Ultra-light valves have extremely thin valve stems on par with those found in supersport machines; intake valves feature thick heads for increased strength.

Haven't we been through this air fork "thing" before?

That Kaw has a form of traction control.

The thinner the valves that faster the will fail and cause more entertainment for us  :P

Might as well put "Harley Davidson" badges on the tank, and make it official.

"Pneumatic Spring Fork (PSF) eliminates the main fork springs by using compressed air as a spring." 

My 1976 YZ had air forks without any spring, now Kawasaki does  :o

Some of the early 90's Maicos had a Muller airfork.

Back in the old days most air suspension systems went to a dual chamber,dual air pressure system in an effort to get around the rapid rate rise of an air system.
