I have an '07 IQ CFI 600 and am thinking about upgrading the track. I am looking at Camoplast 1.5 Intense and 1.75 Back Country. Off-trail is where I ride the most and my stock 1" lug track just doesn't cut it. Will I have any clearance issues with the 1.75? Do I have to upgrade my drivers? What else should I be looking for? Any input is appreciated thanks.
