Started using NGK plugs in the 1970's on my two-stroke motorcycles. They always lasted the longest and provided the best performance. Tried other plugs from Germany, Japan and the US, and nothing came close to the NGK plugs in performance or longevity. I still use them exclusively. Now I have a Sport Touring bike and I still only use NGK because they continue to provide the best plugs and best performance in my opinion.
