Why Custom Matters
If someone tells you, “This setup works for everyone,” they’ve never tuned for a real racer. Every rider has a unique style—even world-class champions on identical bikes run different suspension settings.
A Lesson From the Track
Decades ago, while tuning for national championship riders, we swapped setups between two nearly identical bikes. Both riders hated the change. When we switched them back, they battled for the win, swapping the lead twice per lap, finishing inches apart. The lesson? No two riders are the same. Your setup must match YOU.
The American Way: Custom. Competitive. Unstoppable.
Big companies want to tell you what works best. We believe in your right to ride your way.
When your knee skims the pavement, your rear wheel steps out, and you roll on the power, American Suspension is right there with you—keeping that rear tire glued to the pavement and pushing you toward victory.
