The S20 EVO loved by so many riders has evolved again. Due to its superior agility, the S21's ease of handling and the contact feel when cornering surpass even that of the S20 EVO. The rear tire was developed with Bridgestone's ULTIMAT EYE™ technology, while the compound succeeds in generating better traction and while improving abrasion resistance for longer life. This marks the birth of a new premium sports radial, one that brings out the best in machine performance in pursuit of the joy of riding.
