Designed for off-road use, this kit withstands the typical stresses of motocross: sharp accelerations, jumps, and abrasive terrain. The standard steel sprocket prioritises durability on hard surfaces and in demanding conditions. The rivet attachment ensures a strong connection, to be installed by a professional or with suitable tools.
Among the models for which this sprocket/sprocket ratio is commonly used: KTM 500 EXC-F SIX DAYS (2026), GAS GAS EC 500 F (2026), and KTM 500 EXC-F (2026). Be sure to check the alignment and length before installation and regularly monitor the tension and lubrication to maintain the longevity of the transmission.
