Run The Right Oil In Your Two-Stroke Motorcycle Engine

Run hard and fast with the perfect blend of premix or injector oil.

Magical and mystical, two-stroke engines are like the unicorns of the motorcycle world. With as few as three moving parts, they are the ultimate in internal-combustion simplicity, and because they have a power stroke every 360 degrees instead of 720 degrees for a four-stroke engine, they make terrific power for their size. An essential ingredient in keeping these unicorns alive is two-stroke oil. The later two-stroke streetbikes used oil-injection systems that dispensed the right volume of oil to the engine based on throttle position and engine speed, whereas racebikes, including current products from certain bike builders, require premixing oil with the gas. It’s not so very hard to do, and with the benefits of riding a two-stroke, why, there’s no equal! Read on for some top oil choices.
