The Deuce Risers (HD or knock offs) are 5.5" rise, where 4 - 4 1/4" require no mods (other than maybe turning aorund the plastic wire clips on the back of the handlebars (180 degrees).
I think Deuce knockoffs are as good as (and maybe the same as) HD Duece risers.
They require you to 1) grind the dome off the bottoms (to flat), 2) either drill out your trees just a few thousandths of material (and you could always go back to metric riser bolts if you wanted to no problem), or buy riser conversion bolts, metric to SAE.

And std/tourer drivers may want to convert to interstate throttle housings (which provide just a tad more stretch). And you will still need to check to be sure you have no stretch or bind going lock to lock when finished.

(but not stronger)
https://www.aeromachmfg.com/4_Pullback_Risers_Honda_Sabre_1100_Shadow_ACE_750_p/am-4375c.htmI wear 33" shirt sleeves. I have the deuce 5.5" on one interstate, and the Aeromach 4" on the other. Both are good. I prefer the Aeromach for hard performance riding in the mountains. I prefer the Deuce risers for kicked back cruising with feet up on the hwy pegs. Note, the Deuce at full lock, bring the bar grips around somewhat close to your thighs. No one rides at full lock; you might do full lock in a very slow tight turn.
