Q. Why my RR 310 BS6 stopped when I am in high gear with low speed inspite of having slipper clutch ?

Slipper Clutch helps by allowing the clutch to partially slip until the engine speed matches your own speed. In normal clutches, the engine braking force is transmitted to the rear wheel via chain drive (or shaft drive) which causes the rear wheel to shake, jump or lose traction. Slipper clutch reduces sudden forces on the inside of the transmission but it does offer fee movement ability to rear wheel. Just like another non-slipper clutch bike, a bike with a slipper clutch will too stop while jumping from high gear to lower gear from high speed but the stopping time will be a bit more as compared to a non-slipper clutch bike.

Maybe you have not changing gear @ right time
