I recently bought a 1997 Indy Ultra SPX, and the track is worn done to almost nothing. I'm looking at a used track off of a 1991 Indy Sport. The guy tells me it's 121x15.75 with 2.52 pitch. I know that the track on my sled now is only 15 inches wide, so I need to know if this track will fit. Thanks

it should fit, but honestly it's not going to be a very good track. look for a 121 X 15 X 2.52 pitch with anywhere from a .75 to 1.25 inch lug height and you'll be much happier.

The Camoplast Ripsaw and Cobra versions are great tracks and deals can be had on Ebay. Also anything off of about a 99 and up Polaris or arctic cat is going to be a decent track as well.

I can second that the closer you get to 1.25 the happier you'll be. The .75 doesn't do much on anything but trails.

okay, i might take a look at this one, the guy only wants $50 bucks and it's close, but I'll try to find one with more tread. anything is better than what I have now. thanks for the help

The track should fit on the machine though, right? Polaris didn't change anything on the drive system from 1991 to 1997 on the Indies, did they?

Nope, no changes that would effect that, so you're good there.

Like he said but anything over 1 3/4 will probly tear off for regular trail riding.
