LOOK THIS !!!2018 Yamaha R1S Design Overview Price & Spec - 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”.
