Three person express
The ULTRA 310X is the “Standard” model of the Series – if any model with a 300 PS output can be called “standard.” With its fantastic supercharged engine, nimble hull, great flagship features and a comfortable two-piece seat that accommodates three passengers, the ULTRA 310X sets the bar for standard commendably high.
