## Customer Reviews

### ⭐⭐⭐⭐⭐ Best sportster primary fluid.
*by M***S on January 26, 2023*

Much better than the other oils I have tried. Excellent shifting, good clutch action. Fluid maintains good condition longer than others.

### ⭐⭐⭐⭐⭐ Worth the money
*by G***N on June 7, 2021*

I added this to the primary case of a 2003 Sportster Custom that sounded like a hammer hitting steel every time I shifted gears. It didn't completely silence it but it did make it way quieter and easier shifting.

### ⭐⭐⭐⭐⭐ I like that this is specially designed specifically for Sportster primary cases.
*by L***A on November 2, 2015*

This looks like good stuff to me. Pours out like strawberry syrup. Read the warning label because it's got some toxic stuff in it. Wear gloves and try not to spill it on yourself. Otherwise it's in my bike and working great!
