EBMX Competition Jackshaft for Ultra Bee BF25 and preload adjustCompetition uses a jackshaft developed in house by EBMX and used in E Xplorer and global race events. The original Ultra Bee jackshaft was never intended for 50 plus kW, 90 foot jumps and aggressive off road riding. Once you have to ditch the belt due to increased power and required reliability, the original jackshaft starts to fail, from snapping secondary sprocket bolts on landings and completely ovaling the entire body, where the bearings fall out.
