 This is a replacement Motonica 20 Tooth Rear Pulley, and is intended for use with the Motonica P8.0R. This pulley is also an optional part for the P81, to complete the 20T/48T/18T/26T internal gear ratio modification that is recommended for small, tight tracks.
NOTE: This modification requires the 48 Tooth pulley (MOT12007), rear belt (MOT06007), and 26 Tooth side pulley (MOT12006) to complete the conversion. Additionally, two Middle Layshaft Mount spacers (MOT15123RD05) are required to raise the mount, allowing the belt to rotate more freely.
