Due to the use of hard steel, the wear on JT's sprocket is less than on the original KTM sprocket, according to the manufacturer. Developed for the KTM Duke 125, the standard 14 tooth sprocket is designed for the KTM Duke 125, but it is possible to change the gear ratio of the bike if you use other sprockets also available in our shop. The two inner diameters are 16 mm and 20 mm, the hole spacing is 34 mm and the width 7.1 mm.
Inner diameter 1: 16mm
Inner diameter 2: 20mm
hole spacing: 34mm
When using a 15 tooth sprocket, the splash guard plate on the motor, under the sprocket, must be removed.
