2012 Beta 520RS Review

American Beta is releasing the 2012 Beta Dual Sport RS model line up with a complete range being offered for 2012 including 350, 450, and 520 versions.

The RS model range has been designed for the USA market with all three models being 50-state street legal. These premium dual sporters include our famous twin cam 4 stroke powerplant that incorporates a heavier flywheel for chugging power to tackle the tough stuff while the twin cam and short stroke allows amazing over-rev for the faster-paced conditions.

Newly added to the range for 2012 is the Beta 350 RS. A bike designed for single track trails as well as all-around casual riding. The 350's engine provides enough power and torque for both the casual play rider as well as the serious dual sporter. With its titanium valves and twin-cam engine the 350 RS offers a level of performance that will exceed riders expectations.

Returning for 2012 are the popular 450 and 520 versions. All receiving the same engine upgrades as our popular RR models. These two models have been sold out in recent years as more riders are discovering the beauty of Beta.

BYOB (Build Your Own Beta) is back for 2012! Customers can build their own Beta online by adding suspension settings as well as the accessories he or she desires. Their new Beta will arrive at the closest dealership or a dealer of their choice with all the items installed including a nameplate of whom the bike was built for.

The American Beta team has released three new models namely the 350, 450, and 520. The Beta 350 RS was especially developed to deal great with dirty race tracks but also with casual riding.

The motorcycle sports a single cylinder, 4‐valve, 4‐stroke liquid cooled engine with a displacement of 349 cc. The engine is mated on a six speed transmission and features electric start with back up kick starter.

When it has to deal with difficult terrains the BETA 350 RS is helped by its rugged suspensions which are able to keep the wheels in check and to offer a proper ride quality. The front wheel features a 45mm Marzocchi fork with compression and rebound damping adjustments for Dual Sport use while the rear wheels received an adjustable Sachs shock absorber.

For the Beta 350 RS is available the Beta BYOB (Build Your Own Beta) program. This program allows you to build your own Beta online by adding several suspension settings or various accessories.
