NGK spark plugs, the stock choice on many motorcycles. NGK is the original equipment supplier of spark plugs for a very wide range of internal combustion engines. Its products are used on almost all cars and motorcycles that circulate on the roads every day. The NGK brand is also present in the prestigious world of top-level motor racing.
