The 2010 MY Hyosung SF50R Rally has, at its heart, an air-cooled, two-stroke, 49cc, single cylinder lump paired to a continuously variable transmission, that can produce 5 horsepower and 4 Nm of torque.

Unlike its SF50B sibling, this machine has a more youthful, race-inspired visual appearance, with race decals and bold colors, and is sure to fit the taste of the more adventurous and young among riders. It comes standard with a dual seat, passenger grab rails, a front disc brake, and an under-storage compartment.
