Yes, it is.
You can buy an M10x1.0mm to 1/8" NPT adapter at McMaster.com. Or there is also a website that sells shock breeders, do not remember their name, they sell KTM and other adapters as well.
I used a vacuum brake bleeder tool hand pump to bleed the shock on my MX after a revalve. Worked for me as well as a $2K+ WP shock bleeder.
