Do you have the Royal 45 on hand? I don't. The 55 AX has a 17.5mm X 44mm hole pattern. I just measured a Thunder Tiger 46 and the 55 is wider for sure. Similarly if the Royal 45 is a clone of the older OS 40 FSR then it will also have a narrower crank case and mounting holes.

I don't have the Royal 45 on hand which is the reason I was asking . I also found the dimensions for the 55 AX but was unable to find the manual for the Royal. I was hoping that someone had a Royal and could measure it to see if it was the same as the OS 55 AX.
