The front and rear drum brakes provide reliable stopping power, while the oil dampers in both the front and rear suspension ensure a comfortable ride over varied terrain. Available in a striking Candy Sapphire Blue, the ST70C is a sight to behold and a joy to ride, embodying the classic Honda aesthetic. ####
