Product Description
Optimize your motorcycle's highway cruising efficiency and drivetrain longevity with the precision-engineered JT Sprockets Front Countershaft Drive Sprocket. As the world’s leading manufacturer of aftermarket sprockets, JT Sprockets constructs this 17-tooth drive sprocket using structural-grade SCM420 chromoly steel alloy to guarantee exceptional core toughness and absolute resistance against high-torque fatigue.
Every sprocket is engineered through advanced CNC machining and computer-designed tooth architecture to achieve exact fitment tolerances and an entirely true rotation. Fully induction heat-treated and finished via a specialized bead-blasting cycle, this sprocket features a hardened surface structure that reduces rolling friction and prevents early tooth hook wear, outlasting standard mild steel components by two to three times. The 17-tooth layout acts as an excellent choice for lowering highway cruising RPMs, smoothing out power delivery, and increasing top-end speed on long stretches of road.
- SCM420 Chromoly Steel Alloy: Forged from premium-grade structural steel alloy to withstand high-horsepower street and track conditions.
- Induction Hardened Teeth: Advanced thermal localized induction heat-treatment yields superior surface hardness to extend both sprocket and chain life.
- High-Speed Gearing Layout: The 17-Tooth architecture drops engine vibration and RPMs during high-speed commuting, improving fuel economy and rider comfort.
- Exact Spline Tolerances: Precision computer-cut interior splines provide a perfectly concentric, tight slide-on fit to protect your engine’s vital output shaft splines.
