Will this fit a 2005 honda crf 450r ??

I believe the stock chain for those are 520/114 so yes this should fit

Does the manufacturer specify this as suitable for x type (520xso) chains?

Xso.. is an X type chain means o-ring

Does this come with the connecting master clip?

Be aware that RK chain master links are a press-fit. Even the clip-style require a you to press the link-plate onto the connecting link pins. If you don't have a chain press tool, you can use a C-clamp and a small socket as a press. Once the link-plate is installed then put on the clip with the rounded closed end in the direction of travel.
