    Mine is a 2011. No surge, but a lot of torque. Sometimes, too much twist and it will feel like a surge! Are you sure this is not just you getting used to the throttle?

    I'd agree with Ed. When I first came to my 12R1200RT (from an 1978 R100/7) I struggled some with the high gear ratio starting out and the sensitive throttle. It gets better with practice. Don't spend much time at one speed though when "running in" your new engine. Read that owners manual section "running in"

    have a 12 . No surge from day one. I did stall it in the parking lot at the dealer twice before I was underway. Cold I have stalled the bike a couple times. No surge. Sensitive throttle far better than my oilhead.

    Now 3 months old, 6,000 miles and it still keeps running better. I don't think my bike needs a booster plug. It runs fine the way it is.

    Having also come to the 1200's from the 1100/1150 lineup I too noticed the sensitive throttle. The problem is made worse (how bad varies by bike and age) by the lean burn conditons off idle dictated by the pollution requirements.
    In very simple, non technical terms, what the Booster Plug does is "fool" the computer into thinking the outside tempurature is 20 degreees cooler than actual. This causes the computer to richen the air/fuel mixture by about 6%. The richer mixture eliminates the portion of the throttle sensitivity created by the stock lean condition.
    So, while the Booster Plug may not completely eliminate throttle sensitivity it does moderate the effect.
    Having said all that I would not install anything until your bike is broken in. As the bike breaks in the engine changes and the throttle response you have now is not what you may have in a few thousand miles.

    Give it some "time in the saddle." Engine mapping/throttle sensitivity takes several thousand miles to settle in - with the rider as well as the machine.

    The R1200RT is a sweet ride - will never have the low-speed throttle control manners of a V-twin, but still a nice bike.

    Good Luck and Ride Aware!

    Booster plug. Or, the Accelerator module.

    I use the latter on my '05 GS. It helps at low RPM. Might be different with a camhead.
