300ex and 450r Sproket question

[tedscrappy300]

I run a 14 tooth sproket in the front of my 300ex. its getting warn so im gonna buy another one. Im sponsored by RK chain and sprokets and they said they dont sell a 14 tooth sproket for a 300ex and they said that the 450R stock wont fit. I know were I can get them, but I was just wondering if a 450R stock front 14 tooth sroket will fit a 300ex?
