Harley shift pivots wear and rattle quickly. After playing around on the internet, stem bearings or "Heim joints" are a popular solution to this problem. I first bought a cheap rod end bearing kit off ebay and you get what you pay for. So this time I researched the quality of this type of connection more thoroughly and these handpiece bearings have the necessary qualities. Moreover, practical application confirmed this point of view. I've ridden about 10,000 miles on these hinges and they're still great.
