Technical
Crafted with durability and precision in mind, these custom foot pegs are built to withstand the demands of rigorous riding. The high-quality materials used in their construction guarantee longevity, ensuring that they will withstand countless miles of exhilarating adventures.
Images below represent each spring rate starting from stiffest to softest; the Yellow/Red/Blue springs are included within the PS-Series kit, and the Green/Light-Green springs can be purchased as an accessory (A4 “kit, compression springs for lighter riders”).
The top illustration within each spring type represents the preloaded state “top position” and the corresponding reaction force.
The middle illustration represents the “mid-position” or 6.5mm of travel and the corresponding reaction force.
The bottom illustration depicts the “bottom position,” or 13mm of travel, and the corresponding reaction force.
When configuring the PS-Series foot peg to riders’ preference, the following two key points need to be taken into consideration:
A spring that keeps the pegs static under the rider’s weight (including riding gear) at the top position should be chosen. Keeping the platform stationary at the top under the rider’s weight optimizes bike foot control/steering.
Ideally, the Flex Pegs mechanism should initiate movement when additional forces are applied beyond the rider’s weight, e.g., hopping a log or rock, landing after getting airborne, choppy terrain whoops, or rocks.
Reference the “preload” force at the top position, which is required to initiate mechanism movement.
G-forces should also be taken into consideration. As more force gets applied to the Flex Pegs foot peg mechanism, higher spring rates must be installed to compensate for the additional loading. The graph below, “Acceleration vs. Distributed Force,” should be referenced to find the correct spring for riders’ weight and expected g-forces.
See examples below for an average adult’s weight range:
No magic formula will give the perfect setup; each rider should experiment and try all spring rates to get a feel/understanding of each spring stiffness, as everyone’s riding style/preference is different.
Motocross riders can reach acceleration forces beyond 13g’s at the foot pegs when landing after getting airborne; the yellow spring is most applicable for such high g-force riding.
Hard enduro riders or desert racers reach acceleration forces in the 5-10 G range; the red spring is most applicable for this type of riding.
Trail or adventure riders reach acceleration forces up to 5G's; the blue spring is most applicable for this type of riding.
The above graph represents various spring rates (color coded) and the amount of force required to deflect each compression spring throughout the Flex Pegs mechanism vertical travel (13mm). Note that graph represents one spring (50% of load), rider distributes their weight onto two springs (two foot pegs).
The above graph represents how much force is exerted onto a single foot peg while taking riders weight and acceleration into consideration. As riders’ feet expose more acceleration (g-forces) onto each foot peg, the exerted overall force onto each foot pegs increases. Vertical color-coded dotted lines represent low/high compression spring limits (compression spring range). Motocross riders’ feet are exposed to over 13g’s of acceleration when landing. Note that graph represents 50% of riders weight (single foot peg), rider distributes their full weight onto two foot-pegs.
The above graph represents a "zoomed-in" version of how much force is exerted onto a single foot peg while taking riders weight and acceleration into consideration. As riders’ feet expose more acceleration (g-forces) onto each foot peg, the exerted overall force onto each foot pegs increases. Vertical color-coded dotted lines represent low/high compression spring limits (compression spring range). Motocross riders’ feet are exposed to over 13g’s of acceleration when landing. Note that graph represents 50% of riders weight (single foot peg), rider distributes their full weight onto two foot-pegs.
