I have used these units in a few bikes including my own in the past. The work well in reducing the clutch pull at the handle. I used a spring scale on an installation to see just how much they lightened the pull. The before and after was a noticable difference of the loss of 3-4 pounds pull on the lever end.
It's a straight forward installation with only the end cover on the trans to be removed and the unit installed in there. Cost is about $15 -$20 depending on where it is purchased.
I found that you can cut a 1/4" allen key off at the short end just long enough to fully seat in the head and this will eliminate the removal of the exhaust system in many cases. The bolts get broken loose with the allen key and can usually be backed out with your fingers once broken loose. It's not necessary to remove the bolts from the cover but just lift the cover up and over the pipes with the bolts still in the cover. Reverse this for the re installation after the unit is installed. Depending on the age of the bike, the side cover gasket can usually be reused.
You'll need common hand tools to do this installation plus a pair of snap ring pliers. Always replace the snap ring in the same position that it was in originally.
A dab of grease on the ramp balls will hold them in place while reassembling the new ramp.
You'll find that the clutch adjustment will be made a bit differently with this unit installed as it reduces the actual throw of the clutch ramp arm because of the added length of the unit. Normal specs say 1/2 to 1 turn after bottoming out the adjustment, you may try 1/2 to 3/4 here with this unit installed.
This pic shows the unit installed in the cover. Note the position of the large snap ring before removing the ramp to install the unit. Also make sure to get the 3 balls in their ramps on reassembly. Sounds complicated but it's very easy to do.

Here's some input on it. On some models it's necessary to round off the corner of the unit so it doesn't contact the cover. Very simple thing to do even using a file.

Well worth the time and cost IMO.
NOTE:
With the bike on the side stand, little or no gear oil will come out when removing the side cover so it's not necessary to drain the trans first.
Here's the same thing for Sportster models.

Then there is the HD reduced effort unit from the dealer which is pictured in this link. It uses different degree ramps and a lighter spring that is installed in the clutch side. A bit more work and cost than the first option and achieves the same results. If you are running a modified motor, this isn't the best selection for you with the lighter spring in the clutch.

For bigger motors (HP) there is the VPC clutch which lightens your clutch pull quite a bit and comes in different models depending on your output.
This link will give you a good idea of how the unit works, the installation of the unit and you can order one there also.
