Yamaha 2013 MotoGP Launch - Bike Photos And Specs

The Yamaha Factory Racing MotoGP team launched their 2013 campaign today, and unveiled the livery they will be defending this year. Below are the official photos of the bike, and the (highly vague) specs as provided by Yamaha. Yamaha have also provided a page with downloadable wallpapers of the bikes with and without Valentino Rossi and Jorge Lorenzo:

I was holding out just a little bit of hope that the bike would keep the testing color scheme. Ah, well. Not the first time I've thought the season livery wasn't as cool as the pre-season aesthetics ... Still nice-looking bikes, though.

Livery/looks can play a big role in marketability , so why more dull(ish) corporate colours.? Some guy has done a couple of mock ups that I've seen on twowheelblogs. The black and white monster m1 is fantastic. Yamaha take heed.. Will never match the global image of the repsol honda without a bit more umph...

Honda 1 Yamaha 0 on the livery scoreboard. It doesn't count towards the WC though.....

Too bad that those tech specs do not reveal anything. These are simply the things you can see or are regulated and are almost universal for all the bikes, with the exception of the crossplane crankshaft. But that is already standard in the Yamaha road bike as well.
Also, 240 horsepower seems a very conservative number to me, given that a completely standard 1000cc road bike (at least the BMW S1000RR) nowadays is already producing 200 hp at a considerably lower rpm level.
By the way, you could add bore x stroke dimensions in the above list, since bore is restricted to a maximum of 81 mm, so all real MotoGP engines will measure 81 x 48,5 mm, which is just a tad more oversquare than a BMW S1000RR (80 x 49,7 mm).

Apart from all that, I think the colour scheme is a bit bland for a GP bike. The Yamaha looked so much better in the classic red and white racing colours that they used in 2011 a few times.
