One thing I noticed are that the grips are fairly "skinny" and that for my hand size I would like them slightly thicker. Now, that was definitely something I didn't want to spent a lot of money on so I searched a bit and found the "Grip Puppies". Hmmm. Ten bucks? Worth a try ...
So I ordered a pair and installed them and finally got around taking some photos:
In the photos they look brighter than what they actually look like in reality. They seem to reflect the flash more than the other black parts. They are actually fairly unobtrusive.
Fitting them was simple: remove the side holding screw from the bar end weights / hand protectors, moisten the inside of the grip with slightly soapy water, slide them on, replace the screw again, wait for it dry. Go. Easy and fast.
So, how do they work?
I would have preferred if they were slightly thinner. They add about 0.8cm to 1.0cm to the grip's diameter and I still have to get used to this. I like it though, they are not too thick, just feels so different after riding with standard BMW grips for about 9000 miles (combined on the F800GS and the R1200GS). Another good thing is that they dampen vibrations slightly and make the grips softer.
Overall: well worth the money and most probably the best value I've spend on a bike ever.
