Re: Was a little cold this morning so I clicked on the grip warmers for the first tim
Check eBay or Beemer Boneyard for a used grip heater, unless of course you just want brand new and can handle the sticker shock. If you need a new grip rubber you can replace both sides with part number 32 72 2 332 620. It is actually a grip for another model BMW but fits both sides of the K1200LT and is much cheaper than the K1200LT original part. Once installed you really won't see much of a difference and I have found that this grip rubber has lasted much longer than my original grips.
To install the new grip rubber you first remove the old by very carefully cutting off the old grip (sharp knife, great patience) starting from the end closest to the center of the bike, then peeling it away. You must not cut down into the heating element or damage the element while peeling away the old rubber which will be slightly stuck to the heating element.
Once the old rubber is off and the area is gently cleaned (time to install your replacement heating element and run the wire) you need to prepare the new grips. If you bought the part number I recommended you will first need to strip the rubber off of a plastic insert that comes with that particular part. Once stripped off, I applied a bit of contact adhesive to the inside of the grip then slid the grip into place, checked that the rubber was seated all the way down then let it sit and cure for 48 hours. I've tried using silicone/RTV but it eventually released and having a throttle grip spin in your hand while riding can be a bit of a problem.
The cheapest fix for replacing the grip rubber is to buy a set of Grip Puppies that slip over the existing rubber. This also increases the outer diameter of the grip which may feel better to you and adds a bit of extra cushioning.
