0.7 mm
I have a 07 KTM 525 XCW and the manual call for 6mm on plug gap.
0.60mm
Impossible to answer, depends on what model KTM you have.
NGK Spark Plug BR8ECM
NGK BR8HS with a .032" (0.8mm) gap
You didn't specify what size but most dirt bikes will run a gap of 0.5-0.6 mm.
NGK CR8EK or NGK CR8EiX (Iridium)
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.
NGK BR8ECM Standard with a 0.024 gap
NGK CR9EKB 05 NGK CR9EKB 05
If you just bored it once or twice over, your stock spark plug will be all you need. A NGK BR10ECM (or corresponding plug from another brand) with a .032" (0.8mm) gap.
