I bought this device and it's ala carte, dummy, left-side, mate for my K1200RS mostly because it was about about $40 cheaper than the Throttlemeister. The installation was straightforward, the directions were adequate, and the required Allen wrench was provided in the kit. This was the only tool required, unless you want to count a template for cutting the end of the hand grip. No template was provided.

The Wrist Rest worked fine for the 12 months that I used it. I removed it from the bike initially because I was replacing my worn out hand grips. However, in this process, I discovered some unpleasant characteristics of this device which made this a permanent removal.

While removing the left side dummy, or bar end weight, which is what it really is, I initially found it impossible to break loose the bolt which held the bar end in place. In fact, as I applied torque on the bolt, the entire assembly, with its in-bar receptacle, began rotating within the handlebar. I ultimately had to resort to an impact driver to get it to break free. When I backed out the bolt, I found that it was loaded with corrosion. This appeared to be due to the use of untreated dissimilar metals. The bolt and bar end is stainless steel, the in-bar receptacle is aluminum, and the handlebar itself is mild steel. Not good. The corrosion was heavily caked.

Now looking inside, I found the wires to the heated grips were now sheared, due to the rotation of the whole assembly which was caused by all of this corrosion. Bummer, as I was only planning to replace the grip rubber and not the heating elements themselves.

I next tried to remove the in-bar receptacle. This is held in place by a small, 2 or 3 mm set screw. I used the allen wrench which was originally provided in the kit, but found the little set screw hopelessly frozen in place, also badly corroded.

With no other apparent solution, I attached a pair of vice grips to the the protruding end of the receptacle for use as a strike point, and tapped the receptacle out from inside the handlebar. Of course, the ID (Inner Diameter - Ed.) of the handlebar was gouged by the receptacle's set screw which was still firmly locked in place and doing its job of resisting the removal effort. The handlebar's ID was first scored by the rotation of the assembly, and then again, during removal of the receptacle.

I contacted Bob's BMW and explained what was going on with the corrosion. My request for some kind of assistance or replacement parts was met with "Oh really? That's too bad. Never heard of that before." That's it. Bob's BMW made no offer to refund my purchase price, nor to even replace the damaged receptacle and bar end, and certainly not to replace the heated grip. There wasn't even any concern over a possible design problem, not even a "Doesn't sound right - I'll check with the old man". Nothing but apathy. In short, they refused to provide any assistance whatsoever. They did offer to cheerfully sell me the replacement parts, however.

This product gets a "Thumbs Down", and so does Bob's BMW for total lack of support for a product of their own exclusive design, and for expressing zero interest with the problem.

Humbly submitted,
