Yamaha Cross-plane Triple in ADV bike?

I read elsewhere that this engine will be used in several different models beginning in 2013. Could this power the 800cc class Tenere that some have been clamoring for? Seems like Yamaha could have an instant competitor to the Tiger 800XC and GS800 with this if they wanted to. Thoughts?

PS Apologies in advance if someone else has already mentioned this. I did do a search, however, and didn't see anything.

It looks like the R6 triple might be 675cc. Wasn't the motor in the Tiger 800 a derivative of the 675 triple used in Triumph's sportbikes?

It would be pretty ironic that the bikes initially produced by the reborn Triumph back in the 90s were built on the Japanese model, and now it's possible Yamaha could be following Triumph's playbook in certain sectors. Just speculation of course, but interesting nevertheless.

Like Triumph, I don't see any reason Yamaha would limit their triples to sportbikes only; as a matter of fact, using it in a broad range of models would lower costs further. I'm intrigued about where this will all lead.

A couple of quotes from the Visordown story:

Yamaha...said the triples would “shape Yamaha's future motorcycle line-up” but stopped shy of spelling out exactly which models the motor would appear in.

"Our sources say that several different three-cylinder engines are under development, in a range of sizes, to cater for the wholesale change in the firm's line up." (Underlining is mine).

"It's now becoming increasingly clear that triples could become the dominant layout in future Yamahas, covering everything from scooters – the firm both patented and tested a 750cc three-cylinder T-Max derivative several years ago – to superbikes."

Yamaha does have many years of experience with this layout, both in watercraft and snowmobiles, even more if you consider the 3-cyl. motorcycles they produced in the late 70s and early 80s, although those probably faded from even Yamaha's corporate memory to a certain extent.

Japanese made cross plane triple, what a concept!
I'm looking forward to a motor like this in a min 100 hp, max 500 lb chain drive KTM SMT type adventure bike.
And please include a 300 mile range to tank of gas.

i bet the Triumph execs are all smiles and thinking how they were right all along.
i see the big advantage is a narrower motor, yet still smooth like a 4 cyl.

Sounds to me they are looking at something other than the typical 120 degree crank throw, like a Triumph.

Seems like it. Those 120 Degree triples are so 1970's. YAMAHA moved on from those years ago.

So how does a company like YAMAHA do this seeing that they tend to be both conservative and clever at the same time Grasshopper?

They have been doing it for a long time. TDM's and the Tenere have twins with offset cranks. The 4 cylinder race bike have cross plane engines.


I suppose one reason is the one they gave, another given for the 4's was the pause between power strokes enhanced traction. Similar argument for vertical twins that act like V twins.

A lot of their inventiveness unfortunately, were not a sales success.

2 is not enough and 4 is too many

Four cylinder bikes can be buzzy at higher rpm's and more expensive to manufacture.
Large twins seem to have more emissions challenges and can lack high rpm zing. Large inline twins don't seem particularly smooth, and large V-twins are more difficult to manufacture and lack low center of gravity.

I was very impressed riding Triumph's 1050 triple and 3 cylinders just seems about right for that displacement. Their 1200 triple seems like it's packaged in a fat pig (except for the little gas tank). Their 800 triples seem a bit wimpy.

I've always favored the advantages of bikes that are made in Japan. Eventually I could see owning a Yamaha triple adventure bike. I hope they continue the idea they used in the Super Tenere of dry sump lubrication to keep the engine mass lower to the ground. I am really curious to see the end result of how they balance the thing, and of course what displacements are chosen.

If they build this could be the replacement for my S10. Older I am lighter I want my bike.

And hope they have an adventure version with strong rims (21"/18"), good suspensions and confortable seat.

Yeah, I vaguely remember those 750 & 850 triples, if I recall, they were not well received.

If they build this I am in! I'd hope that they'd go with spoked tubeless rims, I am not really into tubed tires on an adv bike. Make it really burly, right from the get go, like an Africa twin!

I just want a smaller tenere. I love my S10, but i want it to have a smaller version for a bit more off road. Plus having a 600/800 and the 1200 would be sweet!
