## Customer Reviews

### ⭐⭐⭐⭐⭐ Finding Neutral more often
*by M***P on April 1, 2025*

2017 iron 883. After changing the oil its been easier to find neutral compared to almost never being able to get into N when in traffic. I can hear and feel the shifting is less clunky as well. Awesome product. Will buy again when its needed.

### ⭐⭐⭐⭐⭐ Higher price but..
*by A***R on September 6, 2024*

Seems to be doing a better job than what I’ve used before. Seems to be a lot smoother. I have ran Lucas primary that didn’t seem to hold up. Ran motul motor oil that held up decent. But once I put this in I could tell a difference. Only have about 1500 miles on it. I might end up switching everything to klotz.

### ⭐⭐⭐⭐⭐ Works great!
*by T***5 on August 27, 2024*

Trying this in my '03 Ultra. After 2 weeks, shifting seems smoother, the first gear "clunk" has quieted dramatically and neutral is easily found. I will get more when I'm due to change my primary again.
