APS Suspension System

  • Versatile Suspension Design: APS gives engineers the freedom to develop advanced suspension kinematics beyond the limits of flex-stay and single-pivot systems.
  • Virtual Pivot: The system creates a virtual rear suspension pivot throughout the wheel’s travel, controlled by the upper and lower links and four pivot points.
  • Dynamic Performance: APS allows precise tuning of suspension kinematics for smooth, responsive, and highly controlled performance throughout the entire travel range.

APS Suspension Performance

Uphill Traction:
APS uses progressive anti-squat tuning to allow smooth suspension movement over obstacles while maintaining strong traction and efficient climbing. As the suspension extends, increased anti-squat helps keep the rear wheel connected to the terrain for improved grip.

Downhill Flow:
Reduced pedal kickback deep in the travel keeps the suspension active on technical descents, while minimizing braking interference for greater control and confidence.

Improved Suspension Progressivity:
Updated Fourstroke kinematics and a refined shock tune create a progressive suspension curve for consistent performance across varied terrain.

  • Excellent small-bump sensitivity
  • Strong support in rough terrain
  • Bottomless suspension feel
  • Predictable behavior in the air

The Winning Edge

Extensive testing shows that the Fourstroke with APS Suspension can outperform lighter bikes that rely on weight-saving suspension designs.

The advantage comes from prioritizing traction, suspension efficiency, and pedaling performance over weight alone—delivering faster, more consistent performance when it matters most.
