We must be getting close to the 2013 World Superbike season-opener at Phillip Island, because a bevy of teams are…
Reading through the comments on the Attack Kawasaki CRT bike and its new crossplane crank, it is clear that the concept of what makes an engine have a crossplane configuration, like the one found in the current Yamaha YZF-R1, is still a bit of an enigma for some motorcyclists. Referring to the way a crankshaft is built, with the four crank pinks at 90° from each other, an inline-four engine with a crossplane configuration fires its four pistons in a different order, and with different intervals between ignitions, than a normal engine with 180° pin positions. A subject we’ll broach in greater detail at a later time, we thought this video from Yamaha would at least highlight some of the major differences and reasons for using a crossplane crank in a sport bike motor. Enjoy it after the jump.

Down from the 23 bikes on the grid at Phillip Island in 2012, the euro-centric series is still dealing with the economic downturn in Europe, which continues to linger in the important markets of Spain and Italy. However though, it is of note that the difference in machines can be attributed to the absence of the Liberty Racing Team, which ran four riders in the early part of the 2012, before falling to pieces by the conclusion of the season.
You can tell it is the off-season when the subject of what Valentino Rossi’s Yamaha YZR-M1 will look like is an instant buzzworthy item, and you know MotoGP fans have been pretty hard-up over the past few months when even the test livery creates a frothing at the mouth. Today is no different. Allegedly tweeted by the bike itself, Valentino Rossi’s test livery for MotoGP’s first pre-season test at Sepang is already creating quite a stir on Twitter. There isn’t all that much different about the Sepang livery and the livery on the Yamaha M1 that Rossi tested last November in Valencia, except of course for the fact that Monster Energy has been added to the layout.
