SNOWMOBILE DRIVE TRACK WITH PRE-MARKED STUD POSITIONS

A drive track for a snowmobile includes a plurality of pre-marked stud-mounting sites, each site being pierceable or drillable to define a passage or bore for receiving a stud. The pre-marked sites are locations where drilling of the track does not unduly compromise track strength. The pre-marked sites can be cylindrical protrusions on the outer surface of the track to facilitate drilling out of the bores using a track bit. The protrusions can be located in spaced-apart pairs on a middle portion of the track in a protrusion pattern that repeats every six pairs. The drive track having these pre-marked stud positions enables end-users to install studs without damaging the track or without having to purchase and install an aftermarket pre-pierced track.
