The rear brake caliper on the 300 is identical to the front. So the front is underpowered and the rear overpowered. When I need to stop NOW it's 100% front brake for me. On a short wheelbase bike like this, maximum (threshold) braking means the rear tire is floating just above the ground. Watch how the MotoGP guys do it.
For the most part, the rear brake can be safely ignored. The rear is really only useful when performing very low-speed maneuvers. Lightly dragging the rear brake will help stabilize the bike, e.g. when performing a U-turn. And at times I will use it to flash the brake light once I'm already stopped at an intersection.. make sure the cars behind don't rear end me.
Now this doesn't mean you should go out and grab a handful of front brake, on cold tires no less. Apply pressure progressively, allowing the weight/traction to shift to the front contact patch as you squeeze the lever harder and harder. With some practice at threshold braking (and some minor suspension upgrades, esp. fork oil viscosity and height) you'll be amazed how confidently this little bike can brake.
