Brand Focus:
Ducati's legacy in V-twin performance and racing
Pantah Series:
The Pantah series represented a significant shift for Ducati, introducing the now-iconic 90-degree V-twin in a more compact and accessible package.
Development:
Designed by Fabio Taglioni, aiming to provide Ducati performance in a more modern and user-friendly motorcycle.
Production Years:
Introduced in 1980, 500SL models produced from 1981 onwards
Manufacturing Location:
Bologna, Italy
Motorsport Heritage:
Ducati's success in racing, though the Pantah itself was primarily a road-going model, it laid the groundwork for future racing platforms.
Contemporary Reviews:
Praised for its handling, V-twin character, and braking performance; often noted for its relatively compact size and lighter weight compared to larger twins.
