AR10C-OE – SPARK PLUG AR10C-OE (KTM OEM A40039093010)

THE SPARK PLUG

The BRISK AR10C-OE (OEM reference A40039093010) is the factory original equipment spark plug for:

• KTM 50SX
• GasGas MC50
• Husqvarna TC50

Following years of close cooperation with KTM, GASGAS and Husqvarna racing factory teams, BRISK has become the official spark plug supplier for 50cc and 65cc SX, MC and TC production models from 2024 onward.

Developed through joint engineering and extensive testing with KTM, the AR10C-OE was designed to guarantee reliable mixture ignition across the entire engine power range. With modern race-focused mini motocross engines delivering higher performance and improved reliability, this plug ensures consistent spark quality under all operating conditions.

DESIGN & PERFORMANCE

The AR10C-OE features a nickel alloy centre electrode filled with a copper core for excellent heat conductivity. This design optimises the thermal balance of the spark plug’s active components, maintaining stable ignition during cold starts, low-speed riding, and sustained high-load operation.

The copper core rapidly dissipates heat from the firing tip, reducing fouling and maintaining consistent combustion — essential for high-revving 50cc race engines.
