Tops Speed

The New 2012 Beta RR just got back in from a great day of riding the new 350 Beta. It left me with a very favorable impression on the Italian manufacturer’s 2012 line up. The 350RR has some distinct handling traits that make it a hoot to ride. The smaller motor makes power in a way that is fun and rewarding. In short, I found the littlest Beta a great trail companion.

The 2012 Beta 350 RR receives an array of updates and refinements less than a year after the first 2011 350 RR units arrived in the U.S. Changes to the Beta-designed engine (KTM mills were used prior to 2010) include a redesigned head that incorporated a stiffened camshaft bridge, new valve retainers and a quieter cam chain tensioner. A new clutch primary The 350 RR received a host of internal engine refinements and a new Brembo clutch master cylinder.gear and springs are mated with a new Brembo hydraulic clutch master cylinder, plus the oil volume has been increased to protect internals better.

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.
