If not, the short oldie gear is not able to turn the power into speed. With the DRT 62 teeth extremely tall transmission are possible for all 80-200cc models. The strong setups of the current engines mean these transmissions are necessary. Note: On both of the primary drive cogs a large 115/108mm PX200 clutch, the appropriate straight-toothed DRT clutch gear cog and the primary repair kit 16069400 are all necessary. The PX 200 primary drive repair kit will require its outer diameter to be decreased. In combination with the original Vespa GS 150 models clutch, the clutch cog should be solidly riveted to the original, straight base-plate.### (for the purpose of comparison)
