    How to detune and limit

    Hello I am new to the Honda Groms and have an odd question.

    I bought a 2015 grom for my daughters, in Oklahoma children are allowed to get motorcycle license at 14.

    I would like to detune it and limit the top RPM until they get comfortable with it. Is it possible to restrict the rpm or throttle stops with an ECU flash or other means?

    This is a first bike for my daughters and want them to not have to worry about it unintentionally taking off on them while I am teaching them clutch and gears...

    @jonesn may be able to help? He can raise rev limit, so don't see why he couldn't lower...

    just adjust the throttle cable length so that it will not go full throttle.

    The real best bet is to have a teenager go to a motorcycle driving school or even a motorcycle off road school to learn how to use the throttle and brakes. To me the best motorcycles riders I met came from off road mc racing circuit.

    A child can get a motorcycle license at 14 in Oklahoma?

    I think you'd be much better off buying a used Honda CRF50 or Honda or Kawasaki 110 to teach them, but that's my opinion.

    I think the Grom is a good choice for this.

    My daughter wants to drag race. and if I know her she will be running wide open on my 14r as soon as I let her. I want her to learn to crawl before she tries to fly.

    Actually the Grom is a good choice. Both bikes you are posting are strictly for off road use. It is not legal to ride on the street with bikes that do not have at least a head light and tail/brake light. Not sure about signals.

    Most mopeds in the 80's had between 3 to 5 horsepower, scooters and groms are about 8 to 10 horsepower. Between its size, HP rating and that it has all lights and is 100% street legal. It is perfect for a 14 year old 130 lbs girl to learn on. Scooters are fine if you like high dollar mopeds that don't require you to learn to shift and clutch. But she needs a real bike that builds the full skill-set for riding a motorcycle.

    It's better to learn on dirt. Nobody will convince me otherwise.

    Outside of that, how is it legal for her to ride on the street?

    In California, it was 15 iirc, maybe 15 1/2...

    Looks like you need to be accompanied initially at least in OK.
