I ordered a set of Beemer Buddies just before a two thousand mile trip on my R1150RT. They worked very well. I have large hands and the original grips are small for my hand size. I found that I was able to maintain a looser grip that helped with hand fatigue. (I needed carpel tunnel surgery after my first trip on the RT). This was probably an ongoing issue long before the trip.

I ordered the set the week before the trip and I received them on the Saturday before leaving on Monday. I can't say enough for the product or the service I received. This made the trip much more comfortable. The installation was simple (even for me). I would recommend this product for those that have large hands. It certainly helped in my case.
I don't have any vested interest in this company. I just like their product.
