The T4A engine was still a three-cylinder two-stroke (simply a bored out version of the LC10), as Suzuki considered themselves experts at this configuration. The new Suzuki TC ("Two Catalyst") emissions system meant that it provisionally met the new 1975 (50年) emissions standards thanks to a two-way catalyst and a secondary air supply device. The downside was that the new engine produced a mere at 4500 rpm rather than the of the 360 cc engine it replaced. The layout remained RR, with a four-speed manual transmission. "7-S" was meant to stand for Space, Safety, Sense, Save money, Silent, Stamina, and Suzuki TC, not necessarily always in the same order. In January 1977, the Fronte received some light alterations including new seats, a rectangular Suzuki badge in the front grille, taillights of a new construction, and a slightly remodelled engine lid with a somewhat wider recess for the license plate. This model is sometimes referred to as the SS10-2, to tell it apart from the pre-facelift model.
