Yamaha have unveiled the new 2009 R1 in Las Vegas today.

2009 Yamaha  R1

The Grand Ballroom in the Mirage Hotel in Las Vegas  was the venue earlier today when Yamaha unveiled the all new R1, along with other 2009 models at the annual Yamaha dealer show.

Even with its heavily revised appearance,  the most notable feature of the 2009 R1 will be something you can’t see, the crankshaft. Although you can’t see it, you will certainly hear it. In a first for inline 4s, Yamaha have given the bike an M1 style cross plane crank, meaning the cylinders fire unevenly, for a smoother power delivery. It also gives the bike the distinctive “big bang” sound of the M1 MotoGP machine, a distinctive mix of twin and four cylinder exhaust note.

The R1 still features the electronic throttle (YCC-T) and the variable length intake trumpets (YCC-I). It also sports a 3 position drive mode, with a “Normal”, “A” and “B” setting, presumably representing All, Most, and Some of the R1’s as yet unreleased  power figure.

“SOQI” forks are MotoGP inspired, with damping in the left leg, and rebound handled by the right. Rear shock features a new linkage, and Yamaha have now added an electronic steering damper.

The frame is all new, with a magnesium subframe.Small projector headlights allow air intake in the space previously occupied by the headlights.

Footrests are adjustable, for height and position. The R1 will be available in the US at least, in four colours, white/red, blue, black, and yellow. USA deliveries will be commencing in January 2009. No word yet on Australian colours or delivery timeframe.
