    1992 r100r heated grips

    Hey
    Just got this bike and just joined the moa
    Doing my best to get some info on this bike
    Iím not sure if it has heated grips
    There are some rocker switches just above the ignition switch with no labels
    Only one appears to have any wires connected to it
    I tried switching it but no heat to the grips
    Bad fuse maybe
    No heated grips maybe
    Getting to know
    Thanks for any help

    Welcome aboard! I don't know about the '90's era bikes, but the heated grips on my '84 are switched by a rectangular push button tucked up near the headlight. The wiring runs inside the handle bar. I'd suggest looking at one of the parts fiches (MAX BMW, etc.) to see if you can figure it out. I'm sure someone more knowledgeable will chime in shortly. Pictures of your set-up would help.

    There is no separate fuse in the factory kit. More likely failed heating elements.



    Plus, I thought the factory rockers were below, rather than above the switch. Do you have a picture of the setup?

    On my bike

    I had heated grips on my bike from the factory. They lasted a long time then wore out. When I went to replace the grips, they were NLA from BMW. So, I put on a set of non heated grips and rode the bike. I was lazy and never removed the switch or wiring harness for them.

    One day I find the heated grips are available again and I install a set using the existing harness and switch.

    It is possible the previous owner did the same thing I did.

    If the existing grips are heated on your bike, at the center of the handle bars you should see the wires for them. No wires no heated grips.

    If there are wires, the grips could be bad or a wire could be off/broken.

    I do believe the grips are still available as a BMW part from Max or another dealer. St.

    Well the rocker switches are definitely BELOW the ignition switch. Those are OEM looking switches. If an option is not installed, there is a wireless placeholder cover. A stock heated grip switch would have three wires coming out of it. There is no fuse. It could still have aftermarket grips with the factory switch or could have no heated grips. Sometimes when the OEM grips failed, people replaced them with cheaper aftermarket grips and used the same switch. Sometimes when heated grips fail, people abandoned them for regular grips. OEM grips are wired inside the handlebar. Aftermarket grips are wired external to the handlebar. To know which, if any, grips are installed, you need to look for wires coming out from the inside of the handlebar.

    If they are OEM, installed, and not working, you may end up back where I started looking for the reason your OEM grips do not work.

    When I added HG to my R100R I ended up with a separate switch. Not sure why; may have been something to do with bar end weights and which BMW kits were cost effective at the time.

    thanks for the input
    i will try and locate any wires running through the bars
    i got so many other things to do
    the bike has been sitting for quite awhile
    i just got the oil filter and all the extra bits to deal with an oil change
    going to drop the trans oil and rear end as well
    it needs a set of tires and i was hoping for something gs like for rougher roads
    any suggestions?
    also if any body has the same bike, i would love to talk
    i have been riding a /2 and a /5 for many years and this 27 year old bike seem so modern to me
    thanks

    My 1994 R100RT has a different dash but the switches appear to be the same. On mine the left rocker switch is for the heaters & has 3 positions: up is high, center is off and down is low. Mine have always worked fine, so haven't bothered tracing the wires but note that it takes a few minutes for the grips to warm up. Be sure you give them a few minutes on high to know if they are working or not.

    You will have lots of choices for a rear tire, but the 110/80-18 size on the front will be difficult to locate in adventure spec.

    It looks like Pirelli offers one in its MT60: https://www.amazon.com/Pirelli-24025...omotive&sr=1-2

    I ran an MT60 in size 120/70-17 on a Honda and barely got 4,000 miles from it. I don't know if that is typical or not.

    The grips on the '92 PD stopped working about 5 years back.
    A local wrench that specializes on Airheads and older Ks suggested to work the switch back and forth a few times.
    I had not touched the switch for several years so followed the advice and the grips heated up like they're supposed to.

    The switch on the PDs dash is below & to the left of the speedometer.
    It gets a little workout a few times a year now.
    Anybody that thinks heated grips aren't worth it hasn't experienced the magic that happens when it's cold and they're switched on!
