EK Chain manufacturing was at the forefront of chain sealing technology and design, being one of the first to market with an O-ring seal design and production in the early 1970’s. The EK O-ring was even used as the genuine production chain on the iconic Kawasaki Z1. Greatly improves chain life compared to unsealed option.
