Yamaha RS-100T Torque induction series, also known as RS-100 series, is a series of two-stroke motorcycle models manufactured by Yamaha Motors Co. Ltd as a successor of the Philippines' most popular 2T motorcycle/tricycle model. It debuted in 1977 especially for the Asian market (although it is identical with the original design of the RS-100 as produced for other markets from 1974 to 1977). While the older Yamaha RS-100 uses a pressed steel frame that also acts as the main body, the RS-100T uses steel tubes for the frames and metal cover sets for the body.

The Yamaha RS-100T comes in three displacement options - scooters, 100cc and 135cc. In addition to the three models that use carburetors, Yamaha also produces the fuel-injected 83cc model known as Yamaha.

By 2004, the RS-100T was succeeded by a more efficient and environmentally friendly Yamaha STX four-stroke motorcycle. In addition, the 150cc model includes a key slot cover for better protection against theft. Starting from 2007, the Yamaha STX in Philippines began using fuel injection system to replace the carburetors used by most of the Yamaha series.
