Works very well. I like that this product is small enough that you can still operate the throttle without using the throttle boss. Similar products like the cramp buster are so large its difficult to operate the throttle without bumping the large paddle.
The boss works great. I installed it with very little effort and adjustment was easy. It really helps when traveling longer rides and integrates well. It looks like it would get in the way but it doesn't. Very much recommend it.
Kuryakyn makes great products. But you also have to make sure you are buying from a seller that knows their products. I made the mistake of trying to buy from J&P Cycles. Their wed site listed the wrong grips for my bike and then they billed me for restocking. I went three weeks without my bike because they sent me the wrong grips TWICE!!!!!!!! I then went to Dennis Kirk and got the right grips fast. Dennis Kirk is now my go to website!!!
