Mike,
The renthals I put on are standard Honda bend, which is not a gnats whisker from the KTM ones. I changed because I didn't like the standard bend, as it made my wrists ache. The width can be anything you like, I actually kept them to the same width as standard by only cutting off half an inch to accomodate the bar ends. The KTM bars were given to me to try out before making any irreversable changes, they can be put on without altering anything on your bike, and can be taken off again just as easily. For a permanent job, Tobers method is far better. An added bonus is that Renthals weigh considerably less than the standard bars.
HTH
