ProTaper – ProTaper Rear Sprockets - KTM / Husqvarna / GasGas - 41-48 Tooth, including 46, 47 and 48 tooth aluminum rear sprockets in orange, red and black for full-size KTM models, 85SX-105SX, MC85, TC85 and 2025-up 65SX class machines, is the taller end of gearing for the Austrian platform, and it is where hard enduro and cross-country riders spend most of their time. Running 46 to 48 teeth keeps revs manageable on long transfers and fast fire roads while still leaving enough torque multiplication for climbs. Coverage spans full-size KTM four-strokes and two-strokes in orange, red and black anodizing, shared Husqvarna, KTM and Gas Gas fitments in 47 and 48 teeth, mini-class KTM 85SX-105SX with Gas Gas MC85 and Husqvarna TC85 sprockets, and the newer 2025-up KTM 65SX, Gas Gas MC65 and Husqvarna TC65 pattern in 46, 47 and 48 tooth black. All are machined from hard-anodized aluminum so a large sprocket does not add rotating weight where it hurts acceleration and suspension action. Precisely cut teeth keep the chain fully seated, which reduces slap and helps guides and sliders last. A well-chosen ProTaper tooth count gives smoother power delivery and less clutch work.
