Dougl,
Pretty cool looking bike, it's funny but I'd say that your bars (in picture 4) look wider than the stock ones fitted; but the width of the Ultra Classic Style Narrow bars are 31", where as the stock on mine are 34" (tip-to-tip). It must be an optical illusion as the centre part of the Flanders bar is much wider than stock.
Given that the RIII uses standard 1" dia bars, at a guess do you think most HD bars might also fit the RIII risers as well ?
Thanks for the advice, I'll have to pass on the dealer in Reno, it's a little far for me as I'm based in the UK

Nice looking original Bonnie (I think) from the 70's!!
Cheers
Steve
