Welcome aboard.
That's a nice example you've got there. On the subject of OE bar ends - I wouldn't bother as they're only plastic buttons that block off the open handlebar. You'd be better off fitting something from R&G, if you want crash protection, or something heavier if you want to damp out any vibes.
By the way, have you seen this other bargain from Doggy?

Do you have plans for any other mods?
