Ethylene glycol-based coolant mixture (typically 50/50 with distilled water).
Desmo Valve Adjustment:
Requires specialized knowledge and tools; improper adjustment can cause significant engine damage.
Electrical Gremlins:
Older Ducati electrical systems can be prone to corrosion and loose connections; thorough inspection and cleaning are often necessary.
Carburetor Tuning:
Dell'Orto carburetors require precise setup and synchronisation for optimal performance.
Wear Items:
Clutch plates, fork seals, and wheel bearings are common wear items that may require replacement on higher-mileage examples.
Brand Origin:
Italy, founded 1926
Racing Legacy:
Rich heritage in Grand Prix racing, influencing road bike design.
Pantah Lineage:
The Pantah was a significant model for Ducati, introducing the 90-degree L-twin to a wider audience and evolving into models like the 500 SL.
Design Influence:
Styled by Pierluigi Premoli, it was one of Ducati's first modern sportbikes featuring a trellis frame.
Production Years:
The Pantah range was produced from the late 1970s through the 1980s, with the 500 SL being a specific iteration. The '1997' designation in the product name might be misleading if referring to a later model or a specific market release; however, the core design is from earlier decades. The manual likely covers this specific iteration or a broader range of the 500 SL Pantah.
