The complete PX Lusso drive shaft gear kit includes 4 gear cogs with 57, 42, 38 and 35 cog teeth respectively, a gear selector cruciform, a selector rod and the relevant spacers and circlips. This kit saves ordering all the parts you need separately to overhaul your drive shaft assembly. The kits are available in 3 versions: the high end package as a mix of PIAGGIO and DRT parts, the high-quality one from RMS and a budget version. The existing input shaft is 100% compatible and does not have to be replaced or modified.
The drive shaft produced by RMS/PIAGGIO has the grooves that help hold the cruciform in position during engine use, typical of the original PX Lusso drive shaft design along with the relevant spacers and circlips. Good for tuned engines and perfect enigne work.
The Eco design does not include the Lusso grooves and is therefore more suited to the more moderately tuned scooters (under 15 PS). This kit also lends itself ideally to untuned, economic standard engine rebuilds.
Conclusion: One stop shop answer for large frame motor gear boxes.
SIP-TIP: Do not forget to order a new PX Lusso selector box if necessary for your rebuild, a suitable rear wheel holding nut and gear box oil. New engines shaft oil seals, bearings and a gasket set are essential with every major gearbox rebuild.
