It is something that we have expected ever since we heard of Yamaha’s intent to bring two different variations of R1 to market, so it should come as no surprise then that the Yamaha YZF-R1M has been homologated by the FIM for use in the Superbike & Superstock 1000 classes.
Actually both flavors of R1 have been given the nod by the FIM, though we know that if given the choice, teams will choose to develop the YZF-R1M over the base model, especially as it comes with upgraded suspension pieces and carbon fiber fairings.
