For the 2008 Rev, I understand it is fitted with a 120″ track. Is there enough adjustment in the rear skid to fit a 121″ track if the pitch were compatible?
Why change it to a 121? The new track is super light and strong – all you’ll do is increase weight – and you’re paying for less weight when you buy an XP.
It will be difficult at best to use any other track as the drive axle and the track pitch are unique. In other words you can’t change the sprockets with this axle to match an old pitch track.
You should note that only Woody’s has studs right now which will work with this track.
