Engine knock is especially noticeable in some motorcycles during idle or low-rpm
operation and high-temperature driving. Most modern bikes are equipped with
sophisticated knock-detection systems that can alter spark timing and the air-tofuel mixture until knock ceases. Although these systems protect the engine from
damage, they can also cause reduced horsepower and poor low-rpm operability.
AMSOIL Motorcycle Octane Boost helps reduce the need for knock-detection
systems to compensate, ensuring maximum low-rpm power and performance in
modern bikes.
