Reinforced auxiliary shaft axle for Vespa PX125, PX150, PX200, Cosa and T5 125 as well as corresponding LML and Motovespa models.
The BENELLI reinforced auxiliary shaft axle is the resilient solution for largeframe engines when the primary drive not only needs to be repaired close to series production, but also needs to be built up cleanly for higher loads. The thicker shaft in conjunction with specific thin auxiliary shaft needles results in a significantly more robust design than with simple standard axles.
This version works with a thicker axle shaft and specific thin needles to match. It is precisely this combination that makes the axle interesting for heavy-duty large-frame transmissions, because the highly stressed area of the bearing surface is designed to be more robust.
The auxiliary shaft axle has a bearing surface on which the needles of the primary bearing on the alternator side run. While the needles themselves wear surprisingly rarely, the raceway of the axle often shows the first signs of damage during overhauls.
The complete factory list is extensive. For practical purposes, a summary by model group makes more sense.

The BENELLI reinforced auxiliary shaft axle is a very good choice for large-frame engines if the focus is on load capacity and clean repair of the primary drive. The reinforced design, the high-quality material and the clear recommendation for more powerful engines make it a real must-have for sporty and tuned setups.
