Pro Circuit 2006 Linkage System And Linkage Arm

The Pro Circuit Linkage Arms for the Kawasaki KXF and KX models, and Suzuki RM-Z and RM models are designed to stiffen up the initial linkage curve and lower the chassis, making the bike much more stable. This will also help eliminate the initial loose and wallowy feel. Turning and cornering capabilities are greatly improved as well.

And although having your suspension revalved by Pro Circuit would make a considerable improvement, the Linkage Systems and Linkage Arms alone provide a major improvement over the stock setup.

  • Unlike other linkage systems, the Pro Circuit Linkage System for the Honda CRF450R does not require the rider to readjust the static sag, race sag or spring rate after installation.
  • The Pro Circuit Linkage System for the Honda CRF450R flattens out the linkage curve to greatly improve acceleration and deceleration bump absorption, without changing the initial part of the linkage curve.
  • All Pro Circuit Linkage Systems and Arms are CNC-machined from the highest quality T-7075 aluminum, anodized champagne and include all linkage bearings and seals.
