Sunstar 12 Tooth 520 Chain Front Sprocket for 2025 Husqvarna TC250 Heritage 35712

If you're running a 2025 Husqvarna TC250 Heritage, the front sprocket is your direct link to power delivery and acceleration response. A worn or undersized sprocket robs you of torque when you need it most, while the right 12-tooth setup gives you the bite to launch hard and carry speed through technical sections. This Sunstar countershaft sprocket delivers the strength and precision to handle sustained abuse without degradation.

Built from case-hardened chromoly steel with a Parkerizing finish, this sprocket resists corrosion while maintaining the rigidity required for aggressive riding. Every tooth is precision-engineered to mesh cleanly with your 520 chain, eliminating slack and noise while maximizing power transfer. At under a pound, you get robust durability without unnecessary weight penalty.
