SRT Gold Standard non o'ring chain
This chain is recommended for the most power
4,300 lb tensil strength. I prefer a non o'ring chain because an o'ring chain has extra drag. The Sur-ron power is not high at 5 hp and the o'ring chain robs up to 1/2 of a horsepower and is heavier. I can feel the extra drag that the o'ring chain imparts. I will cut to size for free to fit your sprocket.
