The 2015 MY Beta 390RR sports an all-new, four-stroke, liquid-cooled, 386cc single cylinder engine and a six-speed manual transmission. The engine case is die-cast, reducing engine weight by 2.2 lbs. This weight reduction can be felt in the overall performance of the machine and is made possible thanks to a new crankshaft, connecting rod, cylinder head and piston.
The aesthetics have been revised, keeping the classic Beta red and white but with new graphics and a different color combination, giving the 390RR a fresh, edgy look.
