The adjustable reach levers are nice (Kury, Add-on and someone else, and you have to cut a tab off one of the levers, as they are made for Goldwings; 1-minute easy job), but the truth is the Kury Wide (chrome) (nonadjustable) direct replacement for OE levers are very nice and beefy, and about the same reach as the adjustables on the #3 middle setting. And I don't think the adjustables are as wide as the straight replacements (Kury Wides).

Here is the how-to on cutting the tab off. And note that some have a small brake light issue; when releasing the lever, the brake light stays on for 2-3 seconds before switching off (when I had them, it was not how tight or loose I mounted the lever, it required I take the lever and do a bit of careful filing where it fit into the lever mount) .
