V-TWIN BIKES

amsoil solutions for v-twin bikes
There is nothing quite like jumping on a big V-twin and hearing that rumble. The fresh air and freedom to go anywhere you choose bring unmatched satisfaction. Nothing kills that feeling faster than a noisy transmission or an overheated bike. AMSOIL V-twin products are engineered to address the specific demands of V-twin motorcycles. Advanced synthetic technology protects your bike and the spirit of the V-twin biker internationally.
amsoil v-twin motorcycle oils
Hot running V-Twins pose significant challenges to lubricants, especially in low-speed parades, in rally traffic or on long climbs on hot days. Motor oil plays a critical role in cooling big air-cooled engines, and even more so in low-speed operation with limited wind generated to cool the bike. If the oil can’t withstand the heat, its ability to protect your bike is compromised. AMSOIL Synthetic V-Twin Motorcycle Oil is durable and long-lasting. It resists extreme heat and viscosity loss due to shear, keeping your V-twin protected in the toughest riding conditions.
AMSOIL Synthetic V-Twin Motorcycle Oil not only delivers superior engine protection, it provides outstanding protection and performance in motorcycle transmissions and primary chaincases. It is the primary recommendation for V-twin transmissions and primary chaincases.
