ProTaper – ProTaper Rear Sprockets - Suzuki - 41-48 Tooth, including 46, 47 and 48 tooth aluminum rear sprockets in black and blue, shared Suzuki/Yamaha fitments, and CS4 steel 38 and 40 tooth quad options, mixes dirt bike and quad gearing in the taller half of the range. For an RM or RMZ, staying between 46 and 48 teeth keeps overall gearing near stock or slightly long, which suits fast outdoor tracks, sand whoops and open riding where you want the engine to pull through a gear rather than screaming against the limiter. Anodized black and blue aluminum sprockets keep rotating weight low, and shared Suzuki/Yamaha patterns in 46, 47 and 48 teeth widen the fitment net. The quad side is handled by CS4 steel Arctic Cat DVX / Kawasaki KFX / Suzuki LTZ400 sprockets in 38 and 40 teeth, where steel earns its place against sand abrasion and the higher chain loads a heavy machine generates. Consistent tooth spacing across the full circumference matters here, because uneven cutting shows up as chain tension that pulses with wheel rotation. Choosing an accurately machined ProTaper rear sprocket restores smooth drive and steadier chain life.
