This JT Sprockets sprocket is aimed at motocross riders and roadster owners looking for a robust part that meets manufacturer specifications. By changing the front sprocket, you modify the gear ratio: reducing teeth increases stretch and speed, while increasing teeth favors acceleration and torque responsiveness. Check compatibility with your chain and tension before installation.

Examples of compatible models: KTM 690 SMC R (2026), Husqvarna Norden 901 Expedition (2025), CF Moto 800 NK Sport (2025). For reliable transmission, always pair sprocket, rear sprocket, and chain appropriately and regularly check for wear.
