Vortex 420 Front Sprocket Honda Grom 125 

Vortex Steel Front Sprockets are well known in the motorcycle world for being tough, attractive and competitive. On the surface they feature a dazzling zinc coating and weight reducing holes. Beneath the surface they feature precision machined and induction hardened steel. Unlike heat treated steel, the process of induction hardening heats the steel using a controlled electrical current. This method allows Vortex to manufacturer a quality sprocket with extremely tight tolerances. 

Features:

• Stock chain pitch: 420
• Induction hardened steel
• Offers improved concentricity which provides a stronger, quieter and longer-lasting sprocket
• Drilled for weight savings
• Corrosion-resistant plating
