I know nothing of frames being available from Polaris. I was just joking about current XP guys converting over to the XP 4 for the wheelbase increase.
I can say this. If you roll the machine with the stock cage it can sometimes tweak the frame at the mounting points. This is no biggie if your a fabricator, you can just do your magic and voila, good as new. But for most dealerships, they will not fix it but require a frame change. Most insurance companies do the same thing. This is not a Polaris thing, it happens to every SXS made, its just that so many of those machines are sold that by sheer numbers, you see old frames laying around in not that bad of shape. I just saw one yesterday in the Phoenix area and it could have been used by any racer that has the ability to fix things (it was a regular XP frame so dont get excited
).
So, let the XP 4 get out there in some numbers, let the casual non racing folks have a few tip overs (not wishing any hard crashes on anyone) and if your in good with your local dealer, they will just give it to you if they dont have to send it back to Polaris or if its an insurance job, they sit on the old parts for 90 days then off to the trash and scrap yard they go.
