Product Description

The NGK 6205 (LKAR9BI9) is a Laser Iridium spark plug built for KTM's high-performance single- and twin-cylinder engines, matching the factory KTM 61239093200 part number used across the 1190 Adventure, 1190 RC8/RC8R, 1290 Super Duke R, and 690 Duke/Enduro R. Its precision laser-welded fine-wire iridium center electrode delivers strong spark energy for reliable ignition, well suited to the demands of a hard-revving motorcycle engine.

The platinum ground electrode is designed for even wear and extended service life, while the high-grade alumina silicate ceramic insulator reduces the risk of dielectric punch-through under sustained high-RPM operation. A wide operating heat range helps the plug resist fouling at low speeds while still avoiding pre-ignition under hard acceleration.

This is a strong OE-quality replacement for KTM owners doing a routine ignition service or addressing a misfire on one of the covered models. As a motorcycle-specific part, it's not intended for automotive use - confirm your specific KTM model and year against the list above, or cross-reference the OE part number, before ordering.
