You may not know yet what is the crankshaft in a plane, but will. It's a link to the bike for Motor GP Valentino Rossi, and it's greater progress in engine design liter-bike years ago.
This new arrangement of the crankshaft is part of the Yamaha YZF - R1 another, and we liter-bike testing last week to Eastern Creek circuit in Australia, she had not seen in the design of any production motorcycle earlier.
998cc distinctive sound of the engine is a clear indication that something special - it is closer to four with the fifth note, deeply meaningful, which seems a little angry. But this is the way in which the engine generates power that sets it apart from the competition. Gone is the pale power-band of the engine before, and his place is the most malleable liter-bike built after the four-cylinder.
Yamaha R1 for 2009 is ready to do battle against any of his rivals liter bike them.
Medium-term promotion of the newly is welcome, but more than that is the feel of a direct link between the throttle and the rear tires. In most liter bikes, rider is fully aware of the possibility of high-sided to the moon if the application of the throttle is unwise. With R1, so that the rider skilled moderate drift safely rear tire on corner exits.

What is the crankshaft through the plane? Crankshaft in a plane arranged by the Pistons had 90 degrees away from each other. We have power on earth ... It also drives high-performance motorcycles have grown more powerful, and it became difficult to harness the power through a small contact patch on the rear tires. A typical four-cylinder engine uses a flat plane crankshaft, and two external and internal pistons two rise and fall in pairs, with the exception of fire 180 degrees. Apply torque to the crank during combustion and, of course, but also of limbo as the crankshaft spins. This is the moment of inertia and noise of Engineers, and has effects of mixing between the rider on the amount of traction available from the rear tire of the bike. The same is true in the world of motorcycle racing, so I made the Yamaha engineers in 2004 varying period of time to launch the M1 are included in the four-cylinder with the so-called cross-plane crankshaft. In this new design pistons arranged 90 degrees apart from each other in all parts of the crank, which eliminates torque fluctuations in inertial model of the factory four-cylinder. The balance shaft keeps vibration to acceptable levels. This configuration is adapted Yamaha streetbike R1 for them, and to provide traction to promote and very distinctive exhaust note we hear from racebike Valentino Rossi. In the 600cc category and Super Sport 1000cc, logo always successful lighter and more powerful. But with the crankshaft 182 horsepower claimed, R1 is not reset the new bar in the production of energy. And the operation of 454 £ weight (full fuel, etc.) is 15 to lean on Honda CBR1000RR.
And R1 and configure the new engine will instill confidence in his rider.
Non-brake calipers, to pretty much everything you see here is a new Yamaha R1.
Instead, it focused on the concept out for Yamaha R1: "to provide as much as possible the power of the drive in the smoothest way possible." We are happy to report that this is not just some of the noise of public relations - is in fact something rider can feel after a short period in the saddle.
One of the knocks against the old R1 response lethargic when he left the traffic lights. Medium term and a new engine certainly help in this regard, and the help of two additional teeth on the rear sprocket. Quick launch no longer need the major slip clutch, which ride around the town much easier to manage.
In terms of structure and R1 does not break new horizons as far as its engine. Rake and trail remain unchanged, while the wheelbase shortened by 5mm slim. However, the framework is the R1 all-new design with revised rigidity balance significantly.
Made from a combination of flowers and attractive, and cystic fibrosis casting, aluminum, and leverage, and the frame is more solid in the head and guide the swingarm pivot, but the rails under the ocean are now 37 percent more flexible horizontally, and to provide greater feedback when the bike is leaned over in the corner. As was the swingarm rigidity balance tweaked, allowing more of kindness and horizontal torsional.
Around the circle of Eastern Creek, the new R1 has proved to be fully cooperative. In turn, a response about what it is and we've come to expect from liter-bike, and helped to some extent by using one of the longest series rear tires 55 instead of the 190/50-17 model. There are many mid-corner bumps on the race track Australia, Yamaha and is very adept in absorbing them without throwing the bike off the track.
Helps to keep things stable inhibitor is directed stylish. Like the previous model, and the inhibitor has a choice to engage the ball when it hit the handlebars back and forth very quickly. This helps the system by an electromechanical valve, which entered the new damper when the car exceeding the speed of 125 miles per hour or when it is twisted throttle past halfway.
