These tanks are a high-quality reproduction of the original Harley-Davidson 750 cc tanks from 1940 to 1946 for Solo and Servi-Car models. Visually and functionally, they closely follow the historic original – ideal for authentic restorations or period-style custom projects.
The tanks feature all original-style details:
- Mounting points for the shift gate
- Fitting for the fuel valve with operating shaft running through the tank
- Cut-out for speedometer and matching base plate
All gas tanks by W&W Cycles are delivered unpainted and unsealed. Before the paint job and final installation please consider the following:
- We consistently receive tight gas tanks from the manufacturers, both Custom and OEM replacements.
- Problems mostly occur during or after installation. Hence, before a pressure test and before painting - a probationary tensionless installation is highly recommended. Any leverage on the tank mounts spells trouble. Better use our selection of small parts.
- To avoid corrosion always fill your tank to the max during longer downtimes or seal it on the inside.
