Definition
Ratio is the relationship between front and rear tooth counts. It changes how quickly the bike accelerates and how relaxed it feels at speed.
Knowledge base
How to choose dirt bike sprocket ratio
Smaller front teeth or a larger rear teeth count lowers gearing; larger front teeth or a smaller rear raises it. The best ratio depends on terrain, traction, and engine feel.
Practical use
Enduro riders often want stronger low-speed drive. Track riders may want taller gearing if the bike is over-revving too quickly.
Material notes
Ratio choice is separate from material choice. Steel or aluminium affects wear and weight, but not the basic gearing math.
Common mistakes
- Changing one sprocket without checking chain length and clearance.
- Choosing a ratio from a different bike or riding surface.
- Ignoring rider weight, terrain, and engine character.
