ProTaperProTaper Sprockets, including hard-anodized front sprockets, colored aluminum rear sprockets, CS4 steel rear sprockets, and ATV-specific gearing, is the heart of your final drive. Gearing decides whether a bike pulls hard out of a tight corner or stretches its legs down a long straight, and this range lets you tune that trade-off precisely. Front sprocket groups for Honda, Kawasaki, KTM / Husqvarna / GasGas, Suzuki and Yamaha run from 10 to 15 teeth, so single-tooth changes at the countershaft become an easy, reversible experiment. Rear sprocket families are split by machine and tooth count, from up-to-40 tooth setups through 41-48, 49-52 and 53-and-up ranges, with separate mini and youth options for KTM 65SX, Gas Gas MC65 and Husqvarna TC85 bikes. Anodized aluminum rear sprockets in black, orange, red, green and blue cut rotating weight, while CS4 steel rear sprockets and the ATV-specific line serve Suzuki LTZ400 and LTR450, Kawasaki KFX, Honda TRX250R and Yamaha YFZ450 quads where torque and abrasion demand durability. Matched ProTaper gearing sharpens throttle response and extends chain life.
