Customer Reviews


very helpful on longer rides, don't leave home with out it!


WORKS OK, NOT AS GOOD AS THE Kurykyn chrome model-


Makes cruisin WOW!


doesn't fit Harley grips.


Satisfied and would recommend this product.


I purchased the universal throttle boss, and I am very pleased. My wrist doesn't get tired anymore after riding.


Throttle Boss slips on the grip even with the addition of carpet non-slip material. It is essentially useless. Because it didn't cost much, I chose not to return it.


Relaxes your grip.


The throttle boss is a excellent item. It lives up to its intended purpose. It works so well that the reason I'm buying another one is that someone else thought so too and "borrowed" mine. In fact this is at least the #4 throttle boss that I have had to purchase over the last 5 years. Thanks :)


Great product. Keeps my hands from cramping on long rides. Well worth what little it cost. I only have to be careful when slowing or stopping, to make sure I take my hand off of it.


It seems like a good idea but it sort of gets in the way during normal throttle use. I don't recommend it.
