Vehicle Information
KTM 620 EXC Motorcycle - Dual-Sport (1994-1998)
The KTM 620 EXC, produced from 1994 to 1998, is a robust single-cylinder enduro motorcycle within the renowned LC4 family. Powered by a liquid-cooled, SOHC, 4-valve engine, its displacement was typically 608 cc or 609 cc, despite the "620" designation. These models delivered strong performance, with horsepower generally ranging from 50 HP to 55 HP, making them popular for off-road and competitive riding. The 620 EXC was a primary enduro model, often appearing as "620 LC4 EXC" or "620 LC4 E/XC" during these years. While the core 620 LC4 enduro engine maintained consistent displacement for off-road models during this period, the LC4 platform itself saw continuous evolution. Minor improvements, such as transmission gear spacing, were introduced in models like the 1996 KTM 620 Adventure. A notable generational shift occurred in the street-oriented Duke line, with the 620 Duke (609cc) produced until 1997, followed by the 640cc Duke II in 1998. This indicates an evolving platform rather than a major engine redesign for the 620 EXC. Q: Will this part fit my specific KTM 620 EXC model?
