The Yamaha YZF-R6 is a sport bike, produced by Yamaha as a 600 class from 1999 to 2020. From 2021, production availability is limited to a non-homologated race-only specification in most global markets, causing race organizers to realign their engine eligibility criteria to encourage other manufacturers having larger than 600 cc displacements to enter road-race competition from 2022. Race organizers wanted to provide scope for alternative machinery to move away from established tradition of the Yamaha R6 being the dominant marque in Supersport racing. A similar motorcycle currently in production is the Yamaha YZF-R9. This motorcycle is widely considered to be the R6's successor but this has never been officially stated by Yamaha.
