Here's another company that makes fabulous clutches, FCC
. They may be not as well known as say, STM
is a global company based out of Japan, and are actually a tech giant. The following is based from their web page: F.C.C. Co., Ltd. manufactures clutches through an integrated system extending from research and development of frictional materials to assembly of clutches. The scope of our business has been steadily expanding in stride with the development of the automotive industry, enabling F.C.C. to claim the top worldwide share in motorcycle clutches. Our global production system consists of 22 manufacturing facilities covering 10 overseas countries in addition to our Japanese facilities. F.C.C. develops most of its own production equipment and has built production lines ensuring both high quality and low cost. This, we can say with pride, is F.C.C. technology. Our rigorous simulations are designed to make clutch features scalable under imaginable operating conditions, and our testing capability extends to the harshest conditions. This, too, is F.C.C. technology. Although we hold specialized technology in a wide range of fields, to us its mere possession matters little. What matters instead is that all vehicles equipped with our clutches provide its occupants the joy of safe and pleasant riding wherever they are driven https://www.fcc-net.co.jp/en/product/motorcycle.html
After five years of combined street/track use I can affirm their product is well built, durable, and reliable. I've as yet have not had to adjust it, though I clearly understand that there will come a time. In all fairness, I do possess a moderately high degree of mechanical sympathy
, my father instilled in me that it was not acceptable to beat on, gnash,disregard operating procedures, or generally abuse a mechanical component, tool, or other such device.
