Manufacturer part number: 307--520-13P
The RENTHAL standard steel sprocket 307 - 520 is designed for motocross riders who demand reliability and precision on the track. Carefully machined from nickel-chrome-molybdenum alloy steel, it offers good wear resistance while remaining lighter than many OEM parts. Its 13-tooth design with a 520 pitch easily integrates into common transmissions and effectively transmits power to the rear wheel without excessive compromise on longevity.
Renthal, a recognized brand in competition, offers a sprocket that minimizes friction through precise machining while providing an excellent balance between efficiency and durability. Ideal for replacing a worn sprocket or fine-tuning the gearing on the track.
Common compatibilities: HUSQVARNA CR 125 (2014), KTM 65 SX (2011), HUSQVARNA WR 125 (2013). Check the pitch and tooth count before installation to ensure compatibility with your transmission.
