Swapping handlebars

I'm thinking of changing the bars on my er5 for renthal low ones..
Will I need new bar end weights are they standard sizes..

 

you may need smallerb ones as the renthall bar end hole is a bit narrower

 

See http://www.northwestbikers.net/index.php?threads/renthal-fatbar-conversion.24794/#post-384059

I know you are not converting to a Fatbar, but the bar end fitting on the standard Renthal is the same.

 

Would these do the job?

What I/D are they for? As I recall the Renthal I/D is 14mm.
