The solo student pilot reported that, following a normal landing and while the airplane was decelerating, he attempted to exit the runway as instructed by the air traffic tower controller. During the turn, the student lost directional control of the airplane, and it exited the runway and struck a taxiway sign, which resulted in substantial damage to the right wing. The student reported that the speed was suitable for the turn but that he had issues controlling the airplane with the rudder pedals and brakes, which resulted in the runway excursion. The operator reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
