RIDE HARD. RUN COOL.

There’s nothing quite like jumping on a big V-twin, feeling the fresh air and freedom to go anywhere you choose, hearing that rumble - and transmission noise. AMSOIL V-twin products are engineered with synthetic technology to protect your bike, prevent overheating and quiet noisy transmissions. Get the best for your bike or learn more below.

Protects Powerful, Hot-Running V-Twins

 

Harley-Davidson* air-cooled V-twins can get extremely hot, especially when idling or traveling at low speeds. Motorcycle oils that can’t handle the heat may fail to deliver solid wear protection. AMSOIL Synthetic V-Twin Motorcycle Oil is formulated to withstand extreme-heat conditions beyond the hottest temperatures motorcycles typically experience, providing peace of mind that your motorcycle is protected no matter how extreme the operating conditions.
