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.
