The new R1's front becomes more and more sharp breaking wind more ambitious, and position angle LED lights, the end of the muffler and heat shield has been redesigned. There is a new glasses, designed from YZR-M1. Table setting display panels built traction control, additional fire burning dead pedal also been improved to increase the contact surface of boots, enhance communication between people and vehicles.
Fiftieth anniversary Special Edition:
To celebrate Yamaha world war Grand Prix racing up to five years, the new R1 also has pearl white with hot pink 50th Anniversary Special Edition. Special Edition only two thousand units, embedded with the fiftieth anniversary of the birth of medals and number on the cylinder, the whole car with Yamaha Gold, vehicle also comes with a small sticker, even more collectible.
Cross-type engine CP:
Ultra-high performance 998cc four-stroke water-cooled straight four engines, power plants come close MOTO GP car M1. With the new design aluminum Delta Box frame, Yamaha once again founded a new public standard upgrade sports car. It is encouraging people YZF-R1 engine crankshaft using the crankshaft design factory car M1( previous levels seen only in car V8 engine) of the cross-plane crankshaft engine Cross.
What is cross Crankshaft? It is meant cross-shaped cross-section of the crankshaft. Generally parallel four-cylinder crankshaft word shape were tested, while in 2009 YZF-R1 is the first time using the V8 engine crankshaft cross! Cross-Plane crankshaft in the end what good is it?
Features can be realized asymmetric intermittent ignition time, drivers have more initiative to produce torque.
The entire engine crankshaft is the only power output shaft, so-called engine speed is the speed of the crankshaft, the engine crankshaft can be regarded as one of the most important parts. Crankshaft is called crank, it is because it is not a pass-through from beginning to end of the shaft, so that arm up and down in order to provide a linear motion of the piston into rotational movement of the crankshaft must be designed to be a number of twists and turns of the piston shaft according to.
The twists and turns of the crank( eccentric portion thereof) connected to the piston rod big end, called the crank arm; and crankshaft main bearings of the crankshaft is supported in the central axis of rotation of the crankshaft. Crankshaft beside each crank arm has a similar semicircular crankshaft counterweight so that operation of the center of mass of the eccentric crank arm it can fall on the center of rotation to eliminate vibrations caused by the operation of eccentric.
Traditional straight four engine ignition interruption time is 180o - 180o - 180o - 180o, One, fourth cylinder and II, III cylinder divided into two groups activities. The four cylinders YZF-R1 is independent operation to 270 ° - 180 ° - 90 ° - 180 ° asymmetric intermittent ignition parts to reduce inertia torque, so that the driver can have more initiative, more use of the throttle precision fabricated torque.
Four cylinders R1 completely independent, except when there is abundant low rpm torque than in the whole area has a good number of rotations in linear performance. To cope with asymmetric ignition interruption, the new R1's oil program also be amended accordingly, to develop four separate fuel supply and ignition timing. Of course, with the new R1 damping balance shaft, to be honest, only a fool would like tremors it:)
In other words, R1 riders can make in the case of the body tilt, more accurately manage and use high-powered, has a greater advantage at the apex and out of the corners. With Delta frame, tail and head and tail rocker suspension system, R1 will be able to more sophisticated forms, and more accurately regulate the distribution center of gravity. Cross Crankshaft addition to more accurately control the torque addition, the exhaust sound character is more and more attractive.
YZF-R1 engine compression ratio is 12.7: 1 Bore stroke are 78.0 mm x 52.2 mm, bore ratio up to 1.49, is super over-square supercar set. R1 peak horsepower( naturally aspirated mode, excluding ram-air mode) is 182ps / 12, 500rpm, torque is 11.8kg-m / 10, 000rpm.
Yamaha was the first depot dare enough strength to cross Crankshaft run on commercially available sports car. A commercially available sports car will not run again will have someone to overhaul the team, so you want to show a stable, accurate calculation and requires considerable support. This facilitates demonstration of strength to Yamaha to that next level. R1 other high-tech accessories, such as high-rigidity lightweight forged pistons wow guy or a titanium alloy foot, specially coated ceramic material synthesis temperature of the cylinder wall wear, are of course not to mention the inevitable deals.
