Synthetic Motorcycle Oil

Outstanding Performance for Harley-Davidson* and Other Bikes


AMSOIL Synthetic Motorcycle Oil is recommended for most motorcycle brands, including Harley-Davidson,* Indian,* KTM,* Ducati,* Aprilia,* BMW* and Triumph.* With several riders among our ranks, including our Board Chair Dean Alexander, we understand firsthand the tremendous power and heat motorcycles can generate – and the unique challenges they present to lubricants. That expertise has resulted in a lubricant prized for its ability to fight wear and heat in powerful, hot-running Harley-Davidson and other bikes. You can trust its ability to protect your bike no matter which brand you ride or how hard you ride it.

AMSOIL Synthetic Dirt Bike Oil’s superior friction-durability helps minimise clutch slippage, fade and chatter, giving you consistent clutch feel during takeoffs or when manoeuvring around obstacles on the trail. Testing with professional teams in Monster Energy Supercross helped fine-tune AMSOIL Synthetic Dirt Bike Oil for consistent clutch feel and outstanding wear protection.