Even with the tires in the streets, and encourages the R1 acute angles lean. We rode on Michelin, and the United States but the models will be equipped with Dunlop rubber in the new D210.
There is a new suspension system is completely up to the task of overcoming the ride. In the line of attack is a fork Soqi that its circuits, damping is divided between each leg. Been streamlined flow of oil through access to the left leg only deal with the pressure of damping and the tube right to control the rebound damping only. Yamaha representatives claim this design reduces the cavity (air mixing with oil). At the rear, and the suspension of the bottom of the link to have a more advanced rate to increase the use of her travel, in addition to the officer hydraulic preload makes putting the bike easier.
Allowed to revise the structure of the engine to be placed further forward in the frame, the shift in weight distribution slightly towards the front. To better focus overall, is now being less fuel between his legs and subframe racer and lightweight magnesium replaces aluminum component.
Projector headlights, unlike most headlamps sport-bikes' double, both of R1 remain lit in both the high and low beams.
In fact, the preferred mode standard, it also allows to respond in a smooth and surprisingly that the cooperative. Soccer - Application Mode the most sensitive to throttle a bit, but still be completely under control. B provided a more relaxed mode responses were not ideal for reducing lap times fast, but it would be a good choice when road conditions are a little suspicious, such as during wet conditions or wet. Unlike the Suzuki system, it is not neutered in response to engine power levels 600cc class.
The ability to get on the pavement, thanks to easy access of the new R1 engine.
And R1 in the Mikuni fuel injection system now includes 12 crater squirters, augmented by injecting secondary. As in the previous R1, Yamaha entrance space variable-length (YCC - I) will contribute to the expansion of its power-band. Funnels deal to stay in shape long without 9400 rpm, then flip open for a shorter period in order to promote the withdrawal of top-end.
Yamaha R1 says that produces 182 hp at 12500 rpm, which should be enough for one of horse riding in the street. But by the escalation of the gears on the spot along the creek east front, the Supreme Review Yamaha withdrawal does not feel as mind-numbing and something like this in 10R Kawasaki ZX -. The broader power-band made this new engine that he feels a little dull or its peak at the end of the day is not abundant, such as competition with them better. Regardless, the application of this unique configuration street-bike a new engine, preferably through a lot of the previous version.
The engine does not harm the performance of R1 race track, either. The Yamaha rider in the test Jeffry de Vries able to lap within the scope of Eastern Creek 1:37 on the latest R1. In the previous model, and was better for him in the lap of 1:39 is high. This bodes well for American Ben Spies, who will be riding a Yamaha in World Super-bike next season.
It should be noted that the specifications of American cycling produces less than six horsepower thanks to the Euro versions for smaller internal muffler to keep noise within the borders of the United States. Exhaust system is still the four-year-old two and 1-2 configuration, go to the dual mufflers titanium underseat, but now go without EXUP Yamaha exhaust valve.
A major break in the side of gift allows the hot air to escape. Titanium mufflers look a bit bulky.
In the use of the street and R1 now offers a more hospitable little ride. Handlebars of this program is 10mm closer to the rider, and the seat is placed 8mm forward. Located forward Footpegs 10mm, 15mm repositionable and are now up and 3mm rear. Just really fast riders will need to pegs in their more aggressive.
Governance
In my career of ten years or more in the field of journalism, Motor, I have had to sift through the vast amount of publicity public relations to highlight the incremental increases in most of them in the performance sport-bikes. Lose a few pounds here, in addition to two horse percent there. So it was with great joy that I found a significant shift in technology when you test the new R1, which provides progress in the real world in the design of the engine.
Arriving at dealers at the end of this month. Team Yamaha Blue version retails for $ 12.390. And an additional amount of 100 to buy any of the others, each with matching pinstripes on the wheels of their own.
We believe that the public relations hype this time. New Yamaha YZF - R1 provides liter-bike performance in a package of benefits not only the contestants, but also less-skilled pilots street. With the addition of the engine crankshaft in a plane, it is safe to say that Yamaha has upped the ante in the provision of performance in a giant that will benefit riders of all types. And looks great.
Good on ya, Yamaha
