Hold your arms out in front of you like you're gripping some bars. Have your palms flat or parallel to the ground. The Superbike bars are flat and this is how your wrists are going to be. Now, rotate your wrists outward a bit, say 30°. Better, huh? This is how the Euro bars will place them. It's a more natural and comfortable position for them.
I bought some Superbike bars many years ago because all the bike mags back then raved about them. Eventually I got a BMW and wanted to put low bars on it. BMW bars are rather special, not 7/8" but rather a slightly smaller 22mm. You must use this smaller size for the controls to fit. So, I had to get actual BMW replacements (Magura) and they turned out to be the Euro bend. They were a revelation, the most comfortable low bar I had ever used. I had those Superbike bars for many years and they would get installed on any new bike I got, but only temporarily until I could get some Euro bars for it. I finally sold them to somebody and good riddance, lol. I now keep extra Euro bars "on the shelf".
