But a fat rear street tire with minimal tread grooves look so much better on a sports bike than rain/multi-purpose tires. As long as you know what sand can do and don't lean into any blind curves too hard you will be fine. (You shouldn't be leaning too hard into any blind curves. No tire is going to save you when there is a trike, jeepney or Ceres bus parked in the middle of the road picking up/dropping of passengers and you are over-driving your brakes.)
