Founded in 1978 as a division of the massive Hyosung Group, Hyosung Motors & Machinery Inc. began
producing motorcycle designs under license for the South Korean market in 1979. In 1986, Hyosung
established its own research and development centre in Japan and, the following year, began mass
production of its own designs. Hyosung was the offi cial motorcycle supplier for the 1988 Summer Olympics
in Seoul.
In 2003 Hyosung Motors & Machinery Inc. was spun off from the Hyosung Group, and remained its own
corporate entity until it was recently absorbed into one of the biggest companies in South Korea – S&T
Corporation.
Accordingly, Hyosung Motors & Machinery Inc. has now been renamed as S&T Motors Co. Ltd, but the
Hyosung brand name remains unchanged.
S&T Motors Co. Ltd’s goal is simple: to become one of the major players in the global motorcycle industry.
The massive company is committed to strengthening its international competitiveness through a vigorous
research and development process.
In just 20 years, Hyosung has made a highly successful transition from producing simple, effi cient bikes
for commuting into the highly competitive recreational market. It’s also expanded into developed export
markets such as Australia, Europe, America, Brazil and China.

Roadtrip Australia

Three Indians. Two bikes. One van. 20,673km. 72 days. That was the equation as an intrepid bunch of Indian
youths joined forces with a pair of Hyosung GT650Ss for The Great Australian Road Trip (TGART) in late 2007
and early 2008. The team travelled anti-clockwise around Australia, with the Hyosungs performing faultlessly
in all conditions: from the cooler climes of southern Australian to the harsh extremes of the north.

There are plenty of 250s on the market, but the majority are undersized and underpowered. Not the GT250R.
It has the same dimensions as its 650cc sibling, so it feels like a full size sports bike, and it’s all wrapped in a slick
aerodynamic fairing with racy clip-on handlebars.
The GT250R has additional features that are simply not available on many of its challengers. Twin 300mm semi-
fl oating front discs, massive 41mm upside-down forks and digital Instrumentation all combined with programmable
EFI for an unmatched performance edge in its class. Get serious about your riding from day one.
