CONQUER ROAD
Yamaha has a rich heritage of building the most sought-after supersport motorcycles designed to deliver the pinnacle of performance on and off the track. The 2020 Yamaha R1 is forged from the technology and development gained from countless racetrack challenges, from MotoGP to the Canadian Superbike Championship. From crossplane crankshaft engines to revolutionary electronics such as the six-axis Inertial Measurement Unit (IMU), Yamaha's historical achievements have become the future of R World. |
REFINED CP4 ENGINE

The new 2020 R1 comes equipped with the next generation of Yamaha's unique 998 cc inline four-cylinder crossplane crankshaft (CP4) engine for refined performance. Returning features such as titanium fracture-split connecting rods and offset cylinders contribute to a responsive and potent character, while the cylinder head, fuel injectors, finger-follower rocker arms, and camshaft profiles are new for 2020. |
RACING PEDIGREE

Based on 22 years of proven race-winning engineering, the 2020 Yamaha R1M and R1 are forged from the technology and development gained from countless challenges in MotoGP, World Superbike, and MotoAmerica Superbike races, and the grueling demands of Endurance World Championship racing. |

MULTIFUNCTION TFT SCREEN
The R1 features a brilliant full-colour, thin-film transistor (TFT) instrument screen, with front brake pressure and fore/aft G-force readouts, giving the rider even more feedback from the machine. Choose either the street or track display mode, the latter of which focuses on performance information such as YRC settings (including new Engine Braking Management and Brake Control systems), a zoomed-in view of the tachometer in the upper rpm range, a lap timer, gear position indicator and speed.

Ultra-lightweight, compact, 998cc, DOHC, 4-valve, liquid-cooled, in-line four-cylinder engine with "crossplane" style crankshaft.
- The key components of this cutting edge engine design are the "crossplane" crankshaft and an uneven firing order. Both of these features are used on Yamaha's race winning M1 MotoGP racer. The R1 crossplane crankshaft locates the center two rods at a 90 degree plane from the outer cylinders. Instead of the crank pins aligned on the same plane (a straight line drawn through the center of the crankshaft), they align on 2 planes in the form of a cross... or "crossplane". Working in conjunction with the crossplane crank is an uneven firing order. This R1 engine fires 1,3,2,4 cylinders and the firing intervals are uneven at 270 / 180/ 90 /180 degrees. What all this means to the rider is the most linear torque possible and amazing throttle control. This engine design allows a whole new level of rider - machine communication. One of the most important benefits is the outstanding cornering performance that exceptional throttle control allows.
- The key engineering goal for the R1 series is significant horsepower with excellent controllability, making the bike easier & more enjoyable to ride. The R1 is a "rider's machine".

- lower end "cap" of the rod is made from the same piece of material as the upper portion; the 2 pieces are "split" apart using a special process known as fracture splitting & then machined
- fracture splitting ensures true big end roundness & greater precision in con rod dimensions for excellent durability despite the high horsepower loads
- lightweight titanium design (60% lighter than a conventional steel con rod) reduces horsepower losses & provides faster throttle response
- fracture split "Ti" rods are a world's first to be used on a production motorcycle
-
Single axis balancer shaft.
-
Crankcases feature a "Tri-Axis" layout for the crank, main and drive axles.
