Light, compact and sleek, the Beta 390 RS is an exciting dirt bike built for those who love to venture on unpaved roads.

This potent dual sport bike is propelled by a Beta-built single cylinder, 4 valve, 4 stroke, liquid cooled engine with electric start with back up kick starter. Its power is transferred to the ground by means of a six speed transmission with wet multi-disc clutch.

The motorcycle’s backbone is represented by a molybdenum steel frame which sits on a 48 mm Sachs USD fork (with adjustable compression and rebound) and a rear aluminum body Sachs shock absorber (adjustable rebound and hi/low speed compression).

Other features that are worthy of being mentioned include Voyager GPS unit, handlebar pad from Race Edition, new design seat foam and new graphics and color scheme based from the RR models.
