Reply To: GT250R Axle nut size Oct 22, 2024 at 11:33 PM #15292 Jim👤 Member Topics: 11Replies: 142 Why they went with 23mm is a real mystery! I had every inch & metric tool you can think of. Except for that bastard sized 23mm! Now that I have a combo wrench that size I’ve also used it on my SYM for valve adjusts and oil screen cleaning.
