your best bet is to go with the adjustable style mentioned in this thread or go custom with a set of fat bar mounts and adapt everything to them, kinda like a stunt bike. but yes, it is possable

 

With enough drive,effort, ingenuity, and/ or money, anythings possible. Those Gilles or the Heli-bars seem the most versatile/adjustable but expensive.

 

i've got the same issues with my 06 636! i can ride 3-400 miles in a day, and my neck is killing me. im in the works of putting the oem clip ons above the tree. if this doesn't help i want to look into "riser" clip-ons. i have found another brand that fits my bike.... http://www.convertibars.com/FitYourB...+Next+Step%21+

maybe worth checking out

 

i really want to know how it rides and looks with the clip ons above the tree hit me up when you are done.

also a few things that extended my riding you should deff try these first.
