I have some strange disorder that causes me to alter the handlebars on just about every motorcycle I've ridden. Even my poor '67 BSA lost its American-style cowhorn bars very early in my possession of it. Being a sail lacked entertainment value, and besides, the cool guys over in Old Blighty would never be caught dead with something so gauche. I even tried the Clubman downturned bars for a bit, but since I was also commuting into Chicago at the time with the bike, those didn't last long.
I won't even mention how I fitted riser-type handlebar mounts to my Velocette Thruxton so I could put low, Euro-touring-style bars on it in place of the authentic but unbearable clip-ons. (Nor will I discuss the 38mm Mikuni I applied to make it sort-of rideable.)
But that's a handlebar-obsessive. Jeez, even on my '98 Gold Wing 1500 (that my ex insisted I buy to ride her around) I altered the bars, cutting and rewelding them to get a better angle. (the later, more-liked GL1800 had bars that had a satisfactory shape and were left unmolested.)
My FJR came to me with an MV plate installed, which seemed to be a vast improvement over the other, stock FJR I'd ridden prior to getting this one. In short order, though, I wound up adding Black Path 1" risers to the MV plate, which was the absolute limit I could stretch out of the throttle cables. I'd always planned that if I decided to keep the bike for a long time, I'd pop for custom +3" cables from Motion Pro, a $200 upgrade, and then fabricate my own, Heli-esque plate to combine with the riser blocks. 12,000 miles later, I still haven't gotten around to it.
With the Touring screen that came on the bike, in summer weather and going screen-down, the MV+BP combo is pretty well right for me. With the screen up, or with the someday Rifle barn door, I think hard about moving the bars rearward as described above.
