You didn't specify what size but most dirt bikes will run a gap of 0.5-0.6 mm.

No, it's not true that the NGK BR9EIX spark plug is the same for both the KTM 85 SX and KTM 125 SX. While they may have similar spark plug specifications, the two bikes often require different spark plugs due to their varying engine sizes and performance characteristics. It's essential to consult the owner's manual or a professional to confirm the correct spark plug for each specific model.
I have a 07 KTM 525 XCW and the manual call for 6mm on plug gap.

The KTM 85 SX typically uses the NGK BR9ECM spark plug. It's important to check the owner's manual or consult with a dealer to confirm the correct spark plug for your specific model year, as specifications may vary slightly. Ensure to use the recommended gap and type for optimal performance.
