I bought Wild1 Chubby Reapers slightly used for $250 shipped off ebay, they used factory clamp. Don't give up on Wild 1's You just might find a deal.
Good idea...but harley in their infinate wisdom decided to make the bars on 15 up RG different. So unless the bars are made for 15 up RG's it requires a special clamp. Factory 47 and Road 6 are two that are actually making bars for 15 up RG's.
I think the reapers and factory 47 are best looking RG bars available. Really like my reapers, but would have went with factory 47 if knew about them at the time, the curve in the vertical section is bad azz.
Don't forget about Vindikta handlebars as well. 1.5" diameter, slotted for the pins, etc.
That being said, I have Factory 47 signature bars, 14" rise and love 'em!
+1 on the Vindikta...don't have the coin currently but after 6 months of shopping bars they are the builder I am going to purchase. Really responsive via facebook messaging should you have questions for them.
