    2015 deluxe. I am learning this bike and have searched but have found no answer. Is first gear rpm limited under 7-8 k rpms. Seems like the bike bucks/ pukes around there. Almost like valve float.

    Are you letting get up to temperature? Should be at about 142 before V-tec will work. If not warmed up it will cough and sputter till it gets somewhat warm, I don’t know exact temp, but I always wait till it get over 120 before starting out.

    First gear is not limited, I gotten frisky and wound it out to over 10K no problem.

    There’s definitely not a rev limiter on the RC79 below the redline, I’ve taken my to the line a few times and no problems ...but always after a few minutes riding, I also warm it up until the revs start to drop before setting off

    I’m inclined to agree with Allyance that the motor is not hot enough

    6,700 is where the VTEC cuts in, should be smooth by 7,000

    Only when the engine is cold, the vtec doesn't kick in or something like that. Once up to temp it will be fine. As your initial statement provided no info bar revs I took it as from initial start up.

    Wasn't up to temp. Did some riding today and verified that I wasn't up to Temp. All is well when it is warm. Thanks again

    I experience some hesitation early in the RPM range from a cold start and immediate take off. I learned to just let the machine warm up a bit. I will wait until there's a temperature read out on the display before starting out and that helps out a lot.

    I bought a new 2014 several weeks ago and noticed this. I've never owned a fuel-injected motorcycle - let alone one with VTEC. The first time it happened, I thought there was something wrong with it, but it's comforting to know it seems normal/typical for this model. Runs great after just a few minutes of warm-up, but it can be contrary until then.

    Why are you all thrashing on a cold engine?? That has the potential for so much damage!
    Even if the coolant is registering as somewhat warm, it takes a good amount of time to heat-soak the engine and get the internals up to proper operating temperature.
    Where do you have to be in a hurry that your WOT on a cold bike? Even if you are legit in a hurry and HAVE to start riding right away, take it easy for the first 5-10 minutes!
