Vehicle Information
KTM 620 TXC Motorcycle - Street (1998)
The 1998 KTM 620 TXC is an off-road motorcycle, part of KTM's robust 620cc lineup. It is powered by a liquid-cooled, single-cylinder, four-stroke engine from the renowned LC4 platform. This 609 cc engine delivers approximately 55 horsepower (40.1 kW) at 7000 rpm, featuring a SOHC with 4 valves and a 5-speed transmission, designed for demanding terrain. While the LC4 engine platform saw various evolutions and displacement changes in other models over the years, the 609 cc engine was standard for all 1998 KTM 620 models, including the TXC. The closely related 620 RXC model, which shares many similarities, was produced from 1997 to 2001, indicating a consistent platform for this specific range. No significant mid-cycle generation or engine changes are noted for the 1998 620 TXC itself. Q: How can I confirm if a part fits my 1998 KTM 620 TXC?
A: To ensure perfect compatibility, please use the year and model selector on our product page. Q: Are parts for the 620 TXC interchangeable with other 620 models like the RXC or SX?
A: While some components may be similar, we strongly recommend using our year and model selector to verify fitment for your specific motorcycle.
