T.O.P. Photon EX optional drive belts
T.O.P. Racing introduce new optional front and rear drive belts for the Photon EX touring car. The softer material reduces transmission drag for better overall efficiency without harming power transfer capabilities. Also new is a white colour belt made from an even softer material that is especially designed for racing with stock motors.
