Title: Replacing grip rubber on heated bars
Post by: MadMountainbike on November 01, 2018, 06:41:45 pm
Anyone out there had a crack at replacing the grips on heated bars? The OEM instructions for the replacements seem straight forward.

You carefully cut off the old rubber making sure you don't cut in to the heating element, remove the old grip, clean with isopropyl and then slide the new grip on... sounds simple but I'm sure it won't be! 😆

Just wondered if any of the clan had done this and had any tips?

Seems straightforward as you say. Just go for it... ;D

Assuming you have an unused tube of KY jelly laying around, it's great for helping to get new grips onto the bars  ...  amongst  ...  er  ...  other things.

I've always used a little soapy water...to the refrain of 'I'm forever blowing bubbles'  ;D

No need to use KY or washing up liquid. Just use an airline. Take a look here.

 Much easier to replace the whole grip - they are not designed to be messed around with like this, so high chance of breaking it as you go. Used ones on fleabay aren’t expensive (£30 or so), and you can always send it back if it doesn’t work.

The instructions and the grips I've got come from BMW. There's nothing wrong with the heating, it's the grip rubbers that have aged and become worn and slippy (they're what... 12 years old now), so that's the bit I'm interested in swapping. The bike isn't high mileage, just getting on a bit like me 😊

I slide these ( with the help of some washing up liquid ) over the existing grips.

Gives you a bit larger diameter to grip & helps eliminate vibration.

The heat from the grips does come through but may take a bit longer.

Grip-Puppies for me, heat still gets through.

Agreed, mine have been comfortable and give plenty of grip.

Grip Puppies are expensive and cheaper bits are available but the ones on my K12S did 20'odd thousand miles and never even looked worn in, let alone worn out. Much more comfortable on my tender little hands than the 'orrible standard grips.

The standard grips on my R1150GS were much more comfortable and were barrel shaped, fatter in the middle and narrower at each end and very 'cushiony' feeling.

The big advantage, for me, of the Grip Puppies is the slightly 'slower' throttle action for a given wrist movement.

I also use grip puppies. I do have big hands, feet, and - you've guessed - big shoes.

I've done it, its not a big job. you have to be careful when cutting off and cleaning the silicone glue, that you dont cut the heater wires in their grooves.
I wouldnt use soap to put them back on, but silicone RTV, this way they will be in full contact with the heaters and not slip around or get slack.
I bought grip rubbers from wunderlich, and as a bonus changed to the contoured ones which i find more comfortable

Hello guys, on the way back from the bike show i tried the heated grips, and guess what ? Only the left one worked. I've looked round the forum and it appears the switch gear has problems.
What I wondered was how the current got to the throttle grip, is there a slip ring or is it hard wired given that the grip rotates.
The bike is a 2014 model, I haven't used them in the last year and from the bikes mileage and condition, I wouldn't have thought they had been used much at all.

Any info greatly appreciated.

Best regards.   Mick

I suspect that will be replacement switchgear on the right that you'll need.
If you have the BMW warranty, its covered, but will cost the £100 excess, of course.

As an aside, my righthand switchgear also got replaced for my hot start warranty claim, because the extra battery loom fix didn't do the trick.
It's the one warranty thing that I have claimed on - for both bikes.
(Which means I'm not getting good value for the warranty, but I like the security. Odd, really.)

If one grip is still working I would suspect it is either a wiring fault or the grip itself that is faulty.

Although i've had the grips off my bike when changing the yoke, I can't remember how they were connected.

I can't see BMW adopting an expensive slip ring system when they can get away with extra flexible wire.

That's what I was thinking, I dug out the reprom and had a look but it's pretty vague, it didn't show a slip ring. I'll meter it out in the week,the left one worked fine on both settings.

Best regards. Mick

You're of  for an ew grip . Nothing to do with the switch.

I'm told that it is normally the left grip that packs up. When pushing the bike about the twisting on the left grip which is fixed damages the grip whereas the right grip twists.

Another BMW first. Everyone else manages to get them to work OK and I never heard of either packing up on the old GS when I had mine.

I've heard this before and is, I believe, common to all heated grips that are wired via a "fixed" connection with the handlebars. No a BMW specific issue and definitely not a K1?00S/GT/R issue.

I haven't had chance to look at it yet, but I did phone the stealers. If it's the grip, it's £111. And if it's the switch £132.
I had a bit of a moan at the guy about it being a common fault and that the bike has low mileage and probably never been ridden in the winter, he said they'd replaced a few, switchgear that is,  but all under warranty the last being a 2016 1600.
I've had four Fireblades since 1993 and never had a mechanical failure, and only one re-call.
I love everything about this bike but this failure should never happen given that BMW have been fitting heated grips to their bikes for a long time. I have a 10 year old Jeep and the heated seats are used every day in the winter and still work perfectly.


Best regards.  Mick

Dont get me going on heated Grips  :-X
See you've done it now. My 14 plate bikes Heated grips were excellent and had to sometime turn down to setting 1 as very toasty. New 16 Motorsport and grips almost worse than useless. Bck and forth to dealer but told within the 8 degree spec and as we all know that can make one massive difference at temps up here in the old North east. Nothing they can do, even though you can apparently go online with GS thingy and turn up output. Although nobody can explain exactly what is required here and what output to look for.
Amazing the dealer cannot do this if possible?? As i will be keeping this bike until im seventy or cant physically move about i would travel to location if anybody can definitely carry this procedure out??

The members map shows members with GS 911s that are willing to help. The red map pins are members with GS 911s.
A link to the members map can be found in the Who's Who section.

Cheers for that.
Nearest me is down in Edinburgh about 3 half hours. However be worth a visit.
The only thing i would need is some sort of procedure explaining what output setting is required to be changed and a min / max range.
Anybody any ideas, think Costas did mention you can change but no procedure as such.

I can categorically tell you that they did pack up on the GS. My 1150 GS went through three sets of switch gear and heated grips under warranty before they stayed fixed. In fairness appart from that and some paint finish... and some replacement wheels... and a new clutch because there was an oil leak via the bell housing... all fixed under warranty in the early days, it settled down and I did just shy of 130,000 miles on it and still sold if for a couple of grand, so it wasn't a bad old beast.
