ProTaper – ProTaper Front Sprockets - KTM / Husqvarna / GasGas, including 10, 11, 12, 13, 14 and 15 tooth countershaft sprockets for KTM, Husqvarna and GasGas models, reaches from 50cc youth bikes all the way to full-size four-strokes, which is exactly what the shared Austrian platform demands. Small-bore machines run tiny countershaft sprockets, so the 10 and 11 tooth KTM front sprocket sizes matter enormously here: a single tooth on a mini changes gearing dramatically and can be the difference between a bike that bogs in deep sand and one that drives cleanly. Full-size KTM/Husqvarna fitments in 12 through 15 teeth suit everything from tight woods gearing to open-desert cruising, and cross-brand coverage means Husqvarna and GasGas riders use the same well-proven patterns. Hardened steel construction with accurately cut tooth flanks keeps the chain seated under hard acceleration and resists the hooking that shows up first on small sprockets because each tooth carries more of the load. Fitting the right ProTaper countershaft sprocket sharpens throttle feel, reduces chain slap, and keeps your gearing honest as the season wears on.
