Since my recent heated grip incident and since this seems to occur MUCH more frequenly on K1100s and virtually never on K75s/K100s, someone has sugested there may have been a bad batch of heated grip wiring used at the factory. In the interest of seeing if that might be true, the purpose of this poll is to see collect some data to if there is any pattern to this problem.

Please only vote in this poll if the heated grip wiring under your tank has melted/burned up. If your heated grips just stopped working on one side or went out for some other or unknown reason then it could be another cause so please don't vote in that situation.

If this ever happened to a K75 or K100 you owned, please check the K75/K100 option and provide the year and model in your post.

(I'm going to make this a sticky and leave it up for a while to see if I can gather enough data to detect a pattern.)

Drake, my left burnt due to me standing alongside the bike and absentmindedly turning the grip. Dooh!

Please add to the poll. "my bike didn't have them as standard" & "my 95 LT never failed". As my 91 didn't, my 95 did & my 97 highline doesn't.
hope this helps the poll.

But '93 LT, not '93 RS?

Now from the K11OG spec page (if I am interpreting the #s correctly?) for the year 1993 there were 993 LTs produced vs. 534 RSs- so there is more chance for the LT model to fail since there were more LTs made.

But no RS failures? Probably just a lack of RS owners reporting such.

I obviously did not add my "RS" vote because I have not experienced a failure (yet?) but I do experience an occasional but erratically scheduled blown grip heater circuit fuse (2 in 2007, 3 in 2008, 1 last year- and I rode with the heaters on more last year).

did the 93rs even have heated grips as an option? mine has nearly every option available that year (maybe every?) and i don't have them. the stock wiring on something that isn't stock can't fail ...

If you ask me, (which BMW never has Rolling Eyes ) it's not a great design. The low setting runs the current through a resistive wire to reduce the voltage to the grips. The only way for that to dissipate that power is through heat - which ends up melting insulation and causing shorts.

The Symtec design, with separate hi and low heating elements in the grip is better and more or less immune to causing shorts like the OEM stuff can and does.

On my 93K11LT the left grip stopped working. When I pulled the tank it was the plug that melted. I replaced the plug with one from an old harness and it started working again. Then it stopped again and I looked and the replacement plug was melted and this time took a few other wires with it. I fixed the damaged wires and now my bike does not have heated grips. I left them umpluged under the tank.

Both the K-RS I've owned- the first (a '94) for a week or so until the dealer bought it back and my current ride (a '93) both had BMW grip heaters with the BMW dashpad switch. I didn't know that it wasn't available on an RS

BTW, you can avoid this happening by never using the heated grips on the low setting. That's the circuit that has the resistive wire that heats up and melts things. If you want to make 100% sure it doesn't happen then cut the orange wire in the heated grips wiring.

Good info on keeping the heaters on high. I never thought of it and tended to keeping them on low to prevent overheating. Thanks.
Just as a matter of information my '94LT with 78k miles and my '95LT with 11k miles both had fully functional grip heaters.

I haven't looked into how my C650GT's seat and grip heaters work. I should take a look at the circuit before the warranty runs out.
