Description
Stock reeds limit your CR125’s potential across the entire power band, forcing you to sacrifice flow efficiency at both low-end responsiveness and peak acceleration. Boyesen’s dual-stage reed design has been laboratory-proven to outperform standard reeds by permitting greater flow velocity across all operating pressures—meaning you’ll see measurable gains from cold start through top-end pull. This is a straightforward bolt-on upgrade that delivers tangible performance without requiring engine modification.
