The 520RS was fitted with a 0.53 Gallon (2.00 Liters) fuel tank. The wheelbase was 58.11 inches (1476 mm) long.

2012 Beta 520RS[edit]

2012 Beta 520RS

The 2012 MY Beta 520RS has the biggest displacement in the RS family, and is the most powerful. Sporting a four-stroke, liquid-cooled, 497cc, single-cylinder engine paired to a sturdy six-speed manual transmission, the 520RS has all it needs to tackle both the urban streets and the muddy trails in the wilderness.

In this model, Beta increased the oil volume to the engine cam chain, reducing friction, and also made it easier to change the oil, thanks to a new oil drain plug. It features the BYOB (Build Your Own Beta) program, which allows one to choose from a wide variety of different accessories and settings. The BYOB version also comes with a nameplate of whom the bike was built for.

2013 Beta 520RS[edit]

In the 2013 MY Beta 520 RS, the Italian engineers improved the engine cam chain by introducing an increase in oil volume, therefore, reducing friction. Also, maintenance has become easier thanks to a new oil drain plug, facilitating oil changes.

The brakes have been fitted with new front and rear rotors, enhancing rider safety on the road but also improving performance off the road. The visual side has been upgraded with a new, stylish red color and a redesigned headlight and front fender support.

2014 Beta 520RS[edit]

The 2014 MY Beta 520 RS comes with a four-stroke, liquid-cooled, 497cc engine paired to a six-speed manual transmission. It has great off-road poise thanks to the frame and suspensions, derived from the successful RR beta series.

A new standard feature on the RS models, and in the whole Beta family is the Trial Tech Voyager GPS, which has downloadable maps, trip meters, clock and can show engine temperature. Plus, it allows the rider to organize, edit and share entire trail systems in 3D.

The fuel tank has been redesigned for a lowered center of gravity and to improve air flow from the radiators. With all these great improvements, the 2014 MY Beta 520 RS is a serious option to consider if one is on the market for a good dual sport.
