Look Ma', no springs

[gasgasman]

The '013 KXs have these new forks that are springless.You pump them up with air. Like the old Simmons forks.

I still have a custom two-part scaphoid courtesy of that exact bike. I hope Yamaha has set aside some money for the lawyers.

Most high end mnt bike suspension now uses air instead of spring.

Yeah, the 2013 CR450 has air forks and they stuck twin exhausts on it as well.

The new Honda CRF450R is fitted with new Kayaba PSF (Pneumatic Spring Fork, aka "air") forks. What's the advantage of air forks over traditional spring forks? Mainly less weight and easier adjustability. Since the springs are replaced by air, the forks are much lighter, at least two pounds, and there is also less unsprung weight. Changing "springs" is now as easy as using a bicycle pump. One pound is equivalent to one spring-rate level. Air forks aren't new but stiction has always been a problem with air forks due to tighter seals on the fork tubes themselves, but with today's new anti-stiction, fork-coating technology, the advantages of air forks can now be obtained. This is not the same air fork that was recently introduced on 2013 Kawasaki KX450F.
