2015 Beta 390RS[edit]

2015 Beta 390RS

The 2015 MY Beta 390 RS sports a four-stroke, liquid-cooled, 386cc, single cylinder engine mated to a six-speed, manual transmission. It is one of the lightest dual-sports available on the market, thanks to the engine, frame and the suspension, which all are the same as the ones on the RR off-road bikes.

A light and agile dual-sport, the 390RS comes with an attractive pack of features, such as a Trail Tech Voyager GPS, RR-inspired graphics, an engine that's 2.2 lb lighter, tuck-away mirrors, off-road inspired D.O.T. tires, and softer seat foam.
