis - 10129 Torino (Turin) , Italy
