It's very difficult to find a set of bars, or more likely a bar and riser combination, that will do what you want without changing out cables, and maybe wiring (and you can't really know until you bolt them up). I spent a lot of time measuring, calculating and estimating, and looking for bars that might do the job, and still have enough rise and pullback (I would not go to a bar that required me to lean down and forward like sport bikes, a lot of bars will do that). A number of fairly flat bars would require really long risers, but little pullback. Add to this the fact that once purchased,
and installed, they cannot be returned if they don't work out for you. To get a flat grip, I really hoped to find a set of Milwaukee Twins or Fat Chubby drag bars with integral/welded risers (spaced at 100mm, not 3.5"), but none had the rise and pullback I needed. So I gave up.
Also, remember Harley and Kawi use riser bolts at the tree spaced 3.5", Honda and the rest use risers spaced 100mm (apx 4"). And conversion riser bolts from SAE to metric are available.
I have fiddled with the bar angle in the risers (taller risers on both bikes). I get (wrist) relief by riding one handed, and using my throttle lock.
Here are the valk std/tourer bar OE measurements (IS are the same, but a quarter inch shorter on each end) (OE risers are 3 1/8")
Year Diameter Height Width Pullback Center Clamp Area Factory #
1997 - 2003 1" 6" 33" 14" 9" 3" x 5" 53100-MZ0-000
It's the 14" of pullback that really makes trying to get a flat (or nearly flat) bar to work. And the bars have 6" of rise, plus 3 1/8" risers, equals 9+ inches of rise.
This site is the best I could ever find for looking, shopping and guestimating.
