I've installed ConvertiBars on my 2004 R1 and they work very well, but require some effort to achieve the full benefit.
I fitted the 10-degree bars with 6.5-inch risers. To get anywhere near the maximum height required the extended clutch cable from ConvertiBars as well as an extended brake line that I purchased from Spiegler. (The extended clutch cable isn't as slick as the stocker. There is sometimes a perceived lag in the clutch action with this cable, particularly when the bike is cold.
Fitting the bars also required a pair of spacers that I fabricated to raise the back of the nose fairing to provide clearance for the higher bars. This works reaosnably well, though it distorts the front of the fairng in the headlight area.
Perhaps the biggest challenge was coming up with a new mount for the steering damper that normally bolts to an extension from the bottom of the left stock clip-on. I ended up buying a steering damper mount from Storz, but this didn't work because the centerline of the hole to which the steering damper mounted was too close to the fork tube centerline. The solution was to weld a 1/2-inch square hunk of aluminum rod to the Storz mount and space the damper mounting hole further out. This worked perfectly.
Otherwsie, I also had to relocate the throttle cables from ahead of the forks to behind them. Same for the wiring from the handlebar switch modules.
It was all worth it, however. With the bars pulled back and set as high as they will go, the bars are actaully too high for highway use. At 80 mph, you are being blown off the bike. However, dropped down a bit, they feel very good, both on the highway and in the twisties.
I recently completed a four-day 1600-mile trip on the bike and the handlebar position was very comfortable.
Now I need to lower the pegs to create some more leg room.
