The KTM Duel-Sport or Adventure line is known for their incredible durability on long distance trips across every type of terrain known to man. With its full fairing body style, windshield, up-right seating position, good suspension travel, and luggage carrying capabilities, the Adventure line is great for both daily commuting and cross-country excursions. From smoothly paved road surfaces to rock climbing, the KTM Adventure will successfully take you there and back again while carrying you and all your luggage. 

Though common over-seas, the KTM Adventure did not hit the US market until 1997 with the 620 LC4 being the first one to be imported. It did not sell well, and with only a few being imported before it was discontinued in 1998, the 620 LC4 is a very rare find. 

In 1999, KTM imported the 640 Adventure. It was considerably more popular than the 620 which led to KTM selling them until 2007 when it was replaced by the larger 990 model.

Many KTM engines are designated LC4 which means liquid-cooled, 4-stroke engine. The 950 and 990 Adventure models however have a specially designed LC8 engine. KTM took a pair of cylinders from their LC4 motors and combined them onto a specially modified crankcase to create the new LC8 motor. It put out some really nice horse power with the 2003 model claiming 102 BHP at 8,000 RPM.
