The KTM 300 is a series of 2-stroke enduro off-road motorcycles made by KTM. They are the Penton-inspired 1984 300 GS, the 300 DMX, the dirt only 300 MXC, European road legal 300 EXC and their current US counterparts the 300 XC (close-ratio) and 300 XC-W (wide-ratio gear box) respectively. The KTM 300 is designed for difficult off-road conditions. The 300 EXC and the 300 XC-W have a small headlight, speedometer, tail-light and somewhat softer linkless PDS suspension. Starting in 2008 all 300's came with electric start.
The original 300GS Enduro grew out of the experience with 250 cc Penton Hare Scrambler and other KTM air cooled 2-stroke enduro bikes. Since the 1986 rules for the International Six Days Enduro (ISDE) for the open class allowed any bike larger that 250 cc, KTM started work on a water cooled over-250 cc bike for the open class. They essentially bored their 250 out to 273 cc and called it a 300. This version of the 300 was discontinued in 1987. KTM also tried sleeving down their 500 cc two-stroke to 350 cc calling it the 350GS, but the left side kick-starter and the right side chain were not popular.
In 1990 KTM got serious and the present-day 300 was born. Dubbed the 300 EX/C it's engine delivered very smooth power and did not produce a power hit. At low RPMs the bike could go almost anywhere. In the mid-range and the top-end the smooth power delivery allowed the rider control over a wide variety riding conditiond from tight trails to wide open stretches. The plush suspension worked well compared to the older GS models.
The bike was also offered as the 300 DMX, a California desert version. These early KTM motors had 297 cc displacement with 72 mm x 73 mm bore/stroke. Still the 300 hadn't reached its full potential. Ignition and jetting problems plagued these early models. In 1992 the company suffered financial woes and development was slowed. The 1993 KTMs had Öhlins USD forks. In 1993 Motoplat went out of business, forcing KTM to switch to SEM ignition systems. The 1996 model had Marzocchi USD forks and an Öhlins shock, a chrome exhaust pipe and silencer, a motor with better performance, increased cooling and stock Boysen reeds. For 1996–97 the bike was offered in a 360 cc version. In 1997 KTM switched to Kokusan ignition systems.
