2015 Yamaha YZF-R1, Everything except the name has changed. MotoGP, the highest form of motorcycle racing, is our proving ground. The technology Yamaha has pioneered and proven on MotoGP circuits around the world can now be enjoyed by racers and riders alike. The all new R1 provides racers and enthusiast sport riders with a taste of what it would be like to ride the race winning Yamaha M1. A showcase of Yamaha's technology leadership, the all new R1 raises the bar with its uncompromised performance and handling.Engine FeaturesAll new, ultra-lightweight, compact, 998cc, DOHC, 16-valve (4-valves / cyl.), liquid-cooled, in-line four-cylinder engine with "cross plane" style crankshaft.The key components of this cutting edge engine design are the "cross plane" crankshaft and an uneven firing order. Both of these features are used on Yamaha's race winning M1 MotoGP racer. The R1 cross plane crankshaft locates the center two rods at a 90 degree plane from the outer cylinders. This means 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 "cross plane". Working in conjunction with the cross plane 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 increased engine control allows.The key engineering goal for the new R1 is increased power with excellent controllability. Horsepower increases have been gained through increased intake air volume, reduced internal friction and weight reductions. The new R1 is a "rider's machine".New, 4-valve cylinder head design features new compact pent roof combustion chambers that utilize lightweight titanium valves on the intake side. The 4-valve design optimizes breathing efficiency and overall engine performance. Combustion chamber volume is carefully monitored to ensure exact volume for maximum power.New, larger valves for 2015. Titanium intake valves are 33mm in diameter ('14 = 31mm) while the steel exhaust valves are 26.5 mm in diameter ('14 = 25mm). The lightweight titanium intake valves reduce reciprocating weight allowing for higher rpms without the concern of valve float.New intake port shape provides maximum filling efficiency. The port shape, valve placement and combustion chamber shape induce a tumbling effect of the inbound fuel - air charge that increases combustion speed, power and torque.13:1 compression ratioAll new "finger follower rocker arms" are used. This system reduces friction, allows greater valve lift and provides super accurate control of valve opening and closing at high rpms. The sliding area of the r
