Default Yamaha Crossplane Triple

http://blog.motorcycle.com/2012/10/0...riple-concept/

Triple market might be getting a little bigger.

If they make a streetbike with a crossplane triple than sounds like the R1 crossplane...(commence boner)

Imagine parking a daytona next to that and listening to the difference? I am...(commence drooling)

Crossplane is the biggest thing to happen to the internal combustion engine in a long time. I'd really like to see it make it's way into the automotive market, too.

I'm curious as to how a triple wouldn't be horribly unbalanced with a crossplane, and I doubt the pros, ie smoother torque delivery, would overcome the cons, ie vibrations, lack of power, price, when the normal triple architecture already offers smooth torque.

Interesting concept. I've ridden an '07 R1 but have always been curious about the crossplane.

The exhibit displayed in the article is beautifully displayed btw

The real question is this:

A crossplane I-4 takes the cylinder's from pairs at 180 degrees of seperation on the crank, to individuals at 90 degrees of seperation.

Is the triple also going to be at 90 degrees of seperation, or will it be at 120 degrees, so that the combustion cycle is still evenly distributed (the whole point of being crossplane)?

It's about frickn time. I would buy one of these in a heartbeat; a triple with Yamaha build quality and easy parts availability. Sounds like a winner to me.

I don't quite get it.

The crossplane idea on the R1 was all about building better torque/power delivery characteristics into an IL4 package.

Triples already have most of those characteristics - I.E, better spread of torque and less tendency to spin up the rear.

I have to say it smells lie marketing to me. 'Yamaha introduces the crossplane firing order that powers the MotoGP leading M1 and the SBK R1 in a new, middleweight triple package.'
