What are motorcycle additives, and do they work?

Similar to passenger car additives, motorcycle additives are small doses of products that can be added to the fuel and/or oil tank to boost the performance of your motorcycle engine. Additives can contain a variety of ingredients that work by enhancing the functions of the fuel used in the motorcycle and "stabilizing" the fuel by slowing down the oxidation process. All fuels are subject to oxidation over time, producing a gum-like residue that can block the entire fuel system. Although this process cannot be stopped, it can be slowed down with the use of fuel-stabilizers. Additives can also contain detergents, dispersants, and other cleaning agents, as well as ingredients that can boost a fuel's octane number.
