Siggs Hub Overhaul (Tapered Bearing) Front Wheel | Piaggio SI

With the Siggnature hub overhaul for the Piaggio Si’s front cast wheel, you’ll receive a front wheel hub that has been completely technically overhauled to its original specifications—precise, durable, and designed for reliable performance. This isn’t a partial repair, but rather high-quality, professional workshop work carried out with all-new components.

This offer is aimed at anyone who wants to restore their Piaggio Si true to the original or who, as part of a restoration, specifically wants to retain the classic wheel bearing assembly. Especially for original vehicles, a thoroughly overhauled stock bearing assembly is crucial for an authentic riding experience and reliable performance.

At the heart of the overhaul is the complete rebuild of the original wheel bearing assembly for an entire wheel axle, including cones, ball bearings, and new brake pads. All components are precisely fitted, carefully adjusted, and professionally installed. This results in a smoothly running, play-free bearing assembly that corresponds to the original yet is technically up to date. In addition, all other relevant components are replaced with precisely matching new parts.

Furthermore, matching brake shoes are installed during every hub overhaul to ensure consistent, easily modulated, and reliable braking performance. After the overhaul, the front wheel hub delivers smooth operation, precise function, and responsive braking.

This original hub overhaul creates a technically sound, durable foundation for authentic riding performance and worry-free use of the Piaggio Si.
