Fits:
14-19 XP 1000
15+ 900S/1000S
 
2 Seater ONLY
 
These are very nice framed uppers that open with the door.  No unzipping nonsense every time you want to open the door to get in or out.  However, the window can be rolled down and tied out of the way if desired.  Very similar to the oem Polaris uppers but a much better fit with the Spike uppers.   These have a piece that mounts to the top of the cage that creates an excellent seal.  In my opinion the best on the market.
 
Very easy to install
Only works with factory doors and cages
