Fits my TERYX 4s perfectly.
I lost a front hub cap on my last ride and decided to try these. They are 4 for the price of an oem one. Looks a little different than the original but close enough. I have been in a few rides and haven’t lost it which is great.

Worked like a charm
As others have commented.... these do in fact fit on the Brute Force 750 wheels but stick out 1/4" further than OEM Brute Force center caps. Since there are so many more Brute Force 750's than Teryx 1000's I'm wondering why this company doesn't mold the replacement Brute Force 750 caps. I'm using these on my rear wheels and I'm happy to not be paying Kawasaki's outrageous price for a poorly designed center cap.
