How many studs for a 121 track
The 121 snowmobile track is a classic and has been the most common trail tracks for decades. It features a 2.52" pitch (the spacing between lugs) giving it 48 windows to stud.
While it used to be the go to track for all flagship trail sleds, it has recently fallen out of favor for longer versions.
