Vehicle Information
KTM 125 EGS Dirt Bike (1992-1999)
The KTM 125 EGS, an iconic enduro motorcycle, was part of KTM's 125cc two-stroke off-road lineup from 1992 to 1999. Throughout this period, the EGS shared its fundamental engine platform with other 125cc models like the EXC (Enduro Cross/Competition) and SX (Motocross), though specific tuning and components might have varied to suit their intended disciplines. The 125 EGS was designed for general off-road riding and trail use. Significant changes occurred within KTM's 125cc lineup during these years. The engine displacement increased from 122.6 cc (1992-1996) to 124.8/125.0 ccm (1997-1999). A “new generation” 125cc engine was introduced around 1998, featuring a planetary gear-driven exhaust power valve system and a hydraulically activated clutch. Suspension improvements also took place, including the adoption of the PDS (Progressive Damping System) linkless rear suspension around 1998 and the replacement of Marzocchi forks with 50mm WP conventional forks on 125 SX models, a change likely extended to the EGS. The chassis was also improved in 1998 with new main frames constructed from high-strength chromoly tubing for a lighter, more rigid structure. FAQ:
