Yamaha Shows New Three-Cylinder New prototype Triple from

Yamaha is waking up. At last Intermot Motorcycle Show in Germany, the Japanese bike demonstrated modern “teaser with an enigmatic display of a new engine between two wheels and a fork, with our imagination of the symbolized by a filigree of wires and The display platform took the of an arrow, and the short text was “Where to Next?”

This has a storm of speculation, mainly of the inclusion of the words “crossplane This refers to the MotoGP-winning developed by (now retired) 
engineer Masao Furusawa overcame the natural rpm “flutter” of caused by their pistons all 
simultaneously every 180 degrees. the crankpins out of the normal single to be in two “crossed planes” at 90 degrees put the pistons near their speed while the other were stopped.

That eliminated the flutter and disturbance formerly caused by and stopping all the pistons together per revolution. Rider Valentino then used the resulting YZR-M1 to win four MotoGP

An inline-Triple is naturally “crossplane,” its three crankpins in three planes, spaced at 120 degrees to other. With this there is zero shaking of the center of mass and zero rpm flutter caused by piston torque. But there is a side-to-side

In modern engines, this couple” is canceled by a crank-speed shaft.

In the photos from I see a housing in front of the new Triple’s That is the natural place for a shaft. I also see three exhaust header pipes into one under the engine, an even firing order.

The engine is very short to back, as all modern bike are, and utilizes a vertically gearbox to achieve this, mass forward and enabling use of a swingarm.

Have you listened to a lately? While the regular of a 360-degree Twin sounds a Triple has a mysterious, pleasing quality.

This is not Yamaha’s first with a Triple, as the snowmobile most recently used parts from an FJ1300 to 973cc and 1049cc four-… Also, its RX-1 is powered by a four-cylinder) version of the R1 motorcycle

Why the mix-’n’-match? It just makes to use what’s already in production in as ways as possible. Plus, we Yamaha was hit hard by the 2008 Lower parts counts are as are reduced bulk and weight.

Result? Fewer cylinders fewer bearings, and total of oil film being sheared reduced friction loss. engines cut costs.

What we know is Yamaha’s 
intentions. this “P3” engine the basis of lighter, more sportbikes? Might it power a of new products?

Yamaha says that it’s intended for a bike, that it is “a new direction” and there is a “new electronic system.” Keeping market in hard times means buyers interested. That’s what Yamaha is doing P3.
