Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Coolant Type:
Not applicable (air-cooled engine).
Desmodromic Valve Adjustment:
Requires specialized knowledge and tools; improper adjustment can lead to engine damage. Parts catalog lists shims and adjustment components.
Electrical Gremlins:
Older Ducati models can be prone to wiring issues; correct parts are essential. Parts catalog helps identify correct harness components.
Carburetor Tuning:
Dell'Orto carburetors require periodic cleaning and adjustment for optimal performance. Parts catalog lists jetting and internal components.
Clutch Wear:
Clutch plates may require replacement over time. Parts catalog lists clutch plates, springs, and basket components.
Marque Origin:
Italy, founded in 1926 by Antonio Ducati.
Pantah Lineage:
The Pantah was a groundbreaking model for Ducati, introducing the 90-degree L-twin engine with desmodromic valves as a more accessible and modern platform compared to their bevel-drive twins. It served as the foundation for many subsequent Ducati models.
Pantah Variants:
Evolved into models like the 600TL, 650SL, and eventually the larger Pantah-derived bikes.
Production Period:
Late 1970s to early 1980s (approx. 1979-1983 for the 500SL)
Manufacturing Location:
Bologna, Italy
Motorcycle Journal Reviews:
The Pantah series was generally well-received for its performance and innovative L-twin engine, often praised for its character and handling by contemporary motorcycle publications. (Specific awards for the 500SL are uncommon to find documented as such, but the model series was a critical success for Ducati).
Vintage Motorcycle Value:
Highly regarded as a classic Ducati, representing a significant step in the brand's technical development and a precursor to modern Ducati sportbikes.
