Helibars versus Convertibars
Helibars is on the left. Convertibars is on the right.
The Helibars are taller than stock and I have had them since 1999 until now (June 2011). While they are more comfortable than stock, but on long distance ride, I always wished that they could be a little bit taller.
The Convertibars are about 2 inches taller and they are so well made. The adjustability is so much more flexible: the bars can be lowered or raised, the angles can be adjusted from 0 degree to +4, +8, -4, -8. The bars can also be moved fore and aft. The bars itself can be rotated 360 degree around its own axis.

Unlike the Helibars that use 2 bolts to clamp to the fork. The clamps of the Convertibars use a single bolt that draws 2 vertical steel bars together and therefore apply a uniform clamping force on the fork. Same for the clamps of the bars. There is only 1 bolt to torque to clamp on the fork, and another bolt to adjust the height of the bars independently. Brilliant.

Bar end of Convertibars
The female thread inside the bar end of convertibars is so much deeper than my ThrottleMeister bolts. The bolts are metric M6 - 1.0 thread flat head socket cap screws. The ThrottleMeister bolts are 60mm long and I needed 80mm for them to reach the female thread inside the Convertibars. Nobody has them. I finally found them at
http://www.fastenal.com and they have local stores everywhere. The customer service is topnotch. I called a local store on the phone and ordered 2 to be picked up locally and they did not even ask me for my VISA. They just took my name and ordered them for me.
This is the only drawback of the Convertibars. There is no reason for the female thread inside the bar to be this deep. They should at least provide some adapters or long bolts as there are no bar ends with that long of a bolt. If they are any deeper, the Convertibars would be unusable, because the longest 6mm bolt available is 80mm and it barely reached the female thread inside the bars to reinstall my bar ends. Nobody in the world make a 6mm bolt longer than 80mm. Again, may be it's my bar ends as mine are ThrottleMeister's heavy duty bar ends and they are longer than stock.

Helibars
This was how my Helibars were installed. I raised it up 1/2 inch from the top of the triple clamp just to gain a little more height...

Measurement...
Before the Convertibars were installed, I put my XX on centerstand, with the handlebars pointing straight ahead and measured the distance from the ground to the left handlebar so I could get a baseline for later comparison.
The distance was 998mm (2 mm short of 1 meter).

Convertibars Left side
There were so many ways to install the convertibars and finally this was what it looked like.

Convertibars right side
I had to remove the throttle cables at the throttle tube and rerouted them from the front of the right fork to behind the right fork. The brake lines are Galfer with 2 inches longer than stock. Same for the clutch line which is Galfer with 2 inches longer.

Convertibars left bar end distance to ground from centerstand
Now with the convertibars installed, the measured distance from the top of the left bar end to ground, from the centerstand, is now 1010mm. Which was 12mm taller than the Helibars. This may not seem much, as it's only 1/2 inch taller. But the bars are further back toward the riding position and that makes a big difference. See other pictures of the convertibars taken from the front and top.
The bars can be adjusted to go higher for another inch, but my Galfer brake/clutch lines and throttle cable ran out of room. I will need longer brake/clutch lines and longer throttle cable if I want to go higher. The current brake/clutch lines are 2" longer than stock and the throttle cable is stock.

convertibars top view
See how further back they are. Compare this picture with the picture below, which was taken with the Helibars. Pay attention to the sticker on the left side of the gas tank for reference.

convertibars front view
We can clearly see that the convertibars are higher, comparing to the same picture taken with the Helibars.

Convertibars versus Helibars
The left side is Convertibars. The right side is Helibars. Note that I raised the Helibars about 1/2 inch above the fork top for more height.

Longer bar end bolts
I had ThrottleMeister installed on the Helibars. The bar end bolts go into a female thread inside the bars. The bolts were too short at 60mm (as the female thread inside the Convertibars is much deeper than Helibars)so I had to get another 2 M6 - 1.0 thread x 80mm flat head stainless steel cap screws for them to reach the thread. 80mm is the longest bolt available and they fit just fine.
80mm is the longest bolt available in the world with M6-1.0 thread. The 80mm bolt just barely reached the female thread inside the Convertibars to reinstall my ThrottleMeister bar ends. Just barely. May be the ThrottleMeister heavy bar ends are longer than stock, as I don't have the stock bar ends anymore to compare with.

Test drive with Convertibars
After 2 days of commuting to work for a total of 100 miles, I have the following observations on these Convertibars comparing to the Helibars:
1) The weight was off my arms by at least 70-80%
2) The steering is so much lighter (due to less weight applied to the handlebars from my upper body) and I felt I could steer faster and easier
3) Counter-steering is easier because of more leverage due to higher bars
4) My neck is more comfortable as I didn't have to bend up my head to look straight
5) More wind blast
6) Turning my head when lane change is easier as my body is straighter
More notes after a 500-mile ride...
I just got back from a 2-day 500-mile ride to Salton Sea with the Convertibars.
- In twisties, I felt so much more confident as the lighter steering was so much easier to control and the bars gave me much better leverage while making turns.
- I did not feel any soreness on my back. Nor on my arms.
March 1, 2012 - After 5000 miles...
I put in 5000 miles since I installed the Convertibars. These 5000 miles include a few multi-day long trips averaging 400-500 miles/day. I absolutely love these bars. I no longer had a sore and stiff back at the end of the day's ride. I wish I did this years ago instead of enduring 12 years of Helibars. Helibars simply cannot compare to the flexibility and the adjustability of the Convertibars.
No, I don't work for Convertibars, I did not get the bars for free and I did not get paid to write this review either. I'm just a motorcyclist like everybody else... and I'm putting up this site just for fun, among other things...
