A Note on Recommendations
The jetting and suspension calculators are guides, not gospel. They use simplified physics models and the data you enter. Always cross-reference with your bike's manufacturer specs and consult a qualified mechanic before making changes that could affect engine reliability or rider safety. You ride at your own risk.

Roost MX is in active development. Got feedback? Hit the in-app feedback button — we read every message.
