    ASC, on or off?

    Greetings scooter heads! Since I am going on year 2 with my 2016 C650GT, I was wondering if any of you ride your bike with the ASC off. If you do ride with the ASC off, any noticeable differences in handling?

    Thanks in advance,

    Lee

    Never switch it off ... It has saved my butt many times on loose sand/gravel and wet/slick hard turns.

    I switch mine off every time I ride. The traction control is way too intrusive and doesn't allow a millimeter of slippage. It can be dangerous. Making a 90 degree turn from a stop over light street gravel the traction control cuts off all of the power. I had to jab down my leg very hard to prevent the bike from falling because of the loss of power. I wasn't anywhere near spinning out on the gravel and was applying light throttle. When I switched off the traction control and try the turn again, there's no drama even with more throttle. The traction control cuts off the power if you ride over a very small stone in a straight line, it comes on if you ride over a freaking pothole in straight line.

    And when I do have the traction control on, I always remember that normal throttle applications around tight 90 degree bends can cause the thing to lose power. Enough so for you to have to save the bike by jabbing down one of your legs. Take that same turn, at the same throttle without traction control and you will be fine, no spinning out or anything. The traction control caused the situation to be dangerous. I wish that I can permanently disable it. I do a much better job with my wrist.

    How do you do that?

    Please explain how you turn off your ASC on the C650GT. What am I missing here? There are times when I like to not concern myself with this feature and it does indeed cause freaky cutout if not ready for the cutout.

    When you go into the “Setup Menu,” there is an option to turn off or on the ASC.

    OMG ... Well, fortunately I have never had this issue with my 2016 GT at all, so I can't relate and I'm a very aggressive rider (sport bike rider). In fact I've always been impressed with how effective the system works for me. I can always tell when it activates and I'm always grateful (pot holes/stones/straight-line do not initiate it ever) ... Makes me wonder if possibly you have something else going on.

    I would bring it back to the dealer but I already know how it will go. So I'm not going to waste my time. Something is up because even with the traction control completely off the rear wheel will not spin for a complete revolution. It stops and and starts (tried it on wet grass). I"ll just live with it for now.

    Thanks

    Oh No ... Just know, that's not normal, typical, or a designed function ... that is a serious malfunction. I think you r experiencing a speed sensor failure ... So sorry you r having to deal with that

    I've got a '13 GT which does not have traction control. However, I experienced a power "shut down" spinning the rear tire in gravel. I remembered this thread from a while ago.

    There's nothing like looking when you're trying to find something.
