2014 Open-Class Dual-Sport Smackdown: Beta 520 RS vs. KTM 500 EXC

The Beta’s 520 RS model designation is a misnomer, as its short-stroke, four-valve Single checks in at just under 500cc. After sourcing KTM’s SOHC engine for years, Beta switched to dual overhead cams for its in-house engine because its engineers feel that the dual bumpsticks provide more precise valve timing.
