Sprocket available in 520 x 14 and 15 teeth SUPERSPROX Rr. Sprocket available in 520 x 41, 42, 43, 44, 45 and 47 teeth Teeth and Sizes Explained... ** A +1t front sprocket only change is the same ratio change as -3t rear sprocket only change. (Freeway Ratio Kit) ** A -1t front sprocket only change is the same ratio change as +3t rear sprocket only change. (Quick Accel Ratio Kit) ** A smaller rear sprocket or a larger front sprocket is for Freeway Ratio** A larger rear sprocket or a smaller front sprocket is for Quicker Acceleration ** A 520 size chain is approx. 2mm narrower than a 525 chain, and 4mm narrower than a 530 chain. Less mass equals lighter weight equals easier to spin, but the ratio (teeth size) change makes the big difference. The sprocket width matches the chain width where it rides on the sprockets, thus a 520 chain must use 520 sprockets, and a 525 chain must use 525 sprockets, etc... ** RPE Motorcycle has chain and sprocket conversion kits available in 520 , 525 , and 530 sizes for most motorcycles. ** A larger rear sprocket number of teeth size requires a longer chain, however +1 or -1 tooth on the front sprocket only will use the same chain length ** A ratio change to enhance your low end (Quick Accel) will reduce your top end, and adversely.. a ratio change to enhance your top end (Freeway Gearing) will reduce your low end throttle response. Stock Gearing is the "Happy Medium" of both with the least amount of compromise on either end Optional chain colors: Gold JT X-Ring (costs $10. more), , Silver JT X-Ring All JT X1R2 520 chains include a CLIP Type and a RIVET Type master link.
