ProTaper – ProTaper Rear Sprockets - Kawasaki, including 46 through 53 tooth aluminum rear sprockets in Kawasaki green and black, including shared Kawasaki/Suzuki fitments, covers the whole practical gearing window for a KX in one place. Tooth counts run from 46 up to 53, so you can gear tall for fast, sweeping outdoor tracks or short for stadium-style circuits and tight woods without leaving the range. The Kawasaki green anodized sprockets in 48, 49, 50 and 51 teeth match factory bodywork for riders who want the bike to look finished, while black options extend to 52 and 53 teeth for aggressive setups. Shared Kawasaki/Suzuki patterns in 46, 47 and 48 teeth add flexibility across garages that run both brands. Each sprocket is machined from hard-anodized aluminum, which keeps weight low at the wheel's outer diameter where it affects suspension response and how quickly the bike changes direction. Tooth flanks are cut to seat chain rollers squarely, spreading load and slowing the hooking that turns worn sprockets into chain-eaters. Bolting on a true, correctly geared ProTaper rear sprocket brings back crisp drive and quieter, more consistent chain travel.
