Hey guys, thanks for all the great feedback!!
@Batman, I agree they are good looking bars. And, they're exactly what I'm after. The seller offers options for metric or Imperial spaced knurling, or no knurling at all. So that should be fine. I did wonder about the cables for the buckhorn bars ... I'll keep that as an option.
@Lancer, Yeah, I agree it would be a close call. I'm currently running some Biltwell Z-Bars with a 6" rise. Everything is fine but the brake fluid line is at its maximum length with no weight on the front shocks. These bars have a 5.8" rise but more pull back. I reckon it would be close. And ... jeepers, the cost of new cables is expensive! The supplier's site does have a direct measurement from riser to control box, for comparison. I'll check that out and hope for some leeway. As for the cost of bars, here in Australia, everything is expensive ... luckily, I didn't buy the bike to save money
@gtenginerd, thanks for the tips. As I mentioned to Lancer, the site does offer a spec on distance from riser to controls, so I'll check that out. The risers you linked to look very similar in size to the stock risers for the buckhorn handlebars. Also, I've used the same bars (trackers) with some home made 40mm risers. That's the closest I've come to a perfect fit.
@Slowlane ... nice looking bars. Let us know how they feel once you get 'em on!
