At the centennial EICMA motorcycle show, Yamaha officially unveiled a new generation of R1,[14] similar to the contemporary YZR M1. Yamaha claims a wet weight of 199 kg (439 lb).[15] Engine changes include a decreased bore-to-stroke ratio, a larger airbox, a finger-follower valve system, and fracture split titanium conrods.[16] Magnesium wheels are standard, and information is presented to the rider through a user-customizable thin-film display.[16]

The new bike has an electronics package that includes a sophisticated Traction Control System (TCS), a Slide Control System (SCS), an anti-wheelie Lift Control System (LIF), linked antilock brakes, a Launch Control System (LCS), a Quick Shift System (QSS), and selectable power modes. The Slide Control System on the R1 is the first on a production motorcycle.[16][17] Information is fed to the bike through a six-axis inertial measurement unit and other sensors over 100 times a second.[17] Power delivery is tapered through throttle valve manipulation and ignition and fuel cuts.[18]

A second higher-spec, limited production model called the R1M is also produced, and is differentiated from the standard model by having more expensive components, such as electronic semi-active Öhlins suspension, carbon fiber bodywork, Yamaha's Communication Control Unit (CCU), a Y-TRAC data logging system, and grippier Bridgestone tires with a larger rear 200/55 size.

Starting in 2016, the lower-spec R1S model has also been offered.[19][20]

At EICMA 2017 Yamaha presented the next generation of R1 and R1M. They have a better Quick Shift System, an updated Lift (wheelie) Control System and fulfill Euro 4 requirements. The R1M got a new Öhlins Electronic Racing Suspension.[3] In 2019 next new models started.[4]
