Short Description
BRISK Factory Iridium Racing spark plug developed for new-generation KTM, Husqvarna and GasGas 50cc and 65cc motocross models. Features an iridium center electrode, reinforced ground electrode and racing-focused design for reliable ignition and improved performance.
Product Description
BRISK Factory Iridium Racing Spark Plug
The BRISK Factory Iridium Spark Plug is a high-performance racing spark plug developed specifically for the latest generation KTM, Husqvarna and GasGas mini motocross motorcycles.
Developed through cooperation and testing with KTM Group racing applications, this spark plug is designed to provide reliable ignition throughout the engine's operating range, even under demanding motocross conditions.
The optimized iridium center electrode requires lower ignition voltage while helping provide a strong and consistent spark. Its reinforced ground electrode and specialized design improve access of the air/fuel mixture to the spark area for efficient combustion.
Compared with conventional spark plugs, the iridium electrode also provides excellent resistance to heat and electrode wear.

Why Use the Factory Iridium Spark Plug?
The iridium center electrode provides excellent durability and maintains a consistent spark gap even under high operating temperatures.
The optimized electrode geometry also helps reduce the voltage required to generate a spark, which can improve ignition reliability during difficult starting conditions or when the engine is operating under high load.
Its racing-oriented construction makes it particularly suitable for demanding motocross applications.
Important Fitment Note
Please check your motorcycle model, production year and existing spark plug before ordering.
