These CNC machined wheel axles, by G-PRO, are milled from a solid block of a very stable aluminium alloy. This CNC procedure and fine balancing of the axle with a smoothly running bearing provides a noticeably easier rotation when compared to the original item. The reduction in weight by over 30% supplied by the inclusion of the milled item also adds to a freer and lighter operation and a welcome reduction of the total unsprung weight of the suspension.
This wheel axle/centre is compatible with all PIAGGIO steering columns (e.g. the Vespa ET/LX/LXV/S/Primaver/Sprint) with a brake disc with 97mm circumference of five mounting points, along with wheels with five mounting points. Especially for newer Primavera/Sprint models it´s possible to mount the ABS-wheel due to the five mounting points.
SIP-TIP: Due to the lack of a cog drive for the original speedometer an electronic speedometer with a KOSO/SIP speed sensor should be included to indicate your road speed. To complement the new CNC machined wheel axle why not also add titanium bolts for the brake disc and wheel?
