The Yamaha RX-S 100 introduced in the RX models but with an energy induction in 1980s. In 2009, Yamaha introduced the first production in-line four cylinder with a cross-plane crankshaft orientation, technology derived from their MotoGP racebike. Also in 2009, Yamaha released their new model of sportbike based from the previous R6 motor. This new model is known as the FZ6R. The FZ6R with 600cc and a newly designed fuel-injected 4-cylinder engine is at the top of Yamaha's innovation.
