Malossi HTQ Primary Gear Z 15/38 (Forced-Ø17) – manufacturer reference 6713339. Designed by MALOSSI for 50cc scooters, this primary gear is intended for gearboxes where the primary shaft is mounted in the cover of the case.
It offers a long first gear ratio of 15/38, suitable for Piaggio 50cc 2-stroke engines (models primarily produced from 1999 onwards). The fit of the assembly is tight: secondary transmission diameter of 17.77 mm, to be considered when replacing or adapting.
Examples of compatible scooters (for reference): VESPA SPRINT 50 2T (2016), PIAGGIO NRG 50 DT POWER (2015), HONDA NSC 50 VISION T2 (AF73) (2014). Before ordering, check the type of gearbox installed on your scooter (mounting of the input shaft in the cover or in the case) and the engagement diameter to ensure interchangeability.
Exact replacement part for exchanges on primary transmission: ideal for DIY enthusiasts and mechanics looking for an original MALOSSI gear matching the specified ratio.
