The 2012 MY Beta 400RR is motivated by a four-stroke, liquid-cooled, 398cc engine paired to a 6-speed manual transmission, designed to deliver a full-on, thrilling experience around any off-road course. With a new primary gear and new springs fitted for better clutch action and gear engagement, the 400RR can better channel all the grunt from the engine to the track.
The frame has extra gussets and an increased tube diameter on the lower tubes, for more structural rigidity. These improvements make the frame flex less and improve the overall stability of the enduro bike under hard riding conditions.
