The American BETA 2012 dual sport 450 RS has been designed for the U.S. market, making them street legal as well as capable of handling some extreme off-road riding. Most dual sport motorcycles are designed with an emphasis on riding city streets with the occasional light trail riding however this is not what the BETA was designed for. It is more than capable of entering a competitive enduro competition and taking all the other bikes to school.
The single cylinder, four-valve, four stroke, 450cc engine in the 2012 BETA 450 RS has more than enough power and strength to take you over mountain tops, rugged roads and as well as riding the city streets in comfort like a roadster. The engine has a redesigned cylinder head to reduce engine noise and increase reliability. This was accomplished by reinforcing the camshaft bridge, vale retainers and cam chain tensioner. The clutch is a smooth shifting and durable component with its upgraded primary gear and springs, letting you shift in higher stress conditions without missing a gear. The redesigned engine uses a six-speed manual transmission that handles high temperatures, extreme shifting stress and high torque very well, making it reliable both on and off-road. The Keihin carburetor is efficient at providing the proper amount of fuel to the engine without flooding it.
The suspension on the 2012 BETA 450 RS is a premium system with a Marzocchi inverted fork in the front and a twin sided swing arm with a single Sachs shock absorber in the rear. The plentiful amount of travel at both ends ensures that this bike can handle the most extreme of off-road terrains. In addition to the cushion the suspension provides for off-road riding, it is still a dual sport set up making it very comfortable to ride on the road.
