Yamaha have this evening unwrapped the 2015 YZF-R1 on which Josh Brookes will try and conquer the MCE British Superbike Championship next season, ridden onto the stage at the Milan Show by Valentino Rossi.
A compact and new inline four-cylinder four-valve crossplane engine develops 200PS without the use of ram air induction, and delivers a strong pulse of linear torque for outstanding running performance - while the new short wheelbase chassis benefits from weight reducing features such as a magnesium subframe and magnesium wheels in order to achieve a wet weight of only 199kg - with a dry weight of 179kg.
The application of cutting edge MotoGP-derived electronic control technology represents a major leap forward in superbike design, and sets the new YZF-R1 apart from its peers. By monitoring every byte of data coming in from multiple sensors in the engine and chassis, the new R1’s advanced electronics enable riders to achieve the very highest levels of engine and chassis control.
Featuring the first ever six-axis Inertial Measurement Unit (IMU) ever featured on a street-legal machine, the new R1 represents the dawning of a new digital era where all riders can experience total 3D controllability.
Fully equipped with banking sensitive Traction Control, as well as Slide Control, Front Lift Control, Quickshifter, Launch Control, ABS and a Unified Brake System – and much more – the next generation R1 introduces racers and track day riders to a new era of rider-adaptive performance.
Ex-racers Giacomo Agostini, Noriyuki Haga, Fabrizio Pirovano and Alex Gramigni were in the audience while Jorge Lorenzo gave his rival a hand on stage.
