The KTM 300 GS Enduro Sport is a testament to the brand’s pioneering spirit and innovative approach to off-road competition. Born from the lessons learned from the 250 cc Penton Hare Scrambler and other air-cooled 2-stroke enduros, this water-cooled behemoth was engineered to dominate the open class in the International Six Days Enduro (ISDE) series.
Its 273 cc engine, essentially a bored-out 250, packs a punch that’s hard to ignore. With its robust power delivery and snappy throttle response, the 300 GS Enduro Sport is an absolute blast to ride, devouring challenging terrain with ease.
From its inception in 1986 to its eventual discontinuation in 1987, the 300 GS Enduro Sport left an indelible mark on the world of off-road competition, cementing KTM’s reputation as a manufacturer of uncompromising excellence.
