Rolon "ORANGE KIT" chain and sprocket kit KIT HPXRO 380 for the KTM RC 390, with front and rear sprockets and a 112-link chain. Black nickel-plated inner plates and orange powder-coated outer links give enhanced rust protection and a lustrous finish. Built rigidly for extreme ride conditions and racing, it endures sudden loads, with higher strength, OE fitment and a "dignity drive". The pack includes chain maintenance. The front sprocket is heat treated and hand finished for quiet running. The rear sprocket is carbon steel with induction-hardened teeth, zinc coated and shot blasted for surface fatigue strength. Each sprocket passes 18 production stages and 15 quality checks. Part numbers: KIT HPXRO 380, S 02 560 (front sprocket), S 02 661 (rear sprocket), R520HPXRO-112-2 (chain) Fits: RC 390 (KTM RC 390)
