I've gone through a LOT of chains in my past 24 years of racing, tried em' all and for the big hp abusive bikes, I prefer Sunstar steel sprockets, and my hands down favorite chain is the Regina ORN Gold. Adjust it once from initial stretch, and forget about it ! One TOUGH chain! One true fact I've learned over the years is a cheap chain will quickly destroy your sprockets ! Take my advice, run a high quality o-ring X-ring whatever chain, and your sprocket life will double over a cheap chain !
