Hi kmill23,
Correct. Your R3's frame and fork were only designed for 23C tires, though some 25C tires have been fitted, with varying success, depending on rim and tire details.
The latest R3 (and now R2) frame was designed around 25C tires, so frame clearance should be no problem. However, the latest R3 fork is the same as before, designed for 23C.
But the big news is the R2's fork was designed (as the R3 Mud fork) to have as much clearance as the brake caliper itself; no limits from the fork! In fact I just measured almost 45 millimeters of tire space between left and right legs. And the top of the fork is higher than the caliper. Basically, any tire that fits through the brake should fit through the fork.
