    I've liked the character of the Triumph triples I've had a chance to ride. I'm glad to see that someone else is getting in on it.

    The Hell For Leather headline says "Cross-plane Crank." How the heck do you make a cross plane triple? Really funny balance shafts?

    All of the 3 pointed star imagery in Yamaha's display seems to indicate the standard 120* crank, surely with the standard 240* firing intervals.

    I think Yamaha is just trying to build themselves some branding with this crossplane stuff, like when they promote the 270* crank in the tenere as crossplane, where they didn't use the same marketing strategy for the TDM/TRX.

    Of course, the point of the crossplane 4 cylinder in the R1 and M1 is to eliminate crank speed fluctuations due to inertial torque, and this is true for the 120* triple and the 270* parallel twin, so can't fault them overly much for trying to work it into their branding.

    I'm hoping it's a new R6, :deal

    If it is 800cc or less and on a standard or ST bike, I'm in.

    If they just plop it into yet another ADV bike, I'm out.

    I remember them. A friend had an 850 - it was the first street bike I ever drove. They were pretty dull compared to the Honda and Suzuki fours of the time. Yamaha eventually dropped them for the Seca 4 cylinder series. Hopefully, they'll be more competitive this time around.

    I recently drove a Tiger 800 for 1200 miles. I could love a triple! So smooth, so torquey!

    +1..... It's hard to imagine why a triple wouldn't have a 120° firing order. I'm also in for a new triple R6. Should be able to make it a little lighter as a triple, no?

    Laverda did a flat plane triple, iirc

    not saying it was good, just that they did it.

    Yamaha is just Jones-ing for a bit of Triumph Pie. :rofl

    I do love a triple... so I'll be watching.

    The initial 120 degree triple that Laverda developed shook like a paint mixer. So much so that it cracked its frame. The company then isolated the engine in a new frame with rubber mounting points and the rest is history. They sold such a bike as RGS and RGA models until the Breganze firm folded. Even with that revised frame, the bike can be really buzzy on the road if the engine isn't in a sharp state of tune.
    Frankly, I prefer the old Laverda triples with the 180 degree cranks. They are less likely to put my hands to sleep due to vibration.

    It sounds like there will be a lot of new stuff based around the triple engine concept.

    You would have a 120° crank in a two stroke triple. A four stroke would be 720°/3 = 240° for even firing.

    Test rode a '78 XS750 once, man those are sweet bikes! I loved the triple's power delivery, it really does straddle the middle of a parallel twin's punchy character and an inline 4's smoothness.

    The XS750 is a lovely sounding bike, has an amazing growl. :D

    My first ride was a Yamaha XS750 triple, wasn't fast or particularly dependable for me, but riding it put a shit-eating grin on my face every time. Made a sound like a nice, hoarse, raspberry blat.

    Anything less than a liter should be a triple or a v twin. Unless you want a race motor, the 4 cylinder is just to big. A nice 3 or 2 cylinder engine makes the bike so much more narrow. If the FZ8 was a triple or a V-twin I would have considered one, but another 4 cylinder, meh...

    Hell, even small displacement cars run 3 cylinders instead of fours.



    No parallel twins though :puke1

    I would guess that maybe they will build a smaller touring bike with something in the 700-900cc range, a more budget bike than the FJR with less options but making a good entry level lighter weight touring type bike.
