An important change for the 1974 MY was the "unitizing" of the [[carburetor]]s on all of the three cylinder machines. For MYs 1972 and 1973 the carburetors had been three separate items with the complex cabling that such an arrangement entails. The unitized carburetors were mounted to a single bracket with a much less complex single push-pull cable arrangement. This arrangement allowed easier and more durable synchronization of the carburetors. This practice was continued through to the end of production of the three cylinder models. At this point the GT750 received the new Mikuni BS40 type diaphragm style carburetors. These proved to be somewhat troublesome but were eventually sorted out with some remedial jetting work in the field. All the smaller models stayed with the tried and true [[Mikuni]] [[Mikuni VM|VM]] type round slide carbs.

The 1974 MY also saw Suzuki introduce the GT125 to the motorcycling world. This model was similar in layout to the GT185 but with a shorter wheelbase and smaller engine displacement so shared only a few common parts. The rest of this model's equipment followed that of the GT185. The electric starter was deleted, probably in the interests of economy, which allowed a more attractive selling price in the very competitive "beginner" market that this model competed in. This model continued basically unchanged, excepting colours and trim items, until the end of production with the 1977 MY. Some markets may have received 1978 MY versions of this model but there is currently no evidence supporting this assertion. This model was never marketed in North America so was not assigned a marketing name like its larger siblings.

Another marketing anomaly concerned the GT380. The actual engine displacement as introduced in the 1972 MY was 371cc and the 380 stayed this way until the end of production for most market areas. However, for the Italian market only, the GT380 received a displacement increase to 384cc starting with the 1975 MY. This engine size was continued through to the end of production for Italy alone. This was a counter to an Italian government import ban on bikes less than 380cc and less than 170 kg. Suzuki simply increased the bore of the GT380 to 55mm thus making the engine capacity now 384cc. Suzuki also made sure that the data plate riveted to the frame showed a weight of 171 kg.
