09 Yzf-r1

From a press release issued by Yamaha Motor Corp. U.S.A.:

The 2009 Yamaha YZF-R1.

Cypress, Calif. – Forget everything you ever knew about the supersport liter class. Because once you hear the growl of the all-new 2009 YZF-R1, it will become clear that this bike is unlike anything before.

It’s all about power – delivery of power, to be exact. That’s because the all-new R1 is the world’s first production motorcycle with a crossplane crankshaft. Originally pioneered in MotoGP racing with the M1, crossplane technology puts each crank pin 90 degrees from the next, with an uneven firing interval of 270-180-90-180 degrees. The result is incredibly smooth, roll-on power delivery with outrageous amounts of torque for a rush like you’ve never experienced before.

The unique shape of the crossplane crank smoothes out fluctuations in inertial crankshaft torque to provide very linear power delivery as the engine’s combustion torque builds, giving the rider more linear throttle response with awesome power and traction exiting corners. Not just new, the R1’s new crossplane crank engine represents a complete paradigm shift.

To make the crossplane crank viable an advanced ECU individually maps each cylinder’s ignition and fuel injection timing. This powerful electronics package also controls Yamaha Chip Control Intake and Chip Control Throttle (YCC-I, YCC-T).

Also new for 2009 is the inclusion of D-MODE variable throttle control function that enables the rider to adjust performance characteristics to match a variety of riding conditions. In addition to standard mode mapped for optimum performance, the rider can select from A mode for sportier response in low to mid-speed range, and B mode for somewhat less sharp response for riding situations that require especially sensitive throttle operation. These 3 different maps at the push of a button allow the rider to choose the optimum power character for their riding situation.

This revolutionary new engine is housed in an equally advanced chassis. Control filled die-cast frame rails balance high vertical rigidity with relatively low lateral rigidity for increased high speed stability while improving handling, especially while leaned over during corner exit. A control filled die-cast magnesium sub frame cuts weight far from the center of balance and contributes to concentration of mass.

Visually the new R1 breaks new ground leading with twin projector beam headlights concentrated near newly placed forced air intake ducts. The sculpted body work features inner and outer shells controlling airflow around the bike at high speeds and forcing more cool air to the radiator and engine bay while eliminating the need for hot-air vents usually located at the sides of the radiator.

More than the just the next-generation of supersport; the 2009 YZF-R1 represents a major breakthrough in supersport technology and performance.

The new R1 will be available in dealerships nationwide beginning in January 2009 with a starting MSRP of $12,390. The 2009 R1 will be available in Raven/Candy Red, Pearl White/Rapid Red, Cadmium Yellow/Raven and Team Yamaha Blue/White.

2009 Yamaha YZF-R1 released!

After providing as much speculation, information and product renderings to readers as possible, we can finally spill the beans on the much anticipated R1. Yamaha has pulled out all the stops with a ground-up re-do of its iconic literbike. New bits abound, including its styling, chassis and, most intriguingly, a MotoGP-derived firing order of its innovative engine.

In the top class of roadracing, engineers have battled with harnessing the huge amounts of power and getting it to the ground efficiently. In 2004, Yamaha's GP engineers introduced an uneven firing interval for its inline four-cylinder M1 with what's called a cross-plane crankshaft. Instead of the two outer and two inner pistons rising and falling together, the R1's engine has individual cylinders firing 90 degrees apart from each other. This eliminates the torque fluctuation of a typical four-cylinder mill, plus it gives the Yamamotor a very distinctive exhaust note similar to that of Valentino Rossi's racebike.

"It gives a much more precise feeling in the throttle action," says Yamaha's product planner Derek Brooks. "You fill like you can sense that edge of traction."

Once again Yamaha will prevail in style and performance as always. The 2007/2008 models obviously had the engine heat issues and the well known 2nd gear glitch which resulted in some ECU recalls. It looks like the Yamaha crew took notice of that and decided to out-do the competetion this coming year! The new styling and color options are sexy as hell! I might have to sell my 2007 and get this one!!! KUDOS to Yamaha!
