If top-end speed is the priority, this is the most aggressive gearing option in the lineup. The Kraftwerks Sub Trans Final Drive Gear Set (18-31 / 1.722 ratio) significantly reduces gear reduction, allowing your KRX to carry more speed where it matters most.
With a 13.9% reduction compared to stock, this setup is built for riders who want maximum speed potential and are willing to give up low-end torque to get it. It’s best suited for lighter setups, open terrain, and applications where maintaining higher speeds is more important than crawling power.
