Vehicle Information
KTM 250 EGS Dirt Bike (1990-1999)
The KTM 250 EGS, part of KTM's renowned 250cc enduro and motocross lineup, was a prominent two-stroke off-road motorcycle produced from 1990 to 1999. Throughout this decade, the EGS, alongside its EXC, MXC, and SX siblings, featured a liquid-cooled, 249cc single-cylinder engine. Positioned for enduro riding, the EGS often balanced performance with market-specific restrictions, while other trims like the EXC and SX targeted more aggressive competition. The 1990s saw continuous evolution for the KTM 250 platform. A "completely new" enduro bike was introduced in 1990. Significant chassis overhauls occurred in 1993 with a "modern chassis architecture" and again in 1995 with a new chromoly steel frame. Engine and component updates included a new Kokusan ignition in 1997, and a radical redesign for MX models in 1998 featuring the PDS suspension and a new cylinder. The hydraulic clutch was introduced in 1999. These changes reflect KTM's commitment to innovation in off-road performance. Q: How do I know which parts fit my specific KTM 250 EGS?
A: To ensure perfect compatibility, please use the year and edition selector at the top of this page. This will filter parts specifically for your motorcycle. Q: Are there significant differences between the EGS and other 250cc KTM models from this era?
A: Yes, while sharing the same engine displacement, models like the EXC, MXC, and SX often featured different states of tune, suspension setups, and components tailored for specific riding disciplines (enduro, motocross, cross-country). Always refer to your specific model and year.
Maintenance
| Component | Interval | Details |
| Transmission Oil and Oil Filter | Recreational Riding: Every 10 to 15 hours. Aggressive/Race-Level Riding: Every 5 to 10 hours. | For two-stroke models, engine oil refers to transmission oil. The oil filter should be replaced with each oil change. |
| Air Filter | Recreational Riding: Every 10 to 15 hours. Aggressive/Race-Level Riding: Every 5 hours. | Regular cleaning and re-oiling of the air filter is essential, especially in dusty or muddy conditions. |
| Spark Plug | Inspect regularly and replace as needed. | Regular inspection is crucial for efficient combustion. For late 90s models, replacement is part of routine maintenance. |
| Coolant | Every 1 to 2 years or every 40 to 50 hours. | Regularly inspect hoses and level. Use a 40% antifreeze / 60% distilled water mixture, compatible with aluminum components. |
These intervals are general guidelines. Actual needs may vary based on riding style and conditions. Always consult the official owner's manual for your specific model and year for precise information.
