Frequently Asked Questions
Q: Is this sprocket made from aluminum or steel?
A: This RFX front countershaft sprocket is constructed from high-tensile, case-hardened alloy steel, making it drastically more resistant to wear than aluminum alternatives.
Q: Will this sprocket fit older 50cc models prior to 2024?
A: No. This sprocket is explicitly engineered to fit the completely updated drivetrain tolerances found on the 2024 and newer generation KTM, Husqvarna, and GasGas 50cc models.
Expert Pro-Tip: Front sprockets take the brunt of drivetrain wear because the chain must wrap around a much tighter radius than the rear sprocket. To maximize the lifespan of your new sprocket and protect your engine's countershaft seals, always inspect your chain tension frequently and swap out your drive chain if it shows signs of stretching or stiff links.
