For a top of the line, premium-level roadracing chain, Sunstar offers the RTG1 series - Sunstar's highest performing roadracing chain - for 520 and 530 street applications (RTG1 = Road Triple Guard). This Works level chain features the TripleGuard sealed ring technology where there are 3 sealing lips and lubrication pools on each side of the ring to maintain top performance in high heat, extreme conditions; the TripleGuard ring type is the best for lubrication and protection. Both the 520 and 530 are available in pre-cut lengths and come in the gold color option (gold outer and inner plates). While the 520 is great for any bike 1000cc or less which already uses a 520 pitch, the 530RTG1 is suitable for the high-performance, larger displacement machines like the Suzuki Hayabusa, Kawasaki ZX-14R Ninja and others in the same class that use 530 pitch. Both options use the rivet-type connecting link and are well suited to handle the demands of the toughest racing conditions encountered on the street.
