Siggs Hub Overhaul (Grooved Ball Bearing) Front Wheel | Piaggio SI

With the Siggnature bearing conversion kit for the front cast wheel of the Piaggio Si, you get a front wheel hub that has been completely engineered from the ground up with modern bearing technology—precise, durable, and designed for reliable performance. This isn’t just a partial repair—it’s honest, high-quality workshop work featuring a meticulously executed bearing conversion.

This offer is aimed at anyone who wants to perform a technical overhaul on their Piaggio Si or who, as part of a rebuild, wants to ensure long-term, reliable front-wheel bearings. Especially on the front axle, smooth operation, clean bearings, and precise steering are crucial for riding stability and safety.

At the heart of the conversion is the professional replacement of the original bearings with new, compatible, high-quality industrial deep-groove ball bearings. The bearing seats are inspected and prepared, necessary adjustments are made professionally, and the new bearings are precisely positioned and cleanly installed. This results in play-free, smooth operation with significantly improved durability compared to the original design. In addition, all other relevant components are replaced with precisely matching new parts.

Furthermore, as part of the overhaul, properly matched brake shoes are installed to ensure consistent, easily modulated, and reliable braking performance. After the bearing overhaul, the front wheel hub delivers smooth operation, precise function, and clean brake response.

This bearing overhaul creates a technically sound, durable foundation for safe handling and worry-free operation of the Piaggio Si.
