I have Complast tracks on my Honda 500 Foreman. Sprocket size and attachment points are specifically designed for that specific make and model machine. Guess my point is, I would first contact the company that makes the tracks you are looking at to make sure they can be adapted to fit your particular machine. My Foreman tracks won't work on my P500, different attachment points, steering attachments different, etc. don't know how much the tracks are you are looking at, but mine cost $4000, hate to you spend that kinda money and they won't work. Just saying!!!I have no knowledge if they work on a Pioneer, but do look forward to seeing them in operation...…....
