TECHNICAL SPECIFICATIONS The pinions are made from aluminium with hard oxidisation 25 microns deep.With this treatment Malossi has maintained a particularly light shape of the piece whilst guaranteeing high wearresistance.The central hub is made from a special steel alloy, not heat treated in order to avoid making it too hard and thuscausing friction problems with the motor transmission shaft.The following tooth options are proposed z.: 24. 27. 28. 29.
