The RFX Pro front sprocket with 13 teeth is designed for motocross and enduro riders who want a robust and reliable part for their transmission. CNC machined from high-strength steel and then carburized to achieve a high Rockwell hardness (ā60), it offers excellent wear resistance without unverified technical claims. Its "mud-proof" version features drainage grooves on both sides that limit dirt accumulation and facilitate a clean connection between the chain and sprocket.
Main compatibilities: HONDA CRF 250 X (ME11) 2019, HM CRE-F 250 R 2014, HONDA CRF 250 R (ME10) 2017. Mounted on a 520 chain, this sprocket is ideal for muddy training sessions and special stages where longevity and cleanliness of the transmission matter.
