💡 How does upgrading the front drive sprocket improve acceleration on small displacement mini motorcycles?
- Mount a sixteen tooth gear pinned to a seventeen millimeter shaft when fixing a stuck pit bike primary drive.
- Switching to this exact ratio gets that handy jump in launch speed right off the line without frying light clutch baskets.
- Track nuts strap these direct replicas to ban chain hop on gritty berms and hold max velocity through wet ruts.
