Extreme heat causes some oils to lose viscosity, which can lead to poor shift quality and compensator noise. AMSOIL Synthetic V-Twin Motorcycle Oil resists viscosity breakdown despite the extreme heat and stress of summer riding. By maintaining viscosity, it promotes smooth, conident shifts and helps reduce compensator noise. In fact, it provides 6X better resistance to viscosity breakdown than Harley-Davidson SYN3.*
