Interesting that's for sure

Change let's hope,no where to go but up!!

It makes sense. I was having a conversation a few days ago (and parts of it yesterday) about the MT-09. Coming in at the FZ6R price with more power than the FZ8, Yamaha is probably discontinuing both bikes, maybe the FZ1 too! What will fill up their line up?

BAM! Probably a bike to compete with the CBR500 / CB500F and Ninja 300. Gonna be sad to see our trio of bikes leave, but hopefully Yammi knows what they're doing. More and more people are buying smaller bikes, so I see this as a good move. Another reason they should be selling a 250cc version of the YZF-125r

It better be damn good line up..otherwise they will look like dummies trying to match other competitors 2 yrs too late.

 

[Marthy]

That look like a nice power plan. Hopeful it end up in a small/light package beginner bike. I find funny that everything is now cross plane... maybe they should use cross thread bolts too! LOL

Reading that makes no sense

the parallel-twin will not technically feature a crossplane crankshaft, but will be considered part of the family by Yamaha, presumably because, like the engine block featured in the FZ-09

If not a crossplane crankshaft, how is it "part of the family" and how does the triple cyl engine have to do with the twin being part of that family???
Next thing the Dirt bike lines w/ be in the "crossplane, w/o actually having crossplane, family"
Sounds like a bunch of mumbo jumbo..

Meh, someone attempted to write about something he seems like doesn't know that much...

Puts out decent power for a 2cyl motor. I'm just not a fan on the sound the 2cyl motors make.

From what I've read, the crossplane concept deals with uneven firing orders in order to increase traction. I don't know how it works, but I do know that a 120-degree crankshaft on a 4-stroke triple will give you 2 power-strokes during one revolution and 1 during the other.

Thanks for that.. I been looking since that post and I had simply thought "crossplane" referred to the piston configuration. I don't know engines, but basically the wide V shape of engine is what I thought it was.

I have to apologize because I did't give you a complete answer. The difference in the engine is in the crankshaft. Here's an explanation....

The triple won't need any crankshaft changes. If the twin is really going to be a crossplane, Yamaha will change the crank. If not, then they're using the term for marketing.

I think twins with a 270 degree crank sound and respond better than twins with a 180 degree crank. It's not really "crossplane" but it does mean both cylinders are not reversing direction at the same time. Yamaha already uses this configuration on the Super Tenere.

The interesting thing is that this one could easily be de-rated for use in places where there is graduated licensing, to compete with the Ninja 300s and Honda 500s, but also run full-power elsewhere. In all likelihood this is the future entry-level sportbike engine.

I suspect that the FZ8-FZ1 range will be filled with a couple of different variants using the new triple. Maybe faired and unfaired versions that are otherwise mostly similar. Maybe they also put an I-4 crossplane on a new FZ1, though I'm guessing that with some tweaks they could get enough out of that triple to remove the need for any I-4 engines in the FZ series or whatever replaces it.
