Rode  my new Air hawk seat cover on my R65 over for over 300 miles and  more than 6hrs  in the saddle
You may be able to see in the photo my bike has  had an after market seat cushion and cover put on it by one of the previous owners. Â
Short answer is I think it work very good.

My bumb was very Happy
Normally within an hour my but bones are  getting pretty sore.
I have to start setting way back on to the wide part of the saddle to get some relief.
I didn't start getting any real discomfort with the cover installed until over 4,5 hrs of ridding an it still was very tolerable.
Like other reviewers have said you do  rock side to side as you use your butt to transfer weight  as you go thru the curves.
By the end of the day I was getting used to it
As  I let more air out of it the rocking  sensation got less noticeable.
If you are a hard core rider that really pushes hard  thru the corners  you may not like this at all.
The trick  is to get the air down as much as possible without feeling the hard seat underneath.
It stayed  in place very well.
As other reviewers have mentioned the bra straps they supplied  to hold it in place look a little fragile. But could  be easily  changed out to something more robust. Â
The difference in the Airhawk and the Airhawk 2 is that the one is made of Neoprene (2yr warranty) and the cheaper  Airhawk 2 is made of Polyurethane (1 yr warranty). Not sure this maters at all. Â
The company that originally made these (ROHO of Bellevile ILL
before they sold off  this division) makes pads for the medical industry that may also explain the higher cost of the original Airhawk. Â
If I was only going 100 miles or  less I would not fool with this but we have a 2000 mile trip out to the BMW national rally planned for this July and I had to figure something out be for we went.
Now I Â just need to install a set of RT bars. Â
Here is a link to Amazon for the cheaper poly one with the reviews.
At 90 bucks it is  worth a try

We were at the St. Louis area BMW dealer and they had one setting on the counter and I picked it up and was looking at it but when I  seen the price ($190.00 US) I almost  choked. But after I thought about  it over  lunch  and started thinking  about the options and that it was made by a medical supply company.  I had to give it a try.
I ended up getting it from Donelson Cycles
Plus I have been in the ROHO plant to work on their forklifts.
