Overview

Beta RR 350 Enduro

The Beta RR Enduro models have become well known for their immediate and genuine approach, for reliability, long maintenance intervals and, last but not least their 100% Italian style. Today, the third generation RR4T models are equipped with our own engine made in Rignano Sull’Arno and arrive on the market as the result of a continuous development for many different riding abilities. Many are the refinements and innovations, both on the frame and the engine, all designed to increase reliability and riding feeling. A wide range of displacements are now available, strengthened by the new 350cc engine, a first for Beta in the enduro market. For 2012 Beta has developed a complete range of enduro bikes to appeal to both the weekend hobbyist as well as the seasoned Pro. American Beta is proud to announce the 2012 Beta Off Road RR model line up with a complete range being offered for 2012 including 350, 400, 450, and 498 versions. (498 RR formerly known as 520 RR) Beginning with the 350RR, Beta feels this is the ultimate single-track motorcycle as its ability to change direction is unmatched while still offering enough torque and power for both play riders and racers. The 350 provides a "2-stroke feel" yet still offers the traction and smooth power delivery of a 4 stroke. Returning for 2012 are the proven 400, 450, and 498 RR models that have helped put Beta on the off road map. These models continue to impress the magazines as well as the riders that own them.
