    NC700x Vibration at 4000 rpm 'ish

    Does anyone else experience an engine vibration at 4000 rpm, when in top gear it is around 70 to 75 mph.

    Yep, I do. For me it's between 71.5 to 75. Let's me know how fast I am going with out looking at the speedo.

    There's some vibration at any speed or RPM because of the crank design.
    Not my favorite feature by far.
    I'd much prefer it to run smooth as a sewing machine.

    I would describe it as more of a roughness than a vibration. Obviously this is also why a second balance shaft is incorporated into the 750. I find that it is most pronounced under heavy load but if the throttle is backed off a little under steady cruising it is not so noticeable.

    Somewhere, a while back in this forum, there was a discussion about the NC's engine characteristics, and IIRC, the gist of it was that Honda purposely used a 270 degree offset crank to give the otherwise silky smooth engine, a more aggressive feel, like a larger displacement vee twin.
    The 270 crank also allows much lower rpm shifting by lowering the torque curve to a useable level even at 2000 rpm.
    This is how we manage to get almost 60-70 mpg while at lower rpm than most bikes.
    Regards

    I was one of my "gripes" when I first got the NC. I like it now. There's nothing wrong with it.
    My Tenere (twice the engine) also has the 270 degree firing engine. Strangely, it is very smooth at 4K rpm's but has a good rumble/lope at idle.

    I have a 2015 NC750X, even though it has the second balance shaft, I still feel the vibration around 3000- 4000 rpm, if you turn the throttle. If you are cruising at constant speed there is no vibration.

    I just found this post but yes, I feel a slight vibration at 4000RPM on the dot regardless which gear I am in. Doesn't really bother me now. I feel like it's the sweet spot to change gear anyways.

    It's weird to read this. I have the 750XD and can feel the power strokes from starting at 1100 under acceleration up to around 4,000 then it smooths out completely. Under a hard load you might feel it a little bit more. Comfort zone, 70-75 mph.

    The bikes power curve and smooth zone remind me of my long gone R100RT. The faster you go the smoother it gets. I like that.
