Here’s a solution from Axis Motorsports for anyone wanting extra performance out of their new KYB PSF (Pneumatic Spring Fork).

There are a lot of smaller parts in the kit, however these are the two main components needed to upgrade the new KYB Air Fork.

The Pro Circuit Mid-Valve Piston replaces the standard two-piece KYB piston. A more modern system with improved oil flow.

This design allows a more progressive valving setting to be utilised, taking harshness out of the fork for a more compliant feel. This ultimately increases rider confidence and reduces rider fatigue.

The Pro Circuit Low Speed Valve replaces the standard KYB part. It holds up the fork by altering oil flow. This reduces diving in the front-end and allows more progression from the top of the fork stroke.

Ideal for riders wanting to ride more aggressively into corners, braking bumps and larger obstacles.

Combine the PC LSV and the billet Pro Circuit Mid-Valve Piston, add the valving setting, the rest of the Pro Circuit Kit (including shock parts) and you get the maximum performance out of your new PSF.

The Pro Circuit Upgrade Kit is $240.00 incl GST (does not including installation). Available for the 2013 Honda CRF450R and Kawasaki KX450F.
