Yes, Aladyblond. you would have to put all of the motorcycle skins in a folder (I use C:Program FilesHaptekplayerdatastandardskins)
Then make a script text file for each skin, and drag the text script into the window!!
Script:
#Haptek Version= 1.00 HapType= command FileType= text
settexture [figure=Cycle2 tex=[C:Program FilesHaptekplayerdatastandardskinscycle22.jpg]]
Replace "cycle22" with the name of the JPG for the motorcycle skin.
I will try this out to make sure it works. It should.
EDIT:
oops.,I guess not. I can get Cycle 22 to go on the bike with the script, but not Ted's Cycle25, I don't know why. Someone may know the right way.
It might be possible, if you open the bike, drag all of the skin JPGS on the bike, THEN add the girl, then the scripts may work.
OKAY, the scripts work for me if:
1. I open the bike. Drag all of the skins I want use on the bike
2. Add the girl, and the backgound. Then drag each text into the haptek window to change the bike skins!!!

P.S,, Jack included scripts with his bike skins. So all you gotta do is put the bike skins in your skins folder, as noted above, and drag the scripts Jack made into the haptek console or window.
